#Large hollow blow molding machine: the core technology of modern industrial plastic molding ##1、 Overview of Large Hollow Blow Molding Machines As an important equipment in the plastic processing industry, large hollow blow molding machines play an irreplaceable role in modern industrial production. This type of equipment is mainly used for producing large hollow plastic containers with capacities ranging from tens of liters to thousands of liters, and is widely used in various fields such as chemical, food, medicine, agriculture, etc. Compared with small blow molding machines, large hollow blow molding machines have significant differences in technical parameters, structural design, and application scope, which can meet the production needs of large capacity and high-strength plastic products. The working principle of a large hollow blow molding machine is based on extrusion blow molding technology. By heating and melting thermoplastic raw materials and extruding them to form a preform, the preform is then placed in a mold for blow molding, and finally cooled to obtain the desired hollow product. This process may seem simple, but it actually involves the comprehensive application of multidisciplinary knowledge such as materials science, mechanical engineering, thermodynamics, and control technology. ##2、 Key technical characteristics of large hollow blow molding machines The extrusion system of a large hollow blow molding machine is one of its core components, usually designed with high-efficiency single screw or twin-screw extruders. For large equipment, the extrusion system must have high production capacity, high plasticizing ability, and good mixing performance. The extrusion capacity of modern large-scale blow molding machines can reach hundreds of kilograms per hour, with screw diameters mostly above 90mm, and some ultra large equipment even reaching over 150mm. To meet the processing requirements of different plastic raw materials, extrusion systems are usually equipped with advanced temperature control devices and screen changing systems to ensure stable melt quality. The storage type machine head is another key technology for large hollow blow molding machines. Unlike small blow molding machines, large equipment often adopts vertical or inclined storage tank designs, with a capacity of over 30L. This design solves the problem of weight sagging of medium-sized billets in the production of large products, while ensuring the uniformity of the billet wall thickness. The advanced machine head is also equipped with a wall thickness control system, which controls the thickness of different parts of the billet through programming, optimizes material distribution, improves product quality, and reduces raw material waste. In terms of mold clamping and locking systems, large hollow blow molding machines usually use hydraulic or hydraulic mechanical mold clamping mechanisms, with locking forces ranging from tens to hundreds of tons. Considering the weight and size of large molds, the equipment is often equipped with rapid mold replacement systems and mold preheating devices, significantly improving production efficiency. Some high-end models also use servo drive technology to achieve more precise mold closing control and faster cycle times. ##3、 Application Fields and Development Trends of Large Hollow Blow Molding Machines In the chemical industry, large hollow blow molding machines are mainly used to produce various chemical storage tanks, transport containers, and industrial packaging drums. These products need to have excellent chemical corrosion resistance, impact resistance, and long-term stability. In response to this demand, equipment manufacturers have developed large-scale blow molding machines specifically for processing engineering plastics such as HDPE and PP. Some models can also achieve multi-layer co extrusion to produce composite structure containers with barrier properties. The agricultural sector is another important market for large hollow blow molding machines. Large plastic products such as agricultural water storage tanks, pesticide containers, and livestock feed troughs have special requirements for equipment, such as the ability to produce oversized products and material formulas suitable for outdoor use conditions. Modern large-scale blow molding machines, through optimized design, are capable of producing single piece agricultural containers with a capacity exceeding 1000L, meeting the needs of large-scale development in modern agriculture. Environmental protection and energy conservation are the main trends in the development of large-scale hollow blow molding machines. Equipment manufacturers have significantly reduced energy consumption and raw material waste by improving screw design, optimizing heating systems, and recycling scrap materials. At the same time, advances in the processing technology of bio based plastics and recyclable materials have opened up new application spaces for large-scale blow molding machines.

This equipment adopts extrusion blow molding technology, which can efficiently manufacture large capacity and high-strength hollow plastic products. This article will delve into the working principle, key technologies, application areas, and future development trends of large-scale hollow blow molding machines. ##2. Working principle of large hollow blow molding machine** The large-scale hollow blow molding machine is mainly based on the extrusion blow molding technology, and its process flow can be divided into the following key steps: 1. Plastic melt extrusion: Plastic particles (such as HDPE, PP, etc.) enter the extruder through a hopper and melt and plasticize under heating and screw shearing, forming a uniform melt. 2. * * Material storage and billet forming * *: Molten plastic is extruded through a machine head to form a tubular parison. Large blow molding machines usually use a storage type head, which can store a sufficient amount of melt to ensure that the length and wall thickness of the billet meet the requirements of large capacity products. 3. * * Mold closing and blow molding * *: After the billet enters the mold, the mold quickly closes, and high-pressure air is injected into the interior of the billet to expand and fit the inner wall of the mold. After cooling and shaping, a hollow product is formed. 4. * * Cooling and Demolding * *: The molded product is solidified by the cooling system, and after the mold is opened, it is taken out by a robotic arm or conveyor belt to complete the production cycle. ##III. Key Technologies of Large Hollow Blow Molding Machines** ### **1. Efficient extrusion system** Large hollow blow molding machines are usually equipped with large-diameter single screw or twin-screw extruders to ensure high output and stable melt quality.

Some high-end models use * * barrier type screws * * to reduce melt temperature fluctuations and improve product uniformity. ### **2. Storage type machine head and wall thickness control** Due to the long billet of large products, their own weight can easily cause sagging and deformation, making the storage cylinder type machine head a key configuration. Modern equipment is also equipped with a servo electric or hydraulic wall thickness control system (PWDS), which adjusts the thickness of the billet at different positions through programming, optimizes material distribution, and reduces waste. ### **3. High rigidity mold clamping system** Large blow molding machines need to withstand high-pressure blow molding forces, so hydraulic or hydraulic mechanical hybrid locking mechanisms are used, with locking forces typically ranging from 100 to 1000 tons. Some advanced models are driven by * * servo motors * * to improve mold clamping accuracy and speed, and shorten the molding cycle. ### **4. Automation and Intelligent Control** Modern large-scale blow molding machines widely use PLC (Programmable Logic Controller) and touch screen human-machine interface to achieve precise parameter adjustment. Some high-end models have introduced Internet of Things (IoT) technology, which supports remote monitoring, fault warning, and data analysis, improving production efficiency and equipment stability. ##4. Application Fields of Large Hollow Blow Molding Machines** ### **1. Chemical industry** Used for the production of chemical storage tanks, IBC drums, industrial packaging drums, etc., it is required to have characteristics such as corrosion resistance, impact resistance, and leakage prevention. Multi layer co extrusion blow molding technology can produce barrier containers suitable for storing hazardous chemicals. ### **2. Food and Beverage Industry** Large blow molding machines can manufacture food grade plastic barrels, water storage tanks, alcohol containers, etc., which comply with FDA or EU food contact material standards. ### **3. Agriculture and Environmental Protection Industry** Agricultural water storage tanks, pesticide barrels, livestock feed tanks, etc. all rely on large-scale blow molding machines for production. In addition, the processing technology of recycled plastics (rHDPE) is also promoting the manufacturing of environmentally friendly containers. ### **4. Automotive and logistics industry** Hollow plastic parts such as automotive fuel tanks and large logistics pallets require high mechanical strength and dimensional accuracy, and large blow molding machines can meet their production needs. ##5. Future Development Trends** 1. Energy conservation and environmental protection: Optimize screw design, adopt electromagnetic heating technology to reduce energy consumption, while improving the processing capacity of recycled plastics and reducing carbon emissions. 2. * * Intelligence and Digitalization * *: Combining AI algorithms to optimize process parameters and achieve adaptive control; Utilize big data analysis to predict equipment maintenance needs and reduce downtime. 3. * * Multi layer co extrusion technology * *: Develop 5-7 layer co extrusion blow molding technology to enhance the barrier and UV resistance of containers, meeting high-end packaging needs. 4. * * Oversized and high-precision * *: Develop equipment with greater clamping force and wider molding dimensions to meet the needs of emerging industries such as wind power and shipbuilding. ##VI. Conclusion** As a key equipment for plastic molding, large hollow blow molding machines play an important role in multiple industries. With the advancement of materials science, mechanical manufacturing, and intelligent control technology, its production efficiency, energy-saving and environmental performance, and intelligence level will continue to improve, providing more efficient and sustainable solutions for industrial manufacturing.

It selects high-quality hydraulic components, adopts PLC control, and adopts the most advanced FIFO storage head. On the basis of the advantages of traditional hollow aircraft, coupled with today's most advanced technology, its performance is more excellent and reliable. High efficiency and applicability have reached the level of similar products in Japan and Germany. The tubular plastic parison obtained by extrusion or injection molding of thermoplastic resin is placed in the mold while it is still hot (or heated to a softened state). It is closely attached to the inner wall of the mold, and after cooling and demoulding, it is taken out by a manipulator to obtain various hollow products The producing method of blown film is comparable in theory to blow moulding product, however it doesn’t use mould. From the attitude of plastic process technology classification, the molding method of blown film is typically enclosed in extrusion. The blow molding method began to supply denseness polythene vials from dry throughout war II. within the late Nineteen Fifties, with the birth of high-density polythene and therefore the development of blow molding machines, blow molding technology was wide used. the amount of hollow containers will reach thousands of liters, and a few production has adopted pc management. Plastics appropriate for blow molding embody polyester, vinyl resin, polypropene, polythene,etc., and therefore the obtained hollow containers ar wide used as industrial packaging containers. in step with the tactic of constructing the parison, blow molding may be divided into extrusion blow molding and injection blow molding. The new developed ones embody multi-layer blow molding and stretch blow molding. After more than 20 years of research, blow molding technology has made great progress in both theory and practice. However, combined with relevant information, it is found that the research work of blow molding technology is generally concentrated in a certain period of the molding process. Process-wide analysis Numerical simulations of different process factors are rare. The blow molding process can be roughly refined into three stages: parison molding, parison inflation, and cooling and solidification, and a close correlation is formed between them. The external structural shape and wall thickness distribution of the parison affect the expansion of the parison. The surface profile and wall thickness uniformity have a direct impact: for the parison inflation stage, the compressed air and the product thickness and temperature distribution obtained after inflation will affect the cooling and solidification process of the product, thereby affecting the product performance.Based on the above discussion, it is found that it is of great practical significance to strengthen the systematic numerical simulation of the whole process of blow molding, and to ensure the continuity of the simulation process, and then to more accurately describe the entire process of product molding, and the level of blow molding technology is also will increase accordingly. In the era of rapid social and economic development, the demand for hollow plastic products in various industries is increasing, and higher requirements are also placed on product quality, and the geometry of additional products is also becoming more and more complicated. In the process of plastic products, it has been stagnant for a long time in the production state of repeated mold trials in the past, so it is difficult to ensure that the production enterprises have a place to stand in the fierce market environment, and even have the risk of being eliminated. Based on the status quo, it is found that the related technologies of hollow blow molding in my country started relatively slowly, but developed rapidly in the later stage. Universities and major enterprises are actively participating in the research process of this technology. Diversity has a positive effect. Weifang Huayu Plastic Machinery Co., Ltd. was founded in 2002, a manufacturer specialized in super large automatic blow moulding machines.

What is blow molding technology? Also known as blow molding, raw materials are extruded or injected to form plastic preforms. Place it in the open mold while it is still hot, and after closing the mold, introduce compressed air into the billet to inflate it and tightly adhere to the inner wall of the mold. After cooling, demold it to form various hollow blow molded products. What is injection molding process? A method of industrial product production modeling. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding, compression molding, and die-casting methods. Injection molding machine (abbreviated as injection machine or injection molding machine) is the main molding equipment that uses plastic molding molds to produce various shapes of plastic products from thermoplastic or thermosetting materials. Injection molding is achieved through injection molding machines and molds. The difference between blow molded and injection molded products In blow molding, the billet is formed by the machine head under low pressure and inflated at low pressure, mostly 0.2-1.0 MPa. Therefore, the residual stress of the product is small, and it has high resistance to various strains such as tension, impact, bending, and environmental factors, and has good usability. In injection molding, the melt needs to pass through the mold runner and gate under high pressure of 15-140 MPa, which can lead to uneven stress distribution. Blow molded plastics, such as PE, have a much higher relative molecular weight than injection grade plastics. The wall thickness of the product is uniform and consistent, and there is no need for post-processing. The product has no seam lines and minimal waste edges. Blow molded products are hollow, so their weight is lighter, while injection molded products have more structural components, so their weight is relatively heavier than blow molded products. Advantages of blow molding process Hollow blow molding machines have a small footprint, simple structure, and easy operation, requiring only 3-4 people. Blow molded products are generally made of high molecular weight high-density polyethylene resin, which is extruded and blow molded in one go. The molding process is fast and thorough; The product is fully formed, with stable internal quality and performance. Generally, a hollow blow molding machine can produce an average of 18-20 plastic water buckets per hour. For example, a 2000L water bucket weighing 40Kg can produce 8-9 pieces per hour. 1-2 workers can proficiently operate the fully automatic hollow blow molding machine, which is easy, labor-saving, and fast to operate. The product is lightweight, easy to handle, long-lasting, durable, wear-resistant, and drop resistant. Generally, it can have a multi-layer structure, and the defects caused by the fusion of plastic melt in each layer are staggered, greatly improving the impact resistance of the plastic bucket. The multi-layer structure of the hollow blow molded plastic bucket has multiple concepts: the outer layer is dark (blue), which can resist ultraviolet rays and light aging, and the inner layer is natural resin to ensure the purity of the contents and better use. The middle inner layer is made of recycled materials, which comply with the recycling co extrusion (RECOM) rules and are environmentally friendly. The outer layer is made of new raw materials while ensuring overall quality. Hollow blow molded plastic drums are made of high molecular weight high-density low-pressure polyethylene raw materials, which have the characteristics of high rigidity, creep resistance, wear resistance, and environmental stress cracking resistance. It can be widely used in packaging industries such as petroleum, chemical, pharmaceutical, and food.   Advantages of Huayu blow molding machine The company was founded in 2002 and has over 18 years of technical experience.

Blow molding machine, also known as hollow blow molding, is a rapidly developing plastic processing method. Blow molding machine is a machine that sprays liquid plastic and uses the wind force blown by the machine to attach the plastic body to a mold cavity of a certain shape, thereby producing products. Blow molding machines can be divided into three categories: extrusion blow molding machines, injection blow molding machines, and special structure blow molding machines. Hollow forming machine, mainly composed of extruder, head, hydraulic system, mold closing system, electrical control system, inflation system, automatic clamping and other parts, is used for blowing hollow products of PE and other various materials. Such as square barrels, round barrels, beer preservation containers, toolboxes, lampshades, etc. This machine has high performance, low energy consumption, and easy operation. At present, the high-end hollow machine on the market is a leading updated product developed and researched based on China's national conditions. It uses high-quality hydraulic components, adopts PLC control, and the most advanced first in first out material storage head. On the basis of the advantages of traditional hollow machines and the most advanced technology today, its performance is more outstanding and reliable. High efficiency and applicability have reached the level of similar products in Japan and Germany. The tubular plastic preform obtained by extrusion or injection molding of thermoplastic resin is placed in a split mold while it is hot (or heated to a softened state). After closing the mold, compressed air is immediately introduced into the preform to inflate it and tightly adhere to the inner wall of the mold. After cooling and demolding, it is removed by a robotic arm to obtain various hollow products. The manufacturing process of blown film is very similar in principle to blow molding of hollow products, but it does not use molds. From the perspective of plastic processing technology classification, the molding process of blown film is usually included in extrusion. Blow molding technology began to produce low-density polyethylene small bottles using dry methods during World War II. In the late 1950s, with the birth of high-density polyethylene and the development of blow molding machines, blow molding technology was widely applied. The volume of hollow containers can reach thousands of liters, and some production has adopted computer control. Plastics suitable for blow molding include polyethylene, polyvinyl chloride, polypropylene, polyester, etc. The resulting hollow containers are widely used as industrial packaging containers. According to the production method of preforms, blow molding can be divided into extrusion blow molding and injection blow molding, with newly developed methods including multi-layer blow molding and stretch blow molding. After more than 20 years of research, blow molding technology has made great progress both in theory and practice. However, based on relevant data, it has been found that the research on blow molding technology is generally focused on a certain period of the molding process, and numerical simulation of different process factors for the overall analysis of the entire process is relatively rare. The blow molding process can be roughly refined into three stages: billet forming, billet inflation, and cooling and solidification, which form a close correlation. The external structural shape and wall thickness distribution of the billet directly affect the surface contour and wall thickness uniformity of the billet inflation. For the billet inflation stage, the compressed air and the thickness and temperature distribution of the product obtained after inflation will affect the cooling and solidification process of the product, thereby affecting the performance of the product. Based on the above discussion, it is found that strengthening the systematic numerical simulation of the entire blow molding process has great practical significance and ensures the continuity of the simulation process, thereby more accurately explaining the entire process of product molding. The level of blow molding technology will also be correspondingly improved. In the context of rapid socio-economic development, there is a growing demand for hollow plastic products in various industries, and higher requirements are being put forward for product quality. In addition, the geometric shapes of products are becoming increasingly complex. If enterprises are stuck in the production state of repeated mold testing in the manufacturing process of hollow plastic products for a long time, it is difficult to ensure that they have a foothold in the fierce market environment, and there is even a risk of being eliminated. Based on the current situation, it is found that China's hollow blow molding technology started relatively slowly, but developed rapidly in the later stage. Universities and major enterprises are actively involved in the research process of this technology, which promotes the output of new production methods and the diversification of equipment.

The difference between blow molding and rotational molding First of all, you need to have a concept of blow molding and rotomolding. In order to have a deeper understanding of the difference and characteristics of rotomolding and rotomolding. What is blow molding? Blow molding can also be called hollow blow molding. The raw material is a plastic parison formed by extrusion or injection. During the operation, the parison needs to be put into the split mold while it is still hot, and after the mold is closed, it is compressed in the parison. The air causes the plastic parison to expand and stick to the inner wall of the mold. After a period of cooling, the mold is released immediately to form various hollow blow molding products. What is rotomolding? Rotational molding, also known as rotational molding, rotational molding, rotary molding, etc., is a method of plastic hollow molding. The raw material is added to the mold, the mold is continuously rotated and heated along the two vertical axes, and the raw material in the mold is gradually and uniformly coated and melted and adhered to the entire surface of the mold cavity under the action of gravity and thermal energy, and then initially formed as The desired shape is cooled and shaped to form the corresponding rotomoulded product. What are the characteristics of blow molding and rotational molding? Next, let's talk about the characteristics of blow molding and rotational molding. Blow molding: (1) In blow molding, the parison is formed by the machine head under low pressure and blown under low pressure (mostly 0.2-1.0mpa), so the residual stress of the product is small, and it is resistant to stretching, The performance of various strains such as impact, bending and environment is high, and it has better performance. In injection molding, the melt must pass through the mold runner and gate under high pressure (15~140mpa), which will lead to uneven stress distribution. The relative molecular mass of blow molding plastic is much higher than that of injection plastic. (2) The relative molecular mass of blow molding grade plastics is much higher than that of injection grade plastics. (3) The blow molding machine occupies a small area, the structure is relatively simple, and it is easy to operate, and 3-5 people can operate the production of one machine. (The rotomolding machine occupies a large area and has a simple structure, but It is difficult to operate and requires a lot of labor) Rotational molding: (1) Quality advantage: During the entire production process of rotomolded products, the product quality and structure are more stable due to the generation of no internal stress. (2) The advantages of flexibility and change. The machine mold of the rotational molding process is easy to manufacture and cheap, so it is especially suitable for the production of multiple varieties and small batches in the development of new products.

Blowing molding is a common plastic molding process and is widely used to manufacture hollow plastic products. This process involves heating the plastic material to a molten state and then blowing it into the desired shape. Blowing molding is mainly divided into the following several types: Extruded blow molding: 1. This is the most common method of blow molding, used in the production of bottles, containers, and other hollow products. The process is as follows: Heat and extrude the plastic particles into a hollow tubular molten plastic (called a type or pre-blank).Clip the blank in the mold and blow into the blank through the nozzle to expand and fit to the inner wall of the mold to form the desired shape.After cooling, open the mold and remove the finished product. Injection blow molding (Injection Blow Molding): -This method is suitable for small and high-precision hollow products, such as medicine bottles and cosmetic containers. The process is as follows: -inject the plastic into a mold to form a prefabricated billet.-Transfer the prefabricated billet to the blow mold and expand it by blowing. After cooling, remove the finished product. Tensile blowing (Stretch Blow Molding): Usually used for the production of PET beverage bottles. The process is as follows: -inject the plastic material into a prefabricated billet. Heat the billet and put it into the blow mold.-Pull the simultaneously axially and radially by mechanical device and air pressure to form the desired bottle shape.-After cooling, remove the finished product. The advantages of the blowing process include: Can produce hollow products with complex shape and stable size.-High productive efficiency and suitable for mass manufacturing.-High material utilization rate, less waste material. Due to its wide application and efficient production capacity, the blowing process has been widely used in packaging, automobiles, toys and household goods.

What is the blow molding process?   Also known as blow molding, the raw material is extruded or injected to form a plastic parison. Put it into the split mold while it is still hot, and after the mold is closed, compressed air is introduced into the parison, so that the plastic parison is inflated and adhered to the inner wall of the mold. After cooling, it is demolded to form various hollow blow molding products.   What is the injection molding process?   A method of producing shapes for industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding and die casting. Injection molding machine (referred to as injection machine or injection molding machine) is the main molding equipment for making thermoplastics or thermosets into various shapes of plastic products using plastic molding molds. Injection molding is achieved by injection molding machines and molds.   The difference between blow molding and injection molding products   In blow molding, the parison is formed by the machine head at a lower pressure and blown at a low pressure, mostly 0.2-1.0mpa, so the residual stress of the product is small, and it is resistant to stretching, impact, bending and the environment. This strain has higher performance and better performance. In injection molding, the melt must pass through the mold runner and gate under high pressure of 15-140mpa, which will cause uneven stress distribution. The relative molecular mass of blow molding grade plastics, such as PE, is much higher than that of injection grade plastics. The wall thickness of the product is uniform, no post-modification processing is required, the product has no stitches, and there are few waste edges. Blow-molded products are hollow, so the weight is lighter, while injection-molded products will be heavier than blow-molded parts because of their many structural parts.   Advantages of blow molding The hollow blow molding machine occupies a small area, has a simple structure, and is easy to operate. It only needs 3-4 people. Blow-molded products are generally made of high-molecular-weight high-density polyethylene resin, which is extruded and blown once. The molding process is fast and sufficient; the product is fully formed, and the internal quality and performance are stable. Generally, the hollow blow molding machine can produce 18-20 plastic buckets per hour on average. For example, a 2000L bucket with a weight of 40Kg can produce 8-9 pieces per hour. 1-2 workers can be skilled in operation, and the automatic hollow blow molding machine is easy to operate, labor-saving and fast. The product is light in texture, easy to handle, long-lasting, durable and wear-resistant. Generally, it can have a multi-layer structure, and each layer is formed by melting the plastic melt at one time, and the defects caused by it are staggered, which greatly improves the impact resistance of the plastic barrel. The multi-layer structure of the hollow blow-molded plastic barrel has multiple concepts: the outer layer is dark (blue), which can resist ultraviolet rays and light aging, and the inner layer is the natural color of the resin, which ensures the purity of the contents and makes it easier to use. The middle inner layer adopts recycled material, which conforms to the rules of recycling co-extrusion (RECO), which is beneficial to environmental protection, and the outer layer adopts new raw materials while ensuring the overall quality. The hollow blow molding plastic barrel is made of high molecular weight high density low pressure polyethylene raw material, which has the characteristics of high rigidity, creep resistance, wear resistance and environmental stress crack resistance. Can be widely used in petroleum, chemical, pharmaceutical, food and other industries packaging.     Advantages of Huayu blow molding machine 1.

The energy saving of the extrusion blow molding machine can be divided into two parts: one is the power part and the other is the heating part. Power part energy saving: most of the use of inverter, energy saving is to save the residual energy of the motor, such as the actual power of the motor is 50Hz, and you actually only need 30Hz in the production is enough to produce, the excess energy consumption is wasted, the inverter is to change the power output of the motor to achieve energy-saving effect. Heating part energy saving: heating part energy saving is mostly the use of electromagnetic heater energy saving, energy saving rate is about 30%-70% of the old resistor ring. 1. Compared with resistance heating, the electromagnetic heater has more than one layer of insulation layer, and the heat energy utilization rate is increased. 2. Compared with resistance heating, the electromagnetic heater directly acts on the material pipe heating, reducing the heat transfer loss. 3. Compared with resistance heating, the heating speed of the electromagnetic heater is more than a quarter faster, reducing the heating time. (4) Compared with resistance heating, the heating speed of the electromagnetic heater is fast, the production efficiency is improved, so that the motor is in a saturated state, so that it reduces the power loss caused by high power and low demand. The above four points are why the electromagnetic heater can save energy up to 30%-70% on the blow molding machine.

Extrusion blow molding machine, also known as hollow blow molding, is a rapidly developing plastic processing method. The tubular plastic billet obtained by extrusion or injection molding of thermoplastic resin is hot and placed in a split mold. Compressed air is passed into the billet immediately after the mold is closed, so that the plastic billet is blown and close to the inner wall of the mold. After cooling and demoulding, various hollow products are obtained. The manufacturing process of blow molded film is very similar in principle to that of blow molded hollow products, but it does not use molds, and the molding process of blow molded film is usually included in the extrusion from the perspective of plastic processing technology classification. The blow molding process began to be used to produce low density polyethylene vials during World War II. In the late 1950s, with the birth of high-density polyethylene and the development of blow molding machines, blow molding technology has been widely used. The volume of hollow containers can reach thousands of liters, and some production has been controlled by computers. The plastics suitable for blow molding are polyethylene, polyvinyl chloride, polypropylene, polyester, etc., and the resulting empty containers are widely used as industrial packaging containers. According to the production method of billet, blow molding can be divided into extrusion blow molding and injection blow molding, and the newly developed multi-layer blow molding and tensile blow molding.

Blow moulding machine, also called hollow blow moulding, is a rapidly developing method of plastic processing. A blow moulding machine is a machine that uses the wind blowing from the machine to blow the plastic body to a certain shape of the cavity after spraying the liquid plastic to make the product. Blow moulding machines can be classified into three categories: extrusion blow moulding machines, injection blow moulding machines and special structure blow moulding machines. Blow moulding machine is mainly composed of hydraulic system, extruder,mold clamping system, die head electrical control system, inflation system, automatic clamping and other parts.It is used for blowing PE and other hollow products of various materials. Such as: square barrels, round barrels, beer preservation containers, tool boxes, lampshades, etc. The machine has high performance, low energy consumption and easy operation. At present, the high-end hollow machine on the market is a newer product developed and developed in combination with my country's national conditions. It selects high-quality hydraulic components, adopts PLC control, and adopts the most advanced FIFO storage head. On the basis of the advantages of traditional hollow aircraft, coupled with today's most advanced technology, its performance is more excellent and reliable. High efficiency and applicability have reached the level of similar products in Japan and Germany. The tubular plastic parison obtained by extrusion or injection molding of thermoplastic resin is placed in the mold while it is still hot (or heated to a softened state). It is closely attached to the inner wall of the mold, and after cooling and demoulding, it is taken out by a manipulator to obtain various hollow products The producing method of blown film is comparable in theory to blow moulding product, however it doesn’t use mould. From the attitude of plastic process technology classification, the molding method of blown film is typically enclosed in extrusion. The blow molding method began to supply denseness polythene vials from dry throughout war II. within the late Nineteen Fifties, with the birth of high-density polythene and therefore the development of blow molding machines, blow molding technology was wide used. the amount of hollow containers will reach thousands of liters, and a few production has adopted pc management. Plastics appropriate for blow molding embody polyester, vinyl resin, polypropene, polythene,etc., and therefore the obtained hollow containers ar wide used as industrial packaging containers. in step with the tactic of constructing the parison, blow molding may be divided into extrusion blow molding and injection blow molding. The new developed ones embody multi-layer blow molding and stretch blow molding. After more than 20 years of research, blow molding technology has made great progress in both theory and practice. However, combined with relevant information, it is found that the research work of blow molding technology is generally concentrated in a certain period of the molding process. Process-wide analysis Numerical simulations of different process factors are rare. The blow molding process can be roughly refined into three stages: parison molding, parison inflation, and cooling and solidification, and a close correlation is formed between them. The external structural shape and wall thickness distribution of the parison affect the expansion of the parison. The surface profile and wall thickness uniformity have a direct impact: for the parison inflation stage, the compressed air and the product thickness and temperature distribution obtained after inflation will affect the cooling and solidification process of the product, thereby affecting the product performance.Based on the above discussion, it is found that it is of great practical significance to strengthen the systematic numerical simulation of the whole process of blow molding, and to ensure the continuity of the simulation process, and then to more accurately describe the entire process of product molding, and the level of blow molding technology is also will increase accordingly. In the era of rapid social and economic development, the demand for hollow plastic products in various industries is increasing, and higher requirements are also placed on product quality, and the geometry of additional products is also becoming more and more complicated. In the process of plastic products, it has been stagnant for a long time in the production state of repeated mold trials in the past, so it is difficult to ensure that the production enterprises have a place to stand in the fierce market environment, and even have the risk of being eliminated. Based on the status quo, it is found that the related technologies of hollow blow molding in my country started relatively slowly, but developed rapidly in the later stage. Universities and major enterprises are actively participating in the research process of this technology. Diversity has a positive effect.

Blow molding and rotational molding are two common blow molding processes. What is the difference between blow molding and rotomolding? Which molding process is better? First of all, let's understand the concept of blow molding process and rotational molding process. Learn about the difference between blow molding and rotational molding.   What is the blow molding process?   Also known as blow molding, the raw material is extruded or injected to form a plastic parison. Put it into the split mold while it is still hot, and after the mold is closed, compressed air is introduced into the parison, so that the plastic parison is inflated and adhered to the inner wall of the mold. After cooling, it is demolded to form various hollow blow molding products.   What is rotomolding process?   Also known as rotational molding, rotational molding, and rotary molding, it is a method of plastic hollow molding. The raw material is added to the mold, the mold is continuously rotated and heated along the two vertical axes, and the raw material in the mold is gradually and uniformly coated and melted and adhered to the entire surface of the mold cavity under the action of gravity and thermal energy, and is initially formed as required. The shape of the product is cooled and shaped into a corresponding rotomolded product.   Next, the difference between blow molding and rotational molding will be compared from different aspects.   Machine construction for blow and rotomolding   The hollow blow molding machine occupies a small area, has a simple structure, and is easy to operate. It only needs 3-4 people.     The rotomolding machine occupies a large area and has a simple structure, but the operation is more complicated and often requires a lot of labor.   Production efficiency in blow and rotomolding   Blow-molded products are generally made of high-molecular-weight high-density polyethylene resin, which is extruded and blown once. The molding process is fast and sufficient; the product is fully formed, and the internal quality and performance are stable. Generally, the hollow blow molding machine can produce 18-20 plastic buckets per hour on average. For example, a 2000L bucket with a weight of 40Kg can produce 8-9 pieces per hour. 1-2 workers can be skilled in operation, and the automatic hollow blow molding machine is easy to operate, labor-saving and fast.   The processing speed of rotomolding is slow. For the same 2000L bucket, the output of rotomolding is only 1-2 pieces per hour. In addition, rotomolding has high requirements on raw materials and less plastic material is available. In addition, large-scale rotomolding, 3-4 workers, is labor-intensive, long processing cycle, and high cost. Therefore, it is not suitable for large-scale assembly line production. Production of multi-layer products for blow and rotomolding   The multi-layer blow-molded product uses a strong UV-stabilized outer layer, a black middle layer, and a virgin polymer inner layer that is in direct contact with drinking water. Multiple layers in the blow molding process can be formed at the same time, so the bonding between each layer is very tight 1. Introduction to the advantages and performance of hollow blow molding products 1. The product is light in texture, easy to handle, long-term use, durable, wear-resistant and anti-fall. Generally, it can have a multi-layer structure, and each layer is formed by melting the plastic melt at one time, and the defects caused by it are staggered, which greatly improves the impact resistance of the plastic barrel. The multi-layer structure of the hollow blow-molded plastic barrel has multiple concepts: the outer layer is dark (blue), which can resist ultraviolet rays and light aging, and the inner layer is the natural color of the resin, which ensures the purity of the contents and makes it easier to use. The middle inner layer adopts recycled material, which conforms to the rules of recycling co-extrusion (RECO), which is beneficial to environmental protection, and the outer layer adopts new raw materials while ensuring the overall quality. 2. The hollow blow molding plastic barrel is made of high molecular weight high density low pressure polyethylene raw material, which has the characteristics of high rigidity, creep resistance, wear resistance and environmental stress crack resistance. Can be widely used in petroleum, chemical, pharmaceutical, food and other industries packaging.   In conclusion, the hollow blow molding machine adopts multi-layer die technology. Realize the production of multi-layer products. Improve material recycling rate, reduce material cost, and increase production efficiency accordingly.   In the rotomolding process, each layer needs to be added separately in each molding process, which will reduce the adhesion between each layer, cannot guarantee the quality of the product, and also cause a waste of manpower and time. Which one is better quality and stronger about blow molded products and rotomolded products? The answer, of course, is blow molding products. The products produced by the blow molding process have good color, light weight, thick and uniform wall thickness, and good quality. In rotomolding, because the plastic is melted by fire and then cooled and formed, the factors affecting the quality of the product are difficult to control, and there are often quality problems such as uneven wall thickness of the product, large dimensional errors, and impurities on the surface of the product. In simple terms, blow molded products are more rigid than rotomolded products, and are more resistant to creep, wear and environmental stress cracking, and are more resistant to collisions and lower transportation costs.   In addition, in terms of energy consumption, blow molding is more energy-efficient than rotomolding.   At present, in the design and production of hollow blow molding machines, induction heaters are used for the die and extruder, which can save 40% to 50% of energy. The use of servo motors for the clamping device of the machine can save 40% of energy. The reduction in energy consumption also saves certain production costs.   Compared with rotomolding and blow molding, there is a lot more manual work. For example, in the production process of rotational molding, specialized workers are needed to open and close the mold. Opening and closing the mold is a heavy manual labor. This requires a lot of labor and labor costs. The fuel used in rotomolding keeps the temperature at a high level that is dangerous for workers or the process of adding raw materials. Fuel combustion also produces gases that pollute the environment. After the production of one product, in order to produce the next product as soon as possible, when the mold is still hot, it is necessary to pour cold water on it to cool it down, and the cost of fuel is very high, which results in a waste of resources.     This is a summary of the above. According to what we have said above, it should be seen that the cost of the blow molding process is lower, the blow molding requires less labor, high production efficiency, low material requirements, low material cost, Less energy consumption, etc.   The above is the process comparison between blow molding and rotational molding. In the long run, the blow molding process brings us a wider range of benefits. The blow molding process has so many advantages, and the advantages of the hollow blow molding machine using the blow molding process are beyond doubt.  

What is the blow molding process?   Also known as blow molding, the raw material is extruded or injected to form a plastic parison. Put it into the split mold while it is still hot, and after the mold is closed, compressed air is introduced into the parison, so that the plastic parison is inflated and adhered to the inner wall of the mold. After cooling, it is demolded to form various hollow blow molding products.   What is the injection molding process?   A method of producing shapes for industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding and die casting. Injection molding machine (referred to as injection machine or injection molding machine) is the main molding equipment for making thermoplastics or thermosets into various shapes of plastic products using plastic molding molds. Injection molding is achieved by injection molding machines and molds.   The difference between blow molding and injection molding products   In blow molding, the parison is formed by the machine head at a lower pressure and blown at a low pressure, mostly 0.2-1.0mpa, so the residual stress of the product is small, and it is resistant to stretching, impact, bending and the environment. This strain has higher performance and better performance. In injection molding, the melt must pass through the mold runner and gate under high pressure of 15-140mpa, which will cause uneven stress distribution. The relative molecular mass of blow molding grade plastics, such as PE, is much higher than that of injection grade plastics. The wall thickness of the product is uniform, no post-modification processing is required, the product has no stitches, and there are few waste edges. Blow-molded products are hollow, so the weight is lighter, while injection-molded products will be heavier than blow-molded parts because of their many structural parts.   Advantages of blow molding The hollow blow molding machine occupies a small area, has a simple structure, and is easy to operate. It only needs 3-4 people. Blow-molded products are generally made of high-molecular-weight high-density polyethylene resin, which is extruded and blown once. The molding process is fast and sufficient; the product is fully formed, and the internal quality and performance are stable. Generally, the hollow blow molding machine can produce 18-20 plastic buckets per hour on average. For example, a 2000L bucket with a weight of 40Kg can produce 8-9 pieces per hour. 1-2 workers can be skilled in operation, and the automatic hollow blow molding machine is easy to operate, labor-saving and fast. The product is light in texture, easy to handle, long-lasting, durable and wear-resistant. Generally, it can have a multi-layer structure, and each layer is formed by melting the plastic melt at one time, and the defects caused by it are staggered, which greatly improves the impact resistance of the plastic barrel. The multi-layer structure of the hollow blow-molded plastic barrel has multiple concepts: the outer layer is dark (blue), which can resist ultraviolet rays and light aging, and the inner layer is the natural color of the resin, which ensures the purity of the contents and makes it easier to use. The middle inner layer adopts recycled material, which conforms to the rules of recycling co-extrusion (RECO), which is beneficial to environmental protection, and the outer layer adopts new raw materials while ensuring the overall quality. The hollow blow molding plastic barrel is made of high molecular weight high density low pressure polyethylene raw material, which has the characteristics of high rigidity, creep resistance, wear resistance and environmental stress crack resistance. Can be widely used in petroleum, chemical, pharmaceutical, food and other industries packaging.     Advantages of Huayu blow molding machine 1.

The working principle of blow moulding machine     Blow moulding machine, also called hollow blow moulding, is a rapidly developing method of plastic processing. A blow moulding machine is a machine that uses the wind blowing from the machine to blow the plastic body to a certain shape of the cavity after spraying the liquid plastic to make the product.     Blow moulding machines can be classified into three categories: extrusion blow moulding machines, injection blow moulding machines and special structure blow moulding machines.     Blow moulding machine is mainly composed of hydraulic system, extruder,mold clamping system, die head electrical control system, inflation system, automatic clamping and other parts.It is used for blowing PE and other hollow products of various materials. Such as: square barrels, round barrels, beer preservation containers, tool boxes, lampshades, etc. The machine has high performance, low energy consumption and easy operation.     At present, the high-end hollow machine on the market is a newer product developed and developed in combination with my country's national conditions. It selects high-quality hydraulic components, adopts PLC control, and adopts the most advanced FIFO storage head.            On the basis of the advantages of traditional hollow aircraft, coupled with today's most advanced technology, its performance is more excellent and reliable. High efficiency and applicability have reached the level of similar products in Japan and Germany. The tubular plastic parison obtained by extrusion or injection molding of thermoplastic resin is placed in the mold while it is still hot (or heated to a softened state). It is closely attached to the inner wall of the mold, and after cooling and demoulding, it is taken out by a manipulator to obtain various hollow products     The producing method of blown film is comparable in theory to blow moulding product, however it doesn’t use mould. From the attitude of plastic process technology classification, the molding method of blown film is typically enclosed in extrusion. The blow molding method began to supply denseness polythene vials from dry throughout war II. within the late Nineteen Fifties, with the birth of high-density polythene and therefore the development of blow molding machines, blow molding technology was wide used. the amount of hollow containers will reach thousands of liters, and a few production has adopted pc management. Plastics appropriate for blow molding embody polyester, vinyl resin, polypropene, polythene,etc., and therefore the obtained hollow containers ar wide used as industrial packaging containers. in step with the tactic of constructing the parison, blow molding may be divided into extrusion blow molding and injection blow molding. The new developed ones embody multi-layer blow molding and stretch blow molding.     After more than 20 years of research, blow molding technology has made great progress in both theory and practice. However, combined with relevant information, it is found that the research work of blow molding technology is generally concentrated in a certain period of the molding process. Process-wide analysis Numerical simulations of different process factors are rare. The blow molding process can be roughly refined into three stages: parison molding, parison inflation, and cooling and solidification, and a close correlation is formed between them. The external structural shape and wall thickness distribution of the parison affect the expansion of the parison. The surface profile and wall thickness uniformity have a direct impact: for the parison inflation stage, the compressed air and the product thickness and temperature distribution obtained after inflation will affect the cooling and solidification process of the product, thereby affecting the product performance.Based on the above discussion, it is found that it is of great practical significance to strengthen the systematic numerical simulation of the whole process of blow molding, and to ensure the continuity of the simulation process, and then to more accurately describe the entire process of product molding, and the level of blow molding technology is also will increase accordingly.     In the era of rapid social and economic development, the demand for hollow plastic products in various industries is increasing, and higher requirements are also placed on product quality, and the geometry of additional products is also becoming more and more complicated. In the process of plastic products, it has been stagnant for a long time in the production state of repeated mold trials in the past, so it is difficult to ensure that the production enterprises have a place to stand in the fierce market environment, and even have the risk of being eliminated. Based on the status quo, it is found that the related technologies of hollow blow molding in my country started relatively slowly, but developed rapidly in the later stage. Universities and major enterprises are actively participating in the research process of this technology. Diversity has a positive effect.     Weifang Huayu Plastic Machinery Co., Ltd. was founded in 2002, a manufacturer specialized in super large automatic blow moulding machines.
