1100L Automatic 2-Layer Co-extrusion IBC Blow Moulding Machine for HDPE Chemical Tanks

This Huayu 1100L 2-layer co-extrusion blow moulding machine is specially developed for manufacturing 1000L–1100L IBC intermediate bulk containers, widely used for HDPE chemical liquid storage tanks, water storage containers and large plastic hollow packaging products. It adopts mature two-layer co-extrusion forming technology, which can separate the inner and outer material layers to meet different functional requirements of customers. Different raw materials can be used for the inner and outer layers respectively, such as anti-ultraviolet material for the outer layer and food-grade or anti-corrosion material for the inner layer, greatly expanding the application range of finished IBC tanks.

The whole machine is built with heavy-duty frame structure, thickened welding base and high-rigidity guide rail assembly, which effectively reduces vibration during long-time continuous production. The extruder system is equipped with high-efficiency plasticizing screw and barrel, with uniform plasticization and stable melt output. The two independent extrusion channels realize precise material feeding for each layer, and the wall thickness control system monitors and adjusts the parison in real time along the axial and radial directions. It ensures consistent wall thickness distribution of the IBC tank, avoids partial thin or uneven positions, reduces material waste and improves the strength and impact resistance of final containers.

This model is configured with servo hydraulic driving system. Compared with traditional constant pump hydraulic solutions, it can adjust pressure and flow according to actual working conditions of mould clamping, lifting and parison extrusion. It significantly cuts down idle power consumption, lowers heat generation of hydraulic oil and extends the service life of hydraulic components. The clamping unit uses large force toggle structure, which provides strong and balanced clamping force. It can lock the mould tightly under high melt pressure, effectively prevent flash and burr on the tank surface, and guarantee stable forming quality for each finished product.

The human-machine operation interface is clear and easy to operate. All production parameters including extrusion speed, parison length, wall thickness curve, mould closing speed, holding time and cooling time can be set, stored and called directly on the touch screen. Multiple sets of product recipes can be saved in the system. When switching between different moulds or different material formulas, operators can quickly recall the preset parameters instead of repeated debugging, which greatly saves mould change time and improves production efficiency. The system has complete fault alarm and self-check functions. Once abnormal pressure, temperature, position or action signal appears, the device will trigger alarm and display fault prompts on the screen to help maintenance staff locate problems rapidly.

For the mould part, the machine supports custom mould installation according to customer’s IBC drawing requirements. Mould cooling channels are designed with dense and uniform runner layout to realize fast and balanced cooling of the tank body. Fast cooling shortens each forming cycle, raises daily output and reduces internal stress of plastic products. Finished IBC tanks made by this machine feature smooth surface, stable size, good drop resistance and stacking performance, meeting standard test requirements for bulk liquid packaging.

Safety design runs through the whole equipment. Safety grating, safety door interlock, emergency stop button and pressure protection devices are installed on key positions. When operators enter the danger zone or open the safety door during operation, the machine will stop dangerous actions immediately to protect on-site workers. All electrical and hydraulic components adopt reliable well-known brands, with stable supply and convenient after-sales support. The machine can run continuously for 24 hours under normal maintenance, suitable for medium and large plastic packaging factories with stable mass production demand.

This 1100L two-layer IBC blow moulding machine is widely favored by customers from many countries. It can produce containers for chemical solvent, industrial raw material, liquid fertilizer, drinking water and other scenarios. Compared with single-layer blow moulding equipment, the two-layer structure brings more flexible material matching solutions. Customers can add anti-static, anti-UV, anti-oxidation or barrier materials as needed without increasing too much production cost.

Our technical team provides full set of supporting services, including equipment installation guidance, on-site commissioning, operator training, mould matching suggestion, process parameter optimization and regular after-sales follow-up. We supply detailed operation manual, electric schematic diagram and hydraulic drawing together with the machine. If customers encounter operation or process problems during production, our engineers can offer remote guidance or arrange on-site service as agreed.

Huayu focuses on large hollow blow moulding equipment research and manufacturing for years. We keep optimizing machine structure, energy consumption control and forming stability according to actual feedback from production workshops. This 1100L 2-layer IBC blow moulding machine balances high production capacity, stable quality and reasonable operation cost, becoming a preferred solution for customers who plan to invest in IBC tank production lines. It supports matching with auxiliary machines such as material dryer, mixer, crusher and chiller to form a complete automatic production line.
