Huayu 4000L Single Layer Blow Molding Machine for Large Plastic Water Tank

The Huayu 4000L Single Layer Blow Molding Machine is a heavy-duty accumulator head extrusion blow molding equipment professionally developed for manufacturing large-capacity 4000-liter HDPE water storage tanks. Designed for large hollow plastic product production, this single-layer blow molding unit features robust mechanical structure, precise molding control, outstanding operational stability and excellent energy-saving performance, fully catering to mass production needs for industrial water tanks, agricultural storage tanks, domestic water containers and general chemical storage vessels. It has always been a mainstream reliable model for medium and large plastic product factories pursuing stable output and low maintenance costs.

This machine adopts an upgraded large-volume accumulator head structure, which supports fast and uniform plastic extrusion and stable parison discharging. Compared with traditional continuous extrusion structures, the accumulator head design provides stronger melt plasticizing capacity, more uniform material fluidity and better molding consistency, which is extremely suitable for super-large hollow products with large material demand and high wall thickness uniformity requirements. The optimized internal runner effectively avoids material stagnation and plastic degradation, ensuring each molded water tank features smooth surface, no material lines, no bubbles and uniform overall texture.

Equipped with a high-precision servo wall thickness control system, the equipment realizes multi-point automatic correction of parison wall thickness during the molding process. The system can accurately adjust the material output of each section in real time according to product structure, effectively solving common molding problems such as uneven wall thickness, local thin points and product deformation. The finished 4000L water tank maintains stable wall thickness throughout the barrel body, bottom and top, greatly improving tank pressure resistance, impact resistance and overall structural durability. All finished products achieve high tightness and strong load-bearing performance after molding, meeting long-term outdoor use and harsh working environment requirements.

In terms of mechanical configuration, the whole machine adopts thickened welded frame and high-rigidity clamping mechanism, which effectively reduces vibration and deformation during long-term high-load operation. The upgraded hydraulic system provides stable clamping force and fast response speed, realizing rapid mold opening and closing while ensuring precise mold locking, preventing flash and edge burrs on products. The whole production process is highly automated, with intelligent touch screen operation, simple parameter setting, real-time operation data monitoring and automatic fault prompting, which greatly reduces manual operation difficulty and improves production efficiency.

In terms of safety and quality control, every Huayu 4000L blow molding machine undergoes strict no-load operation test, continuous belt material test and long-time stability inspection before delivery. All running parameters and molding effects are fully recorded and verified to ensure zero hidden dangers before leaving the factory. With reliable performance, low energy consumption, stable operation and long service life, this equipment helps customers achieve high-yield and high-quality production of large plastic water tanks, bringing stable and long-term economic benefits for manufacturing enterprises.
