Huayu 4000L 4-Layer Co-Extrusion Accumulator Blow Molding Machine

The Huayu 4000L 4-Layer Co-Extrusion Accumulator Blow Moulding Machine is a high-performance, large-scale hollow plastic molding equipment independently developed for the mass production of 4000-liter large-capacity HDPE water storage tanks, industrial chemical storage tanks, and multi-functional plastic container products. Tailored for the high-standard production demands of large plastic containers in chemical industry, water conservancy storage, outdoor engineering and industrial packaging fields, this equipment integrates mature co-extrusion technology, precise molding control and durable mechanical structure, and has become a core preferred device for medium and large-sized plastic container manufacturers worldwide.

The machine adopts advanced four-layer co-extrusion molding technology, which realizes the synchronous extrusion and one-piece molding of four different functional material layers. Compared with traditional single-layer blow molding equipment, the multi-layer structural design endows plastic tanks with more diverse and stable performance. The inner layer adopts high-purity food-grade or chemical-resistant raw materials to ensure the safety of stored water, liquid chemicals and other media; the middle structural layer uses high-strength modified plastic materials or recycled plastic materials reasonably, which effectively enhances the overall rigidity and impact resistance of the container while reducing production costs; the outer functional layer is optimized with anti-ultraviolet and anti-aging formulas, enabling the finished tanks to adapt to long-term outdoor exposure, high temperature, low temperature and harsh weather environments, avoiding cracking, fading and permeability failure.

Equipped with a high-precision digital wall thickness control system and intelligent hydraulic drive system, the equipment achieves full-process precise adjustment of parison extrusion. It supports multi-point uniform thickness calibration in all directions of the container, thoroughly solving the common problems of uneven wall thickness, local thinness and product deformation of large blow-molded containers. The optimized large-capacity accumulator head is professionally matched with the molding demand of 4000L super-large containers, realizing stable plasticization, uniform feeding and continuous extrusion. The whole molding process is stable and efficient, effectively improving the yield of finished products and reducing the waste of raw materials, bringing significant cost advantages for long-term mass production.

In terms of operation and configuration, the machine is equipped with a humanized intelligent touch control system, with visualized parameter setting, one-key start-stop operation and real-time operating data monitoring functions. The system supports independent adjustment of extrusion speed, molding pressure, cooling time and layer proportion parameters, which can flexibly adapt to different mold specifications, material formulas and production process requirements. The fully automatic production process greatly reduces manual intervention, lowers the threshold of operation and labor costs. Meanwhile, the equipment adopts an integrated modular structural design, with compact overall layout, good mechanical stability and strong shock resistance, which can maintain long-term stable continuous operation without frequent failure.

In terms of durability and after-sales adaptability, all core mechanical components are made of high-strength alloy materials and processed by precision technology, with strong wear resistance and fatigue resistance. The heat dissipation and cooling system are fully optimized to ensure rapid and uniform cooling of products and improve molding efficiency. The equipment supports personalized customization according to customer production needs, including mold matching, production capacity adjustment and functional module upgrading. With stable performance, simple daily maintenance and long service life, this 4000L four-layer blow moulding machine provides reliable, efficient and cost-effective professional molding solutions for the large plastic container manufacturing industry.
