Huayu 1500L 5-Layer Co-extrusion Fully Automatic Blow Molding Machine for HDPE

The Huayu 1500L 5-Layer Co-extrusion Blow Molding Machine is a high-end, fully automatic hollow plastic molding equipment independently developed for large-capacity industrial container production. Tailored for manufacturing 1500-liter large-scale plastic tanks, IBC totes, and chemical storage containers, this machine integrates advanced five-layer co-extrusion technology to break through the performance limitations of traditional single and three-layer blow molding equipment. It delivers superior barrier performance, structural stability, and production consistency, making it an ideal solution for medium and high-end plastic container manufacturing industries worldwide.

The core advantage of this equipment lies in its professional five-layer co-extrusion structural design. Different functional polymer materials are extruded and compounded in one molding cycle, forming a composite container wall with distinct functional layers. The outer layer adopts high-rigidity HDPE material to ensure excellent impact resistance, wear resistance, and outdoor aging resistance, enabling finished containers to adapt to complex storage and transportation environments. The middle functional barrier layer uses high-performance barrier materials such as EVOH and PA, which effectively isolate gas, moisture, and chemical corrosion. This greatly reduces the permeability of volatile liquids and solves the common problems of container deterioration, liquid volatilization, and short service life of ordinary single-layer plastic tanks. The inner food-grade and chemical-resistant layer ensures safe storage of drinking water, chemical reagents, and industrial raw materials, meeting diverse industrial application standards.

Equipped with a precision servo parison control system, the machine achieves real-time dynamic adjustment of parison wall thickness. The intelligent thickness calibration technology ensures uniform wall thickness of 1500L large containers, effectively avoiding defective products caused by uneven stress and local thin walls. The optimized accumulator extrusion system provides stable and sufficient material supply, realizing high-speed and consistent extrusion of large-volume plastic parisons. The upgraded die head structure adopts high-precision polishing and self-cleaning design, ensuring smooth material flow without dead angles, reducing material residue, and lowering mold cleaning and maintenance frequency. All mechanical transmission parts are made of high-strength alloy materials, with wear resistance and fatigue resistance greatly improved, supporting long-term uninterrupted industrial operation.

This blow molding machine features a highly integrated fully automatic production process, covering automatic material feeding, melting extrusion, parison forming, mold clamping, blow molding, cooling shaping, and product demolding. The entire production process requires minimal manual intervention, effectively improving production efficiency and reducing labor costs. The intelligent control panel supports parameter memory and one-key start-up, which is convenient for staff operation and production management. The professional water circulation cooling system realizes rapid and uniform cooling of large containers, shortening molding cycle time, improving product shaping efficiency, and ensuring stable product dimensional accuracy and surface flatness.

In terms of safety and energy saving, the equipment is equipped with multiple safety protection mechanisms, including overpressure protection, overload stop, and mold safety locking devices, which eliminate potential safety hazards during high-load operation. The optimized power operation mode reduces invalid energy consumption during equipment standby and operation, achieving efficient and energy-saving production. Compared with traditional large blow molding machines, it has lower operating costs and higher production yield.

Widely applicable in chemical industry, environmental protection water treatment, food storage, industrial logistics and other fields, the Huayu 1500L 5-layer blow molding machine can stably produce high-standard 1500L large barrier plastic containers. With reliable quality, stable performance and excellent after-sales support, it has won wide recognition from global customers and becomes a reliable high-efficiency production equipment for large plastic container manufacturers.
