Heavy-Duty 10000L 3-Layer Co-extrusion Blow Molding Machine and Blow Moulding

The Huayu 10000L 3-Layer Co-extrusion Blow Molding Machine is a heavy-duty, large-scale industrial blow molding equipment designed for ultra-large hollow plastic container production. It is professionally developed for manufacturing 10000L large-capacity HDPE water storage tanks, industrial liquid storage containers, environmental protection water treatment tanks and other high-standard large-volume plastic products. As a high-end three-layer co-extrusion molding device, it perfectly balances structural strength, barrier performance and production efficiency, becoming premium core equipment for large plastic container manufacturers worldwide.

Different from single-layer blow molding equipment, this machine adopts advanced three-layer co-extrusion integrated molding technology, realizing synchronous extrusion and one-time molding of inner, middle and outer material layers. Each layer undertakes independent functional responsibilities: the inner layer uses high-purity food-grade or chemical-resistant raw materials to ensure sanitation and corrosion resistance for stored liquid; the middle layer enhances overall structural rigidity and anti-aging performance, effectively improving pressure resistance and impact resistance of the tank body; the outer layer provides excellent weather resistance, preventing oxidation, ultraviolet damage and surface wear during long-term outdoor service.

Equipped with a high-capacity accumulator die head system, the equipment achieves rapid and uniform melt storage and extrusion. It thoroughly solves common molding defects of ultra-large containers such as parison sagging, uneven wall thickness and incomplete filling. The upgraded high-power extrusion system ensures sufficient plasticizing capacity for large-volume production, making plastic melt more uniform and stable, and greatly improving the overall molding consistency of finished tanks.

The machine adopts a highly reliable PLC intelligent control system and precise hydraulic drive system, supporting accurate parameter adjustment of extrusion volume, wall thickness distribution, blowing pressure, mold clamping stroke and cooling time. The multi-point wall thickness control technology realizes segmented precise thickness setting for different parts of the tank body, ensuring uniform wall thickness distribution and stable product quality. All production parameters can be stored and called with one click, realizing standardized, automated and batch intelligent production.

In terms of structural design, the whole machine adopts thickened heavy-duty steel frame and high-rigidity mechanical components, with strong shock resistance and operational stability. The optimized large-tonnage clamping structure provides powerful and balanced locking force, effectively avoiding mold expansion, flash and product deformation during high-pressure blowing. The efficient circulating cooling system greatly shortens the molding cycle, reduces unit energy consumption, and significantly improves continuous production capacity.

With superior structural design, stable operation and excellent finished product quality, the Huayu 10000L 3-layer blow molding machine meets the strict production standards of industrial storage, domestic water storage and environmental protection engineering. It features low failure rate, easy maintenance and long service life, and is the ideal high-efficiency molding solution for ultra-large plastic container mass production.
