2500L 5-Layer Co-extrusion IBC Blow Molding Machine with 750kg/h Plasticizing Capacity for Large Industrial Containers

The HUAYU 2500L 5-Layer Co-extrusion Blow Molding Machine is a high-grade, large-scale hollow molding equipment developed for the manufacturing of 2500-liter industrial plastic tanks and heavy-duty hollow plastic products. Optimized for large-volume container production, this machine adopts advanced five-layer co-extrusion technology and integrated mechanical-hydraulic-intelligent control design, delivering exceptional stability, high molding precision, and outstanding cost-performance. It serves as a core production device for enterprises engaged in chemical packaging, environmental protection water storage, industrial liquid containment, and large plastic container manufacturing.

The five-layer composite co-extrusion structure stands as the most competitive feature of this equipment. Unlike conventional single-layer and three-layer blow molding devices, the multi-layer structural design realizes functional layering of different plastic materials. The inner food-grade and corrosion-resistant layer guarantees safe storage of drinking water, chemical reagents, and industrial liquids. The middle high-barrier layer effectively blocks oxygen penetration, moisture infiltration, and chemical erosion, drastically improving the anti-permeability performance of finished containers. The outer high-toughness structural layer provides excellent anti-aging, anti-collision, and weather resistance for long-term outdoor and industrial environment use. Meanwhile, the middle recycled material layer allows reasonable blending of qualified regrind materials, greatly lowering raw material costs while maintaining product quality stability and achieving green and low-carbon production.

Equipped with a large-capacity accumulator die head system, the machine ensures uniform plastic melting and stable parison extrusion for super-large 2500L products. The optimized flow channel design eliminates material dead angles and melting inconsistencies, ensuring smooth and continuous parison output. Matched with an independent high-precision wall thickness control system, the equipment supports multi-point dynamic adjustment in all directions. It effectively solves the common problems of uneven wall thickness, local thin points, and structural deformation of large containers, enabling finished products to feature uniform stress distribution and strong overall structural rigidity.

In terms of power and control system configuration, the machine adopts a mature energy-saving hydraulic drive system. It outputs stable and powerful clamping force and extrusion power, adapting to the high-load molding requirements of large-volume products. The hydraulic system is equipped with intelligent pressure regulation and flow control modules, which reduce unnecessary energy consumption during standby and operation, realizing significant energy-saving effects. The intuitive human-machine operation system integrates parameter storage, one-key automatic operation, automatic mold opening and closing, and automatic blowing and deflashing functions. The highly automated production process minimizes manual intervention, reduces human errors, and improves production efficiency and finished product yield.

The equipment features a robust and durable mechanical structure. The main frame adopts thickened high-strength steel plate welding and integral stress relief treatment, ensuring rigid body stability and no deformation during long-term high-frequency operation. Key transmission parts and molding components are made of high-quality alloy materials and processed with precision craftsmanship, effectively reducing component wear and failure probability and extending the overall service life of the machine. Complete safety protection mechanisms including overload protection, emergency stop device, and mold locking protection ensure safe and orderly operation in industrial production scenarios.

Widely applicable to the production of 2500L large chemical storage tanks, purified water storage tanks, sewage treatment tanks, and industrial buffer tanks, the HUAYU 2500L five-layer blow molding machine balances high barrier performance, structural durability, and production economy. With reliable operation, flexible material matching, and low operating cost, it has become a preferred high-efficiency molding solution for medium and large plastic container manufacturers worldwide.
