Huayu 6000L 4‑Layer Accumulator‑Type Blow Molding Machine

Product Specification

The Huayu 6000L 4-Layer Water Tank Blow Molding Machine is a heavy-duty, fully automatic extrusion blow molding solution independently developed for large-capacity plastic water tank production. Adopting professional four-layer co-extrusion molding technology, this equipment achieves one-piece integral molding for 6000-liter large water storage tanks, widely applied in domestic water storage, rural water supply, factory water storage, and outdoor anti-corrosion storage scenarios.
Different from ordinary single-layer and double-layer blow molding equipment, the four-layer composite structure endows finished water tanks with more stable physical performance. Each material layer undertakes independent functional tasks. The outer layer adopts high-strength anti-aging formula materials to resist ultraviolet radiation, outdoor temperature changes and environmental erosion, effectively avoiding cracking, fading and embrittlement during long-term outdoor use. The middle composite layers enhance structural toughness and compression resistance, improving the overall bearing capacity and impact resistance of the tank body. The inner layer uses food-grade and high-purity raw materials to ensure clean and safe water storage, meeting daily domestic water and general industrial water storage standards.
This machine is equipped with an integrated multi-group independent extrusion system, which realizes stable feeding and uniform plasticization of four different raw materials simultaneously. The optimized co-extrusion die design ensures synchronous and balanced material output, effectively solving common problems such as uneven layer thickness, material mixing and partial material shortage in multi-layer products. It greatly improves the yield and appearance flatness of large water tanks.
The whole production process realizes full automatic operation from automatic feeding, constant-temperature plasticization, parison extrusion, mold clamping, blow molding, cooling shaping to final demolding. The intelligent constant temperature control system precisely adjusts the temperature of each extrusion zone to ensure thorough and uniform raw material plasticization and avoid carbonization or material deterioration. The high-precision wall thickness control system dynamically adjusts the parison thickness in real time, making the wall thickness of the 6000L large tank uniform with low tolerance, stable product consistency and fewer defective products.
Built with heavy-duty mechanical structure and high-standard industrial accessories, the equipment runs stably for a long time with low failure rate and long service life. It supports continuous 24-hour industrial batch production, effectively improving production efficiency and reducing manual operation costs. In addition, the equipment adopts energy-saving structural design, which reduces unnecessary power consumption while ensuring production capacity, helping manufacturers achieve efficient and low-cost production.
As a reliable large blow molding equipment made in China, Huayu 4-layer water tank blow molding machine focuses on practical industrial production needs, provides stable molding quality and perfect after-sales technical support, and has become the preferred equipment for many plastic tank manufacturers to upgrade their production lines.
