The production line mainly uses PE (Polyethylene) and POE (Polyolefin Elastomer) as the core raw materials, combined with modified calcium carbonate filler. This material system provides excellent flexibility, tear resistance and mechanical strength, ensuring high-performance acoustic insulation products.
Composite Layer Materials
The composite structure adopts a three-layer configuration of non-woven fabric + PA barrier film + felt fabric. The non-woven fabric/felt fabric and PA barrier film are supplied by customers, providing flexibility and convenience in material sourcing and supply management.
Production Supporting Requirements
Circulating Cooling Water
• Inlet water temperature: ≤30°C
• Pressure: 4–6 bar
• Flow rate: 30–35 m³/h
A stable cooling system is essential for maintaining constant mold temperature, ensuring forming accuracy and guaranteeing continuous production stability.
Clean Compressed Air
• Pressure: ≥7 bar
• Flow rate: 0.9 m³/min
The compressed air supply should be treated by an air dryer and precision filtration system to ensure air quality is water-free, oil-free and dust-free, preventing contamination of raw materials and finished products.
Material Characteristics and Process Advantages
The production process adopts co-extrusion of PE/POE with calcium carbonate filler, combined with a thermal lamination process to integrate non-woven fabric and PA barrier film layers.
The final product combines excellent flexibility, breathability and superior barrier performance, fully meeting automotive material safety requirements and providing a reliable foundation for consistent product quality.
Production Line Process Flow and Layout
Detailed Introduction of Core Systems and Components
52:1 High Length-to-Diameter Ratio
The ultra-long L/D ratio design provides longer material residence time and more intensive shearing, effectively eliminating uneven plasticization and ensuring stable, high-quality melt performance.
Alloy Wear-Resistant Components
The screw elements and barrel liners are manufactured from imported high-strength alloy materials and undergo special hardening treatment, achieving a hardness of HV900+, ensuring excellent durability and long service life.
Intelligent Precision Temperature Control
The cast copper heaters provide rapid thermal response. Combined with an independent closed-loop water cooling system, they achieve temperature control accuracy within ±1℃, perfectly adapting to various heat-sensitive materials.
High-Efficiency Vacuum Degassing
The dual-stage powerful vacuum degassing system effectively removes moisture and low-molecular-weight volatiles, eliminates bubbles, and significantly improves product surface gloss and overall quality.
