Automotive Acoustic Insulation Pad Extrusion Machine Line |JWELL PE EVA POE Composite Line

Equipment Overview and Application Areas

This production line is a highly integrated automated system specially designed for manufacturing high-quality automotive interior components.

By integrating extrusion, lamination, forming and cutting technologies, the line efficiently processes PE, POE and calcium carbonate filled materials to produce interior materials with excellent sound insulation, thermal insulation and cushioning performance, ensuring high production efficiency and stable operation.

Key Material Features:

Adopting a one-step formulation and forming process, the system allows flexible adjustment of material formulations while maintaining stable performance across a wide temperature range from -40°C to 120°C. With lightweight characteristics and high toughness, the material is an ideal solution for achieving energy saving, emission reduction, noise reduction and enhanced driving comfort in automotive applications.

Technical Specifications and Key Parameters

Core Raw Material System

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.
