EPDM Sealing Strip Extruder: Technical Details and Selection Guide

EPDM (ethylene propylene diene monomer rubber) sealing strips are widely used in automotive, construction, rail transit and other industries. They are the preferred material for sealing solutions due to their excellent weather resistance, ozone resistance and elasticity. The EPDM sealing strip extruder is the core equipment for production of such products, requiring specialized design for material properties and process requirements.

Core Requirements of EPDM Sealing Strip Extruder

Material property adaptation: High-torque screws and forced feeding systems required due to EPDM's poor fluidity and high viscosity
Temperature sensitivity: Precise temperature control needed (optimal processing temperature: 80-120°C)
Process difficulties: Vacuum exhaust function required to remove entrained air; high-precision die and shaping device needed for complex cross-sections

Equipment Composition and Key Technologies

1. Extrusion System

Screw design: Length-to-diameter ratio (L/D) 18:1-22:1 with high compression ratio 1.8:1-2.5:1
Mixing section: Barrier screw or pin mixing section to ensure uniform plasticization
Barrel temperature control: Multi-stage PID control (±1℃ accuracy)

2. Feeding System

Forced feeding roller to prevent EPDM slipping
Optional premixing device for uniform dispersion of additives

3. Vacuum Exhaust System

Two-stage screw: first stage plasticization, second stage vacuum degassing (vacuum degree ≥ 0.08MPa)
Effective bubble removal to reduce internal defects

4. Die Head and Die

Gradient flow channel design to avoid dead glue and adapt to complex cross-sections
Chrome-plated or high-strength alloy steel construction for wear resistance

5. Auxiliary Equipment

Segmented cooling water tank (60℃→room temperature) to prevent deformation
Servo motor driven traction machine with speed synchronization accuracy ±0.5%
Laser length measurement for fixed length cutting or automatic coiling
