Cooling Channel Insert Component – Rubber and Plastic Product Manufacturing

Component Specifications

Definition

A cooling channel insert is a specialized component integrated into polymer extrusion barrel liners, designed to regulate barrel temperature through precisely machined internal cooling channels. It maintains optimal thermal conditions during extrusion processes by circulating coolant to prevent overheating, ensure consistent polymer viscosity, and improve product quality.

Working Principle

Operates by circulating a coolant (typically water or thermal oil) through internal channels to absorb heat from the barrel liner, maintaining a stable temperature profile along the extrusion zone to prevent polymer degradation and ensure consistent melt properties.

Materials

High thermal conductivity alloys: Copper alloys (C11000, C17200), Beryllium copper (C17200), Stainless steel (316L) with anti-corrosion coatings, Aluminum bronze (C95400)

Technical Parameters

Surface Finish Ra ≤ 0.8 μm
Channel Diameter 3-12 mm
Coolant Flow Rate 10-50 L/min
Temperature Range 20-200°C
Operating Pressure 3-8 bar
Thermal Conductivity ≥200 W/m·K

Standards

ISO 12100, DIN 2448, ISO 13709
