High-Performance Rubber Extruder Machine for Cold & Hot Feed Extrusion

Core Technical Features

• Screw & Barrel Material: High-quality 38CrMoAlA alloy steel, treated with nitriding, ensuring high wear resistance and a long service life.

• Temperature Control System: Multi-zone independent water or oil circulation cooling systems to ensure precise temperature control and prevent scorching (vulcanization) during the extrusion process.

• Drive System: Heavy-duty AC motors with frequency inverters (VFD) for smooth speed adjustment and energy savings.

• Pin Barrel Technology (Optional): For cold feed extrusion, the pin barrel design improves the plasticizing effect, reduces the extrusion temperature, and increases the output by up to 50% compared to standard extruders.

• Extrusion Heads (Dies): Custom-designed extrusion heads are available to produce specific profiles, such as tire treads, sidewalls, hoses, or flat sheets.

Applications (Where It Can Be Used)

• Tire Industry: Extruding tire treads, sidewalls, apex, and inner liners.

• Automotive & Industrial Hoses: Manufacturing inner tubes, outer covers, and reinforcing layers.

• Sealing & Profiles: Extruding weather strips, window seals, and custom rubber shapes.

• Cable & Wire: Extruding insulation and jacketing layers.

• Rubber Sheets & Mats: Producing continuous flat sheets, conveyor belt covers, and waterproof membranes.

FAQ (Frequently Asked Questions)

Q1: What is the difference between a cold feed and a hot feed rubber extruder?
A: A cold feed extruder directly processes raw, unheated rubber compound, saving the cost of a warming mill. A hot feed extruder requires pre-warmed (hot) rubber strips, usually offering higher output but requiring more equipment and labor.

Q2: Can you customize the extrusion head (die) for my specific product?
A: Yes, we have a strong R&D team that can design and manufacture custom extrusion heads based on your product cross-section drawings.

Q3: How do you control the temperature during extrusion?
A: We use multi-zone cooling systems (water or oil) combined with precise temperature sensors. For cold feed extrusion, the pin-barrel design also helps dissipate heat from the rubber compound.
