Cold-Feed Rubber Extruder | Pin-Barrel & Vent-Type LN-E Series for Tire, Hose & Profile Production

Cold-Feed Rubber Extruder – Brief Introduction

A cold-feed rubber extruder (also called rubber cold-feed extruding machine, pin-barrel cold-feed extruder, vent-type cold-feed extruder, or cold-feed rubber block extruder) accepts rubber compound at ambient temperature. Through screw shearing, compression and precise temperature control, it realizes low-temperature plasticizing, degassing and continuous extrusion without pre-heating. Compared with traditional hot-feed systems, it eliminates warm-up mills, cuts energy consumption by 20–35 %, keeps stock temperature low and minimizes scorch risk, making it the core equipment for efficient production of tires, hoses, sealing strips, cables and other rubber products.

Guangdong LiNa LN-E Series Cold-Feed Rubber Extruder

—— 45 mm – 200 mm Full-Spec High-Plasticizing Solution

1. Key Features  

1. High-compression-ratio screw

   Patented wave-type + BM barrier design, compression ratio 2.4–2.8, full plasticizing at low temperature, reduced scorch.  

2. Pin-type shearing zone (optional)

   8–12 rows of radial pins, dispersion improved by 15–25 %, ideal for high carbon-black loading.  

3. Smart temperature control

   4–6 zones PID ceramic heaters + closed-loop water cooling, ±2 °C accuracy, 15 min heat-up.  

4. Inverter + hardened-gear reducer

   ABB/Siemens inverter, transmission efficiency ≥ 96 %, noise ≤ 78 dB(A).  

5. Quick screen changer & self-cleaning

   Hydraulic slide screen change ≤ 3 min; bidirectional mixing head prevents compound build-up.  

6. Modular die head

   Fast switch between sheet, tube or profile dies, supports flexible multi-product manufacturing.

2. Models & Output  

Actual output depends on compound hardness and formulation.
