The pin‑type cold‑feed rubber extruder is suitable for extrusion molding of rubber hoses, inner tubes, tapes, sealing products, and other rubber goods. This type of extruder features pins mounted on the barrel, which engage with corresponding grooves on the screw. Thanks to the action of these pins, the pin‑type cold‑feed extruder offers advantages such as high output, low processing temperatures, reduced energy consumption, superior product uniformity, stable discharge, and minimal residual rubber left in the screw after shutdown. The introduction of the pin‑barrel cold‑feed extruder has significantly advanced and expanded the technology of cold‑feed extruders. This machine incorporates substantial improvements to the screw design, and the addition of pins to the barrel further enhances its performance.

The introduction of the pin‑bar barrel cold‑feed extruder has significantly advanced and expanded the technology of cold‑feed extrusion. This type of extruder features a substantially improved screw design, and the addition of pins to the barrel markedly enhances its plasticizing performance, the density of extruded products, and the extrusion output. Moreover, it operates at lower die temperatures, enabling it to meet the extrusion requirements of a wide range of production processes. At the same time, the optimized screw configuration reduces drive power and lowers specific energy consumption. Owing to its excellent plasticizing capability, low die temperature, and high extrusion capacity, it has found increasingly widespread application in the rubber industry.

Industry Use

It can be applied across various sectors of the rubber industry, including extrusion of semi‑finished rubber tire components, inner and outer extrusion of rubber hoses, adhesive supply for calendering equipment, extrusion of rubber products in diverse shapes, and filtration extrusion of reclaimed rubber, among others.

Key Features

The cold-feed extruder with a screw‑barrel design features a plasticization section, which is divided into a screw‑barrel zone and a conveying zone. In the screw‑barrel zone, the rubber compound undergoes a degree of plasticization before entering the conveying zone, where it achieves thorough mixing. This configuration enhances mixing and plasticization efficiency, boosts production capacity, and reduces temperature rise and energy consumption.
