Pin-type cold-feed screw & barrel systems feature pins installed at specific positions in the barrel, which are inserted into the screw to enhance rubber mixing and plasticization, increase extrusion output, and improve the surface gloss and air-tightness of extruded profiles.

Vented cold-feed screw & barrel systems are designed to remove moisture, air, and low-molecular volatiles from the rubber compound. By vacuum venting, the extruded products are bubble-free with high cross-sectional density, making them especially suitable for compounds containing recycled rubber or ...

Designed primarily for extrusion of rubbers such as:
Butyl (IIR)
Nitrile (NBR)
Ethylene Propylene Diene (EPDM)
Acrylate (ACM)
Ethylene-Acrylic Rubber (AEM)

Silicone rubber (SIR) is a special, relatively soft rubber, primarily used for:
Silicone tubes
Silicone profiles / custom shapes
Catheters
Composite silicone products

Specifications: Φ150 – Φ250 mm
Designed to filter impurities from natural rubber, butyl rubber (IIR), EPDM, silicone rubber (SIR), and recycled rubber.
Equipped with a twin-feed system, allowing pelletized or chunked rubber to be fed smoothly, without the need for pre-extruded rubber strips.
