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 other complex raw materials.

Applications:

Extrusion of shaped sealing strips

EPDM foam products

Other rubber profiles requiring high-density, defect-free extrusion

Specifications:

Diameter: Φ45mm – Φ200mm

L/D Ratio: 1:16 – 1:20
