Heavy-duty screw barrel designed for rubber extrusion and vulcanization processes. Heat-resistant materials, high torque, stable output for EPDM, silicone, and natural rubber.
Vanwell rubber screw barrels are engineered for the demanding requirements of rubber extrusion and vulcanization processes. Built with heat-resistant alloys and specialized flight geometry, our rubber screws handle the high viscosity and abrasive nature of uncured rubber compounds.
The screw design features a deep feed section for effective feeding of rubber batches, followed by a compression zone that ensures thorough plasticization and uniform vulcanization. Bimetal barrel linings and surface-hardened screws provide extended wear life even with highly filled rubber compounds containing carbon black, silica, or other reinforcements.
High-temperature resistant steel alloy for stable performance during vulcanization.
Robust screw shaft and deep flight design handle high viscosity rubber compounds.
Plasma nitriding surface treatment for extended life with carbon-black filled rubber.
Precisely machined flights ensure consistent rubber profile extrusion quality.
Wear-resistant barrel liner handles abrasive fillers and high-hardness compounds.
Large volume feed section for continuous rubber batch feeding without bridging.
Fits standard rubber extruders from small laboratory to large industrial production.
Stable performance at vulcanization temperatures up to 400°C.
