Pin Free Extruder Screw Barrel

Rubber Extruder Screw: Its function is to make the rubber material gradually become linear movement with the screw rotation movement, approaching to the direction of the head, and matching with the machine body to complete compression heat, softening mixing, and mixing rubber material.

Rubber Extruder Barrel: Containing screw rotating in the barrel. When the screw rotates the thread to push the extruded material to move forward, the external heating conducts heat to the material by the cylinder, coupled with the gradual reduction of the screw volume, making the material suffer several force such as extrusion, turnover and shear, finally the material is evenly mixed and plasticized into molten viscous flow to complete the plasticizing work.

The screw and barrel of the pin free extruder are used together. During the working process, the glue can interact with the screw on the inner wall of the barrel to ensure that the glue is mixed and moved under pressure, as well as play a role of heat exchange.

The company specializes in providing customized processing of cold and hot feed extruder screw barrel for various purposes, which is widely used for extruding various rubber products and providing glue for calender. It can also be used for encapsulating and filtration of rubber impurities of tire surface, inner tube, cable, wire, film, and rubber hose.
