A thermoplastic polyurethane elastomer rubber extruder

technical field

The utility model relates to the technical field of thermoplastic polyurethane elastomer rubber extruders, in particular to a thermoplastic polyurethane elastomer rubber extruder.

Background technique

Extruder is one of the types of plastic machinery. It originated in the 18th century. According to the flow direction of the head and the angle between the centerline of the screw, the extruder can divide the head into a right-angle head and an oblique head. The extruder relies on the pressure and shear force generated by the rotation of the screw, which can make the material fully plasticized and evenly mixed. Through the die molding, the plastic extruder can be basically classified into twin-screw extruder, single-screw extruder Extruders and rare multi-screw extruders and screwless extruders.
