Plastic is a popular raw material in a variety of manufacturing industries because it is cheap and versatile. There are many plastic products such as PVC window & door profiles, door panels window frames, which wouldn’t be possible without the plastic profile extrusion process.

Profile extrusion is the process of creating continuous shapes of plastic through extrusion, and plastic products produced by profile extrusion can be solid or hollow.

The profile extrusion process resembles the process of other extrusion methods up until the die is introduced. First, raw plastic materials are fed into a hopper and extruder. A rotating screw keeps the plastic resin moving through the heated barrel, which is set to the material’s specific melting temperature. Once the resin is melted, mixed, and filtered, the plastic will be fed into the extrusion mould and the extruded profiles will pass through the cold cutting and shaping table and through the tractor cutter to be cut to the set length.

Our profile production line includes conical/parallel twin screw extruder, profile extrusion mould, vacuum calibration table, hauler, cutter, stacker. The production line can be equipped with suitable screws according to the customer's formulation requirements to achieve the best plasticizing capacity. The line has the advantages of high efficiency, energy saving and high cost-effectiveness.
