Plastic Extruder can be called the host in the plastic extrusion equipment. Other subsequent mating devices are the assistants. After more than one hundred year's development, the plastic extruders have changed models from the original single screw into the modern twin screw, even multi screw.
Plastic Extruder can be matched with tube material, monofilament, flat, packing rope, and sheet material, profile, etc, to compose of a variety of plastic extrusion production lines. So from this point, we can find that the plastic extruder will get wide application in the field of plastic processing industry.
Plastic extruder machine consists of three systems, which are the extruding system, transmission system and the heating and cooling system.
The extruding system of the plastic extruder is made up of screw, barrel, hopper, nose and mold. Plastic subject goes through the extrusion system and will be plasticized to turn into a kind of homogeneous melts.
The screw stem is the main part of the plastic extruder, because it has close relationship with the extruder's application scale and production efficiency. Generally, the plastic extruder’s screw stem is made of alloy steel with high performance of corrosion-resisting.
