Plastic extruder extruding method generally refers to the high temperatures of around 200 degrees so that the plastic melting, molten plastic through the mold, forming the shape you need. Extrusion requires on the plastic characteristics of deep understanding and design experience, is a method of molding technology high requirements.
Extrusion is in the extruder by heating to continuous flow, pressure and make the material through the die molding method, also known as "plastic". Compared with other forming methods, has the advantages of high efficiency, low cost per unit.
Extrusion method is mainly used for molding of thermoplastic plastics, can also be used in thermosetting plastics. Extruded products are continuous profiles, such as tubes, rods, wire, plates, films, such as wire and cable coating. In addition, can also be used for plastic mixing, plastic pelletizing, colouring, mixed, etc.
Extrusion product can be called "profiles", because of the cross sectional shapes are irregular, so is also known as "profiles".
