The?plastic pipe extrusion method of the plastic extruder generally refers to the melting of the plastic at a high temperature of about 200 degrees, and the molten plastic passes through the mold to form the desired shape. Extrusion requires a deep understanding of the characteristics of plastic and mold design experience, is a high technical requirements of the molding method.
Extrusion molding is in the extruder by heating, pressure leaving the material in a continuous state through the die forming method, also known as “extrusion.” Compared with other molding methods, it has the advantages of high efficiency and low unit cost.

Extrusion is mainly used for the molding of thermoplastics, can also be used for some thermosetting plastics. Extruded products are continuous profiles, such as tubes, rods, wires, plates, films, wire and cable cladding. In addition, can also be used for plastic mixing, plastic granulation, coloring, blending and so on.
Extruded products can be called “profiles”, because the cross-sectional shape of most irregular, so called “profile”.
