The forming principle of plastic extruder:

We use a plastic extruder to produce the shape we need, which requires a deep understanding of the characteristics of the extruded plastic and rich design experience in the mold, and the extrusion method generally refers to the temperature at about 200 ° C. The plastic is melted at high temperature, and then the desired shape is produced through the mold, which is a molding method with relatively high technical requirements.

Extrusion molding is a method in which the material is continuously passed through the mold in a flowing state by heating and pressure in the extruder, called 'extrusion molding'. Compared with other molding methods, it has high efficiency and low unit cost. Advantage.
Extrusion is mainly used to produce thermoset plastics or some thermoset plastics. Extruded products are continuous profiles, such as tubes, rods, wires, plates, films, wire and cable coatings, etc. In addition, it can also be used for plastic mixing, melting granulation, coloring, mixing, etc.

Extruded products can be called 'profiles' because most of the cross-sectional shapes are irregular, so they are also called 'profiles'. This is the principle of plastic extruder molding;

Nanjing Tengda Machinery Co., Ltd. also discusses implications for both research and the practice of operations in building systems to help people succeed in both the short and long run.
