The plastic extruder generally melts the plastic powder at a high temperature in the heating section, and the melted plastic forms the required shape when it passes through the mold, and then completes the production of a product through subsequent mold accessories. Extrusion molding has high requirements on various control of equipment, including speed control, temperature control, etc. Engineers need to have a deep understanding of plastic properties and rich experience in mold design, which is a molding method with high technical requirements.

Extrusion molding is a method in which materials are continuously formed through a die in a flowing state by heating and pressurizing in an extruder, also known as "extrusion". Compared with other molding methods, it has the advantages of high efficiency and low unit cost. The extrusion method is mainly used for the molding of thermoplastics, and can also be used for some thermosetting 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 mixing, plasticizing, granulating, coloring, and blending of plastics. The extruded products include "pipes", "profiles", etc. Since most of the cross-sectional shapes of the pipes are irregular, they are also called "profiles".

After more than 100 years of development, plastic extruders have been derived from the original single-screw, twin-screw, multi-screw, and even no-screw models. Plastic extruder can be used with various plastic forming auxiliary machines such as pipe, film, holding material, monofilament, flat wire, packing belt, extruding mesh, plate (sheet) material, profiled material, granulation, cable coating and so on. Match to form various plastic extrusion molding production lines to produce various plastic products.Therefore, Forming machine is one of the widely used models in the plastic processing industry, now or in the future.
