The extrusion method of a plastic extruder generally refers to melting plastic at a high temperature of around 200 degrees, and the melted plastic forms the desired shape when passing through the mold. Extrusion molding requires a deep understanding of plastic properties and rich experience in mold design, and 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 molding. 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 thermoplastic plastics, and can also be used for certain thermosetting plastics. The extruded products are all continuous profiles, such as pipes, rods, wires, plates, films, wire and cable coatings, etc. In addition, it can also be used for mixing, plasticizing, granulating, coloring, blending, etc. of plastics.
The extruded product can be called a "profile", and due to the irregular cross-sectional shape, it is also called a "Heterogeneous profile".
