The principle of extrusion molding of plastic extruder

Plastic extruder is one of the most widely used mechanical equipment in the plastic processing industry, used to produce various plastic products. Next, Camel Machinery will introduce the extrusion molding principles of plastic extruders and small extruders.

The 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 is passed through the mold to form the desired shape. The extrusion molding of plastic extruder requires a deep understanding of plastic characteristics and rich experience in mold design, and it is a molding method with high technical requirements.

"Extrusion molding is a method in which materials are continuously passed through a die in a flowing state by heating and pressurizing in a plastic 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.

The products extruded by the plastic extruder 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, blending, etc. of plastics. The products extruded by extruder can be called "profiles".
