Principle of plastic extrusion

release date:2021-10-25 00:00 source: http://www.dfwpreppers.com Click:

The extrusion method of plastic extruder generally refers to melting the plastic at a high temperature of about 200 degrees, and the melted plastic forms the required shape when it passes through the mold. Dalian extrusion molding requires a deep understanding of plastic characteristics and rich experience in mold design. It is a molding method with high technical requirements.


Extrusion molding is a method in which materials are continuously formed through the die in a flowing state by heating and pressurizing in the extruder, also known as "extrusion". Compared with other molding methods, it has the advantages of high efficiency and low unit cost.


Extrusion method is mainly used for the molding of thermoplastics, and can also be used for some thermosetting plastics. The 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, plasticizing granulation, coloring, blending, etc.


The extruded product can be called "profile", which is also called "profile" because the cross-section shape is mostly irregular.


Dalian extrusion molding


Most of the raw materials are not particles for injection molding, but plastic powder. The formed plastic just coming out of the extrusion port has not been cooled and is easy to deform. Therefore, in order to suppress the deformation, it is recycled after extrusion.


The bellows on the washing machine can also be made by extrusion. After extrusion, it is transported to Caterpillar by compressed air for molding. In addition, by designing extrusion holes, drilling holes inside and outside the die, rotating and pushing the internal and external dies away from each other, a grid shape can be formed.
