In the Plastic Product Extrusion Line, the plastic extruder is usually called
the main machine, and the subsequent equipment, the plastic extrusion molding
machine, is called the auxiliary machine. After more than 100 years of
development, the plastic extruder has been derived from the original
single-screw, multiple-screw, multi-screw, and even non-screw models. The
plastic extruder (host) can be used with various plastic forming auxiliary
machines such as pipe, film, holding material, monofilament, flat wire, packing
belt, extruded net, plate (sheet) material, profiled material, granulation,
cable coating, etc. Matching to form various plastic extrusion molding
production lines to produce various plastic products. Therefore, plastic
extrusion molding machinery is one of the widely used models in the plastic
processing industry, no matter now or in the future. We learned about the
forming principle of plastic extruder from the Plastic Product Extrusion Line
Supplier, let's take a look.
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. Extrusion molding requires a deep understanding of plastic characteristics 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 passed through a die in a flowing state by heating and pressing in an extruder, also known as "extrusion". Compared with other molding methods, it has the advantages of high efficiency and low unit cost.
Plastic Product Extrusion Line Manufacturer pointed out that the extrusion method is mainly used for the molding of thermoplastics, but also for certain 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 mixing, plasticizing, granulating, coloring and blending of plastics.
The extruded product can be called "profile" because the cross-sectional shape is mostly irregular, it is also called "profile".
