Plastic Extrusion Machinery

In Plastic Extrusion Machinery, plastic extruders are often referred to as mainframes, and the accompanying equipment plastic extrusion molding machines are called auxiliary machines. 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.
Plastic extruder (main machine) can be used with pipes, films, materials, monofilaments, flat yarns, packing belts, extruded nets, plates (sheets), profiles, granulation, cable coating, etc. Matching, forming a variety of plastic extrusion molding lines to produce a variety of plastic products. Therefore, plastic extrusion molding machines are one of the most widely used models in the plastics processing industry, now or in the future.
Plastic extruders can be divided into single screw extruders, twin screw extruders and multi-screw extruders according to the number of screws. At present, the single-screw extruder is the most widely used, and is suitable for extrusion processing of general materials. The twin-screw extruder has less heat generated by friction, the shearing of the material is relatively uniform, the conveying capacity of the screw is larger, the extrusion amount is relatively stable, the material stays long in the barrel, and the mixing is uniform.
Forming principle
The extrusion method of a plastic extruder generally refers to melting a plastic at a high temperature of about 200 degrees, and the molten plastic forms a desired shape when it passes through the mold. Extrusion molding requires a deep understanding of plastic properties and extensive experience in mold design, and is a highly technically demanding molding method.
Extrusion molding is a method in which a material is continuously passed through a die by a heating and pressurization in an extruder, which is also referred to as "extrusion". Compared with other molding methods, it has the advantages of high efficiency and low unit cost.
Extrusion is mainly used for the molding of thermoplastics and for some thermosets. Extrusion products are continuous profiles such as tubes, rods, wires, sheets, films, wire and cable coatings, and the like. In addition, it can also be used for mixing, plasticizing, granulating, coloring, blending, etc. of plastics.
Extrusion products can be called "profiles" and are also called "profiles" because they are mostly irregular in cross-sectional shape.
