What is extrusion molding?
Extrusion molding in the plastic processing process is also known as flame retardant plastic, in the production of the use of four-column hydraulic press working pressure on the grinding tool itself extrusion weigh pressed out. It refers to a processing process in which raw materials are thermoplasticized and pushed forward by the screw according to the efficacy between the extruder barrel and the screw, and are successively made into a variety of cross-sectional products and semi-products according to the engine. Extrusion molding is a kind of high efficiency, continuous, cost reduction, into the opening of the forming process, is a technology occurred earlier in the processing of fiber materials, extrusion molding is a high polymer production and processing field in the production of more types of manufacturing, more changes, high production efficiency, strong adaptability, widely used, the proportion of the largest molding processing process. Extrusion molding is one of the most important forms of heat treatment of plastic materials, it is suitable for most plastic raw materials except some thermosetting plastic plastics, about 50% of thermosetting plastic plastic products are completed by extrusion molding, at the same time, many are used to form synthetic fibers and thermoplastic rubber and plastic products; Extrusion molding can produce pipe fittings, bar material, plastic plate, plastic profile, cable cable sheath, wire drawing and other forms of continuous variable commodities.



Advantages of extrusion processing technology

1. Manufacturing Continuous production
According to the actual situation, we can manufacture pipe fittings, plate, bar, plastic profile, plastic film, cable and wire drawing.

2. High work efficiency
Extruder equipment single version production is relatively high

3. Wide range of application
This kind of processing technology is widely used in the production and processing of plastics, plastics, fabrics, especially plastic products, it seems that most of the thermosetting plastics and some thermosetting plastics can be produced and processed by this method. Except for immediately formed products. It can also be used by extrusion method for mixing, melting, granulation, coloring, molding and so on

4. Multiple use of one machine
An extruder can produce a variety of raw materials and various products. Different products can be produced by disassembling different types of screws and engines according to the functional characteristics of raw materials and the shape and specifications of the products.

5. Simple machinery and equipment, low investment
Compared with injection molding and injection molding, extrusion machinery and equipment are very simple, production and manufacturing are relatively easy, the cost of machinery and equipment is relatively low, and the installation and debugging of equipment is convenient. The machinery and equipment covers a small area, and the requirements for industrial plants and supporting facilities are relatively simple.
