What is plastic extruder?

In the plastic extrusion molding equipment, the plastic extruder is usually called the main machine, and the subsequent equipment that is matched with 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, multi-screw, and even non-screw and other models. The plastic extruder (host) can be used with various plastic molding auxiliary machines such as pipe, film, holding material, monofilament, flat wire, strapping, extruding net, board (sheet) material, profiled material, pelletizing, 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, whether it is now or in the future.

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 pressurizing in an 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 extruded products are all 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 extruded product can be called "profile", because the cross-sectional shape is mostly irregular, it is also called "profile".

Extrusion,has high material utilization, improved material organization and mechanical properties, simple operation, high productivity, and can produce long rods, deep holes, thin-walled, and special-shaped cross-section parts. It is important to avoid cutting. Processing technology.

What is plastic extrusion used for?

Extrusion is mainly used for the forming of metals, but also for the forming of non-metals such as plastics, rubber, graphite and clay blanks. In the 17th century, the French used a manual screw press to extrude the lead pipe and used it as a water pipe, which was the beginning of cold extrusion.

The extrusion molding process is widely used in the processing of rubber, plastics, and fibers.

1. The more prominent feature of the extruder is the continuous production. It can produce any length of pipe, plate, bar, profile, film, cable and monofilament according to the needs.

2. Not only the production efficiency is high, but the single extruder output is also high. If it is an extruder with a diameter of 65mm to produce polyvinyl chloride film, the annual output can reach 450t or more.

3. Extrusion molding technology has a wide range of applications, whether it is used in rubber, plastic, fiber and other related processing, especially in the production of plastic products. Most thermoplastics and some thermosetting plastics can be processed by this method. In addition to direct molding products, extrusion methods can also be used for mixing, plasticizing, pelletizing, coloring, blank molding and other processes. If an extruder is matched with a calender, it can also be used to produce calendered films; when matched with a press, it can produce various press-formed parts; when matched with a blow molding machine, it can produce hollow products. In the production process of rubber products, the extrusion method is used to manufacture treads, inner tubes, hoses, and various products with complex cross-sectional shapes and semi-finished products such as hollow, solid, and encapsulated rubber products. It can also be used for continuous mixing of rubber and raw rubber. Plastic refining and granulation applications. In the petrochemical plant, during the resin production process, an extruder can be used to squeeze to remove the moisture in the resin, and the extruder can be used to complete the mixing of additives and modifiers in various grades of resin to complete the resin granulation process.

4. Compared with the injection molding machine calender, the extrusion molding process equipment is simpler, the investment is less, the manufacturing process is relatively low, the equipment cost is lower, the installation and commissioning process is more convenient, the floor space is small, and the requirements for the plant and supporting facilities are relatively simple
