Classifications of plastic extruder

The development of plastic extruder is a long history. The machine in nowadays has a large demand. In order to meet the market demand, with the development of technology, plastic extruder has been developed to various kinds.

According to the quantity of screws, the plastic extruder can divided into single screw extruder, twin-screws extruder, multi-screws extruder and non-screws extruder and so on. The single screw plastic extruder is most extensively used at present; it is suiting in the extrusion processing of general materials. Twin-screws plastic extruder also has an important function in the market owing to its various advantages. The advantages of twin-screws extruder are followed: the quantity of heat caused by friction is less, the cut of materials is relatively uniform, the deliver ability of screw is large, the extrusion quantity is relatively stable, the stay time of materials in the cylinder is long and the mixing is uniform.

The single screw plastic extruder occupies an important place whether it is regarded as Plasticizing granulation machinery or Processing machinery. In recent years, single screw extruder has a large development. The twin-screws plastic extruder has the better funticons of mixing, exhausting and self-cleaning. On the basic of twin-screws extruder, the multi-screws plastic extruder is appeared in order to process the blending materials which has bad heat stability.

Different types of plastic extruder can meet different processing, to produce the plastic productions can meet the requirements.

Brief introduction of plastic extruder

Plastic extruder is the main machine of plastic extrusion equipment, and the follow-up support equipment plastic extrusion machine is called auxiliary. After the 100 years’ development, plastic extruder has developed from the single screw to twin-screw, multi-screw, even the non-screw and so on. The plastic extruder can match with various kinds of plastic molding auxiliaries, such as tubing, thin film, monofilament, flat filament, packing tape, extruded net, plate (sheet) material, profiled material, granulation, cable cladding and so on. All of the components mentioned above constitute various plastic extrusion production lines and produce various plastic productions. Therefore, plastic extruder will be a kind of machine which will be extensively used in plastic processing industry, whether in future or at present.

Plastic extruder came from the extruder. The extruder originated from 18th century. English Joseph Bramah made manual piston extruder which used for making seamless lead pipe in 1795. This extruder was regarded as the first extruder in the world. From then on, in the before 50 years of 19th century, the extruder was only used in the produce of lead pipe, the processing of macaroni and other food, the produce of brick and ceramics and so on. With the development, the extruder began to use in more and more areas, for example the plastic extruder which made the produce of plastic more and more convenient.
