At present, China's plastic extruder market is developing rapidly, and many new models have been launched. With the joint efforts of technology and R & D personnel in the industry, some main special machines such as exhaust extruder, series grinding disc screw extruder, reciprocating pin screw extruder, foam extruder, extruder with melt gear pump, series multi-stage extruder Planetary screw extruders are produced by domestic manufacturers, have the ability of independent research and development, and enjoy independent intellectual property rights

with the upgrading of technology, the era of manual feeding of plastic extruder equipment has long ended. People can be freed from the environment of heavy physical labor and flying dust. The work originally completed manually is now completed automatically by conveying equipment, which has made great contributions to the plastic industry

in recent years, people have done a lot of theoretical and Experimental Research on screws. So far, there are nearly 100 kinds of screws, including separation type, shear type, barrier type, shunt type and wavy type. From the development of single screw, although the single screw extruder has been relatively perfect in recent years, with the continuous development of polymer materials and plastic products, more characteristic new screws and special single screw extruders will emerge

in all chemical manufacturing industries, plastic extruders can be matched with various plastic forming auxiliary machines such as pipe, film, holding material, monofilament, flat filament, packing belt, extrusion, plate, profile, granulation and cable coating to form various plastic extrusion molding production lines and produce various plastic products

extruders can be divided into single screw, twin screw and multi screw extruders according to the number of screws. At present, single screw extruder is the most widely used, which is suitable for the extrusion of general materials. The twin-screw extruder has the advantages of less heat generated by friction, uniform shear of materials, large conveying capacity of screws, stable extrusion capacity, long residence of materials in the barrel and uniform mixing

sjsz series conical twin-screw extruder has the characteristics of forced extrusion, high quality, wide adaptability, long service life, low shear rate, difficult decomposition of materials, good mixing and plasticization performance, direct tool fastening and moving knife forming of powder, temperature self-control, vacuum exhaust and other devices. It is applicable to the production of pipes, plates, special-shaped materials and other products

single screw extruder plays an important role in achieving comprehensive, harmonious and sustainable development as both plasticizing and granulating machinery and forming and processing machinery. In recent years, single screw extruder has made great development. At present, the large-scale single screw extruder for granulation produced in Germany has a screw diameter of 700mm and an output of 36t/h.

in the plastic extrusion equipment, the air circulation system should be checked. The plastic extruder is usually called the main machine, while its supporting follow-up equipment, the plastic extrusion molding machine, is called the auxiliary machine. After more than 100 years of development, plastic extruders have been derived from the original single screw into twin-screw, multi screw, or even non screw and other models

at present, China's plastic extruder market is developing rapidly, and many new models have been launched. With the joint efforts of technology and R & D personnel in the industry, some main special machines such as exhaust extruder, series grinding disc screw extruder, reciprocating pin screw extruder, foam extruder, extruder with melt gear pump, series multi-stage extruder and planetary screw extruder are produced by domestic manufacturers, It has the ability of independent research and development and enjoys independent intellectual property rights
