At present, China's plastic extruder market is developing rapidly, and many new models are launched. Through the joint efforts of industry technology and R&D personnel, some major special types such as exhaust extruders and tandem disc screws extruders. Reciprocating pin screw extruder, foaming extruder, extruder with melt gear pump, series multi-stage extruder, planetary screw extruder, etc. are produced in China and have independent research and development. Ability and enjoy independent intellectual property rights.
With the upgrading of technology, plastic extruder equipment has long ended the era of manual loading, people can be freed from heavy physical labor and dusty environment. The work originally done by hand is now automatically completed by conveyor equipment. The plastics industry has made a big contribution.
In recent years, a large number of theoretical and experimental studies have been carried out on the screw. Up to now, there have been nearly a hundred kinds of screws, and the common ones are separation type, shear type, barrier type, split type and wave type. From the perspective of single-screw development, although the single-screw extruder has been perfected in recent years, with the continuous development of polymer materials and plastic products, new-type screws and special single-screw extruders with more characteristics will emerge.
In all chemical manufacturing industries, plastic extruders can be used with various plastic moldings such as pipes, films, materials, monofilaments, flat yarns, packing belts, extruded nets, plates, profiles, granulation, cable coating, etc. The machine is matched to form various plastic extrusion molding production lines to produce various plastic products.
The extruder can be divided into single-screw, twin-screw 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.
SJSZ series conical twin-screw extruder has the characteristics of forced extrusion, high quality, wide adaptability, long service life, small shear rate, difficult material decomposition, good mixing and plasticizing performance, direct molding of powder, and temperature control. Vacuum exhaust and other devices. Applicable to the production of tubes, plates, profiles and other products.
Single-screw extruders play an important role both as plasticizing granulation machines and forming processing machines. In recent years, single-screw extruders have developed greatly. At present, the large-scale single-screw extruder for granulation in Germany has a screw diameter of 700mm and a yield of 36t/h.
In plastic extrusion molding equipment, plastic extruders are often referred to as main engines, and the subsequent 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.
At present, China's plastic extruder market is developing rapidly, and many new models are launched. Through the joint efforts of industry technology and R&D personnel, some major special types such as exhaust extruders and tandem disc screws extruders.
