Plastic Extruder In The Plastics Processing Industry Has Been Widely Used

Plastic Extruder in the plastics processing industry has been widely used
Nearly 20 years ago, we knew that the extruder was usually made by hand, and it was hard to add the pellets from a place into a bag or box to the hopper of the extruder. However, with the introduction of automation technology in the plastic processing process, people can be freed from heavy physical labor and dusty environments. The work done by the manual is now done automatically by the conveyor equipment.

      The extruder can be divided into single screw, twin screw and multi screw extruder according to its screw number. At present, the most widely used single screw extruder is suitable for the extrusion of general materials. Twin screw extruder due to the friction generated by less heat, the material is more uniform shear, the screw conveying capacity is larger, the extrusion is relatively stable, the material in the barrel to stay long, mixed evenly. SJSZ series of conical twin-screw extruder with forced extrusion, high quality, wide adaptability, long life, low shear rate, easy decomposition of materials, mixing plasticizing performance, powder molding and other characteristics, temperature control, Vacuum exhaust and other devices. Applicable to the production of tubes, plates and profiled products.

Single screw extruder both as a plasticizing granulation machinery or forming processing machinery have an important position in recent years, single screw extruder has been a great development. At present, the German production of large-scale granulation with a single screw extruder, screw diameter of 700mm, the output of 36t / h. The main sign of the development of single screw extruders lies in the development of its key parts - screw.

      In recent years, people have carried out a lot of theoretical and experimental research on the screw, has been nearly 100 kinds of screw, common separation, shear type, barrier type, shunt type and wave type. From the development of single screw, although in recent years, single screw extruder has been more perfect, but with the continuous development of polymer materials and plastic products, but also the emergence of more features of the new screw and special single screw extruder.

      In the Plastic Extruder, Plastic Extruder is usually called the host, and its supporting follow-up equipment, plastic extrusion machine is called auxiliary. Plastic Extruder after 100 years of development, has been derived from the original single screw twin screw, multi-screw, and even no screw and other models. Plastic Extruder can be with the pipe, film, holding materials, monofilament, flat wire, packing belt, squeeze network, sheet, profile, granulation, cable coating and other plastic molding auxiliary equipment to match the composition of a variety of plastic extrusion A molding production line, the production of various plastic products. Therefore, the plastic extrusion molding machinery, whether present or future, are the plastics processing industry is widely used in one of the models.
