Functions of Rubber Screw Of The Extruder and its application in plastic extrusion production

In the plastic extrusion production process, the Rubber Screw Of The Extruder plays a vital role. It is not only the core component of the extruder, but also the key to achieving uniform and continuous extrusion of plastic materials. This article will take an in-depth look at the functions of a rubber extruder screw and its application in plastic extrusion production.
First of all, the main function of the rubber extruder screw is to transport, plasticize and compact plastic materials. The screw rotates to suck the plastic material from the hopper and push it forward along the spiral channel of the screw. During this process, the material is sheared, rubbed and mixed by the screw and the inner wall of the barrel, and gradually plasticizes, that is, it changes from a solid or semi-solid state to a viscous flow state. At the same time, the rotation and propulsion of the screw cause the material to be compacted during the extrusion process to ensure the density and uniformity of the extrudate.
In plastic extrusion production, rubber extruder screws are widely used. It can be adapted to the extrusion processing of a variety of plastic materials, such as polyethylene, polypropylene, polyvinyl chloride, etc. By adjusting the structural parameters and operating conditions of the screw, such as rotation speed, temperature, etc., precise control of the shape, size and performance of the extrudate can be achieved. In addition, the rubber extruder screw is often used in conjunction with other auxiliary equipment, such as molds, cooling devices, etc., to further improve the quality and production efficiency of the extrudate.
However, the design and use of rubber extruder screws also have certain technical difficulties. Its structure is complex and needs to take into account the requirements of material transportation, plasticization, compaction and other aspects. At the same time, factors such as screw material selection, processing accuracy and wear resistance also directly affect the service life and performance stability of the extruder. Therefore, when selecting and using a rubber extruder screw, factors such as process requirements, material characteristics, and equipment conditions need to be fully considered.
In short, Rubber Screw Of The Extruder plays an irreplaceable role in plastic extrusion production. It can not only achieve uniform and continuous extrusion of plastic materials, but also improve the quality and production efficiency of extrudates through precise control of the extrusion process. With the continuous development of plastic processing technology, it is believed that rubber extruder screws will play a more important role in the future.
