Technical Innovation Of Plastic Single Screw Extruder

      Screw extruder is one of the most important equipment in plastic forming process, which is formed by solid conveying, compaction, melting and shearing of plastic through external power transfer and heat transfer of external heating elements. Screw Extruder Since its inception, after nearly a century of development, has been developed by ordinary screw extruder as a new type of screw extruder. Although the new type of screw extruder has a wide range of types, the extrusion mechanism is basically the same.Plastic Single Screw Extruder
     The extrusion process of the traditional screw extruder is realized by the heat of the barrel, the solid material and the barrel, the screw friction and the melt shearing force. "Friction coefficient" and "friction", "viscosity" and "shear stress" are the main factors affecting the performance of traditional screw extruder, because the factors that affect "friction" and "viscosity" are very complicated, the extrusion process of traditional screw extruder is a unsteady state, which is difficult to control, and has poor thermal stability, Heat-sensitive plastics with high viscosity are especially prominent.Plastic Single Screw Extruder
     Since the 60 's, scholars in the world have done a lot of research on the mechanism of screw extrusion, and made obvious achievements, but because their research is mostly confined to the traditional plastic extrusion mechanism, mechanical structure form and energy-Exchange Mode, so it has not achieved a major breakthrough.
     Traditional screw extruder such as large volume, high energy consumption, noise, product quality and so on a series of shortcomings have not been fundamentally resolved. After two years of hard work, 1990 finally developed the first plastic electromagnetic dynamic plastic extruder principle prototype, the principle prototype adopts the Direct Energy Exchange method, introduces the vibrating field into the plastic extruding process, from the principle to the mechanical structure is completely different from the traditional screw extruder, overcomes many defects of the traditional equipment, has the small size, Light weight, low manufacturing cost, low energy consumption, small noise, good plastic mixing effect and other advantages.Plastic Single Screw Extruder
    Twin-screw market innovation technology trends: twin-screw processing technology has become a very common application of plastic processing, the corresponding competition is extremely fierce. How to be invincible in the fierce competition? Different suppliers have introduced unique innovative technologies to win the market. High-speed, high production speed, efficiency, energy-saving has been the main theme of the continuous improvement of international plastics machinery in recent years.Plastic Single Screw Extruder
