Information
Both the extruder screw and the injection molding machine screw are plastic processing machines. The two sound similar, but they are actually different. There are many differences between the plastic extruder screw and the injection molding machine screw. The following are introduced by the professionals of the plastic extruder screw to learn more about the two machines.
 
The extruder extrudes the molten plastic through a fixed-shaped extrusion port under the effect of the screw, and cuts it by water-cooling after the effect of the tractor. It is mainly used for the continuous production of various products of the same cross section, such as tubes, rods, profiles, etc., and can also be used for plastic modified granulation. Its plastic processing is called extrusion molding.
 
The injection molding machine injects molten plastic into the mold and cools it into a product. It is widely used, depending on the plastic, the local use is different. This process is called an injection molding process.
 
Under the image of our image, the injection molding machine melts the plastic particles and then injects them into the closed cavity. After filling the cavity, the machine is suspended. After cooling, the plastic is shaped into a shape, and the mold is opened again. . Such as plastic cups, plastic pots and other plastic products. The extruder is continuously extruded through a mold after melting the plastic particles, such as a plastic tube or a plastic plate, and the subsequent process is further cut. The two machines not only process different materials, but the structure of the screw is also different.
 
The processing data is also different, and the viscosity of the data is different. Injection molding requires plastic materials to flow in the mold, and the flow path is generally curved and narrow, thus requiring the fluidity of the plastic raw materials to be absolutely good.
