The wear resistance of the screw barrel of injection molding machine is mainly achieved by special materials and structural design. injection molding machine screw barrel is usually made of high hardness, high wear resistant materials, such as tungsten carbide alloy, chromium alloy, etc. After special treatment, the hardness of these materials can reach more than 1000HV, thus significantly improving the wear resistance .
Specifically, the material and structural characteristics of the injection molding machine screw barrel are as follows:
material : commonly used materials include tungsten carbide alloy, chromium alloy, nickel alloy and so on. These materials have good hardness and wear resistance, and can effectively resist wear and corrosion .
structure design : bimetal parts design is a common structure, the screw adopts slotted alloy spraying, the barrel adopts centrifugal casting, the effective part of the head ring pad is alloyed, this design significantly improves the wear resistance and service life .
