Single Screw And Barrel Of Injection Molding Machine

The main character of NHY screw is high precision,high stability and high durability,we use hard alloy spraying the whole circle around the easy-damage part of the barrel inside, hardness reach to 62HRC. The depth of the alloy layer is 2.5-3mm, adding Tungsten alloy besides the normal alloy, thus it can largely improve the wear resistance and use life.
