Rubber barrel screw

The bimetallic rubber barrel is made by high-temperature and high-speed centrifugal casting, with an alloy layer thickness of 2mm-3mm on one side. The inner wall of the barrel has the characteristics of high hardness, high wear resistance, and corrosion resistance. The surface of the screw edge is coated with tungsten carbide alloy at high temperature, with a thickness of 1.5mm~3.5mm and an alloy code of HRC58~62. It is suitable for the production of rubber products such as pin cold feeding, ordinary cold feeding, exhaust cold feeding, new hot feeding, rubber extrusion, rubber injection, rubber magnetic strips, etc.
