【Know Tungsten】Tungsten Copper CIP

tungsten copper CIP picture

Cold Isostatic Pressing, CIP, it refers to the isostatic pressing technique carried out at the room temperature. CIP usually uses rubber and plastics as mold wrapped materials, the liquid as the medium, the pressure is 100-630MPa, which mainly applied in powder molding. The purpose is to provide a sintered preform for the next process, such as forging or HIP process and so on. Compared with common molding process, tungsten copper CIP process has more uniform compacts and higher efficiency.
