Cold Isostatic Pressing Molds

Cold Isostatic Pressing Molds 

Cold isostatic pressing: Usually, the powder is sealed in a soft sheath, and then placed in a liquid medium in a high-pressure container, and the powder is uniformly pressed in all directions by applying pressure to the liquid, so as to obtain the required compact. The liquid medium can be oil, water or glycerin. The sheath material is an elastic-plastic material such as rubber. Metal powder can be directly loaded or molded to fit the sleeve. Because the powder is uniformly pressed in all directions in the sheath, a compact with a relatively uniform density can be obtained, so it is not easy to deform and crack during sintering. The disadvantage is that the dimensional accuracy of the compact is poor, and machining is required. Cold isostatic pressing has been widely used in the forming of cemented carbide, refractory metals and various other powder materials.

Compare to traditional rubber cold isostatic pressing bags, the polyurethane CIP bags have significant advantages. As a new polymer material, polyurethane products feature smooth surface, wearing-resistant, anti-fatigue, low deformation rate. The surface of pressed products with polyurethane bags is much smoother than that pressed with rubber bags, thus it possesses better looks and less postprocessing is required. It’s an ideal tool for powder material forming by press process, which can help a company reduce cost and increase efficiency.

Durability and deformation rate are factors that users care most. A long working life of pressing bag can reduce cost and increase production efficiency, while low deformation rate of the bag will enhance precision and yield of products. By close cooperation with material suppliers and great mass of manufacturers of carbide, ceramics and graphite products, we accumulated a lot of experience in this industry and become a well-know supplier of CIP bags.
