​Cold Isostatic Pressing

Cold Isostatic Pressing

Isostatic pressing technology is a powder molding process that uses products in a closed high-pressure container. It applies the same pressure to the powder blank in all directions, so that the powder product has the most uniform density distribution and grain structure. This process is mainly used for forming parts with simple or complex shapes that require uniform strength and fracture resistance, and can also manufacture powder metallurgy products with a large aspect ratio. Let me introduce to you the working principle and scope of application of the cold isostatic press.

Cold isostatic pressing is a kind of powder molding equipment under ultra-high pressure state. Usually, rubber or plastic is used as the mold covering material, and liquid is used as the pressure transmission medium to apply the same pressure to the powder blank in all directions to press it into a predetermined shape. Provide blanks for the next step of sintering, forging or hot isostatic pressing.

     Cold isostatic pressing is widely used in cemented carbide, powder metallurgy, high-speed steel, titanium and titanium alloys, refractory materials, graphite, and crucibles because it can obtain high-density, excellent material homogeneity products for powder raw materials , ceramics, rare earth permanent magnets, crystals, medicine and food industries in a wide range of fields. Cold isostatic pressed products are very conducive to mechanical processing, and can also produce products with various shapes and complex shapes.

Jiangsu High Tech Co., Ltd. is located in Zhenjiang, Jiangsu. It is a high-tech enterprise that develops and produces high-performance polyurethane products, cold isostatic pressing molds and cold isostatic pressing machines. The company's main products are polyurethane isostatic pressing molds and cold isostatic pressing machines. The company's products are widely used in all walks of life in China and exported to more than 30 regions around the world. They are widely praised by customers for their excellent quality and good service. The company always adheres to the product concept of "quality first" and has a deep understanding of customer needs. The company has been committed to the research and development and production of high-performance polyurethane elastomer molds for many years, and solves various design and production problems of polyurethane elastic molds for isostatic pressing users. The company has mature production and processing technology and a complete set of experimental equipment for mold elastomer analysis. In order to ensure the excellent impact resistance, abrasion resistance, cutting, tear resistance and clarity of the product and excellent dimensional stability. Its products are widely used in magnetic materials, ceramics, cemented carbide, high temperature refractory materials, rare earth permanent magnets, carbon materials, rare metal powders and other industries.

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.
