Isostatic pressing bags

Isostatic pressing method of ceramics

Isostatic pressing is a special molding method developed on the basis of traditional dry pressing! It uses fluid to transmit pressure and evenly apply pressure to the powder in the elastic mold from all directions. Due to the consistency of the internal pressure of the fluid, the powder bears the same pressure in all directions, so it can avoid density differences in the body. Isostatic pressing can be divided into wet bag isostatic pressing and dry bag isostatic pressing. Wet bag isostatic pressing: products with more complex shapes can be formed, but it can only be operated intermittently.

Dry bag isostatic pressing: It can realize automatic continuous operation, but it can only form products with simple shapes such as square, round, tubular cross-sections. Isostatic pressing can produce a uniform and dense body. Ceramic sintering shrinkage is small and shrinks uniformly in all directions. However, the equipment is more complex and expensive, and the production efficiency is not high. It is only suitable for the production of materials with special requirements.

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.
