Polyurethane Isostatic Pressing Mold

Polyurethane Isostatic Pressing Mold

Powder forming, one of the most important pressing methods is isostatic pressing forming, uniform texture after pressing, can achieve very high quality. Elastomer moulds are needed in the isostatic pressing process, among which polyurethane isostatic moulds are widely welcomed, because they have the advantages of high rebound, easy degumming, oil and water resistance, tear resistance, long service life, smooth surface of products and so on.

In isostatic pressing, the pressure transmitted by the liquid medium is equal in all directions. When the elastic mold is subjected to the pressure of the liquid medium, the deformation is transferred to the powder in the mold. The friction between the powder and the mold wall is small, the force of the blank body is uniform, the density distribution is uniform, and the product performance is greatly improved. Isostatic pressing in a broad sense is also divided into cold isostatic pressing and hot isostatic pressing. Cold isostatic pressing is the isostatic pressing method of forming the workpiece at room temperature. Hot isostatic pressing is a special sintering method in which the workpiece is formed and sintered at high temperature and high pressure. Hot isostatic pressing is mainly used in the molding of high performance powder material products, such as powder metallurgy superalloy, powder metallurgy high speed steel, ceramic materials and other industrial production.

Isostatic die for use has polyurethane isostatic die and rubber isostatic die. In traditional isostatic pressure equipment, rubber is widely used because it is used in isostatic pressure die earlier. But in recent years, polyurethane has gradually become known to people. Because of its excellent elasticity, it is replacing rubber products in various industries at an amazing rate, including isostatic rubber molds in isostatic pressure equipment.

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.
