Wet-bag Isostatic Pressing Molds

Wet-bag Isostatic Pressing Molds

Usually referred to as isostatic pressing refers to cold isostatic pressing, which is a method of using fluid (water, oil) as a transfer medium to obtain uniform static pressure applied to the material. That is, the incompressibility of the liquid medium is used to transfer the pressure uniformly, and the pressure is applied from all directions to obtain the molding method of the product. According to its forming process, it can be divided into two forms: wet bag type and dry bag type. At present, the wet bag method is mainly used in large quantities.

Wet bag isostatic pressure

Wet bag isostatic pressing technology is to place granulated ceramic powder or pre-formed billet into a deformable rubber envelope, and then apply uniform pressure in all directions through the liquid. When the pressing process is over, the rubber envelope containing the billet is removed from the container, which is a discontinuous forming method.

The cost of this technology is relatively low, it can form moderately complex parts, and the pressure can reach 500MPa, which is suitable for small-scale production, but the number of molded products is small in a certain period of time, the size and shape of the compact are not accurately controlled, the production efficiency is not high, and the large-scale production cannot be continuous.

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.
