Polyurethane Isostatic Pressing Molds for Isostatic Graphite
Polyurethane Isostatic Pressing Molds for Isostatic Graphite
Different from ordinary extrusion and molding, isostatic graphite is formed using cold isostatic pressing technology. The raw material pressed powder is filled into the rubber mold, and the pressed powder is compacted through high-frequency electromagnetic vibration. After sealing, vacuuming is performed to discharge the air between the powder particles and placed in a high-pressure container filled with liquid media such as water or oil. Pressurize to 100-200 MPa and press into cylindrical or rectangular products.
According to Pascal's principle, pressure is added to the elastic mold through a liquid medium such as water, and the pressure in all directions is equal. In this way, the pressed powder particles are not oriented in the filling direction in the mold, but are compressed in an irregular arrangement. Therefore, although graphite is anisotropic in crystallographic properties, overall, isostatically pressed graphite But it is isotropic. In addition to cylinders and rectangles, the formed products also have shapes such as cylinders and crucibles.
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.
