DIP Molds for Isostatic Pressing

DIP Molds for Isostatic Pressing

Isostatic pressing is to add granulated ceramic materials into the mold. The material of the mold is generally plastic or rubber with certain elasticity. The granulated porcelain material in the mold is compacted and shaped. There are two methods of isostatic pressing: cold isostatic pressing and hot isostatic pressing, and cold isostatic pressing is divided into wet and dry.

Cold isostatic pressing

Cold isostatic pressing technology (Cold Isostatic Pressing, referred to as CIP) is at room temperature, usually using rubber or plastic as the jacket mold material, using liquid as the pressure medium, mainly used for powder material molding, for further sintering, forging or heating The isostatic pressing process provides a green body. The general working pressure is 100~630MPa.

Dry bag isostatic pressing

Dry bag isostatic pressing is relative, that is, the mold is not all in the dry isostatic press of high-pressure liquid medium, but semi-fixed, so the addition of blanks and blanks All extractions are performed in a dry state. When the dry mold bag is pressed and clamped by the upper and lower punches, the high-pressure liquid is input to the surrounding of the dry mold bag, so that the powder is shaped by uniform pressure.

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.
