big size custom-made CIP bags, cold isostatic pressing bags manufacturer-Jiangsu high industry tech Co., Ltd. Isostatic pressing is to place the object to be processed in a closed container filled with liquid, and gradually pressurize it through a pressurization system to apply equal pressure to each surface of the object, so that the molecules can be reduced without changing the appearance and shape. The distance between them increases the density and improves the physical properties of the material. Isostatic pressing is to add granulated ceramic material into the mold. The mold material is generally plastic or rubber with certain elasticity. In the isostatic pressing machine, a uniform pressure of tens to hundreds of MPa is applied to the mold in all directions. The granulated ceramic material in the mold is compacted and formed. There are two methods of isostatic pressing: cold isostatic pressing and hot isostatic pressing. Cold isostatic pressing is divided into wet and dry.
The working principle of isostatic pressing technology is to put the pressed blank into a closed high-pressure cavity, cover the outer surface of the blank with an elastic mold envelope, fill the high-pressure cavity with high-pressure liquid, and apply a high pressure of hundreds of megapascals. The body is subjected to uniform pressure in all directions and shrinks uniformly. After reaching a predetermined pressure and maintaining it for a certain period of time, a highly densified green body can be obtained. The green body after isostatic pressing has good strength and is convenient for machining. The green body has good compactness and uniformity, and improves the mechanical properties.
