DESCRIPTION


The principle of isostatic pressing

According to Pascal's law, the pressure on the surface of the fluid in the pressurized airtight container can equally transmit the surface pressure in all directions according to the original size and is proportional to the area of the surface. This is the theoretical basis of isostatic pressing technology.

Isostatic pressing technology is to place the powder of the sample to be pressed in a high-pressure container, and use the incompressible nature of the liquid medium and the property of uniformly transmitting pressure to uniformly pressurize the sample from all directions. When the liquid medium is injected through a pressure pump. When a pressure vessel is used, according to the principle of fluid mechanics, its pressure is constant and uniformly transmitted to all directions. At this time, the pressure of the powder in the high-pressure container in all directions is uniform and consistent in size. The method of forming the barren powder into a dense body by the above method is called isostatic pressing.

Cold isostatic pressing (application of CP technology)

Cold isostatic pressing technology has a long history of development. In 1913, the American Westinghouse Electric Company HDMadden first invented it to process high melting point metal powder ingots. It was not until the early 1950s that the laboratory gradually began to apply it. With the development of high pressure technology, cold isostatic pressing technology has been industrially applied since the mid-1950s.

Because cold isostatic pressing technology can improve product performance, improve product quality, and increase economic benefits, it has many attractive advantages compared with other molding processes. Therefore, the application field is expanding and the technology is becoming more and more mature. So far, there are hundreds of varieties of products using isostatic pressing technology. In recent decades, it has been widely used in powder metallurgy, graphite, ceramics, plastics, refractory materials, cemented carbide and other industrial sectors.

Cold isostatic pressing technology is not only used for the molding of various powder products under the state of ultra-high pressure in all directions, but also in the fields of biopharmaceuticals such as high-pressure sterilization of food, extraction of drugs and protein activation.
