Introduction and Application of Isostatic Pressing Technology

    Isostatic pressing is a new type of production process, mainly used for processing and forming of metal materials. At present, it is widely used in aerospace engineering, vehicles, machinery and other industrial fields. Isostatic pressing is the process of putting the metal material to be formed into the mold, and applying relative negative pressure with isostatic pressing machinery to make the material fully adapt to the shape of the mold. When the material contains a partial proportion of metal or non-metal powder, it can be deformed during the suppression process to form a complete shape and obtain a high-quality finished product. Isostatic pressing has many advantages. It is able to manufacture parts with complex shapes with high precision and does not require more machining and cutting tools. It can also generate materials with different shapes. Because the inhibition process strengthens the material, the method can produce materials with high toughness and high wear resistance. It can also be mass-produced to improve work efficiency and economic benefits. Isostatic pressing technology is usually used to produce metal products such as brake drums, gears, oil pumps, and camshafts.

  Isostatic pressing technology can also be used in the production of wear-resistant ceramic products. Wear-resistant ceramics are produced by isostatic pressing technology, and wear-resistant ceramics with high hardness, high density and low porosity can be obtained. These products have excellent wear resistance, corrosion resistance, high temperature resistance and insulation, so they are widely used in precision instruments, computer manufacturing, aerospace engineering, chemical industry and other fields. In isostatic pressing technology, mold selection is very important. If the mold structure design is unreasonable or low-quality materials are used, the quality of the finished product will be low or even unusable. Therefore, high-quality and suitable molds must be selected and standardized maintenance work must be carried out.

         In isostatic pressing technology, the applied pressure and pressure protection time are also important factors affecting the quality of finished products. The higher the pressure, the denser the finished material, but it also increases manufacturing costs. The longer the pressure protection time, the higher the density of the finished product, but it will reduce the production speed. Therefore, in the suppression process, it is necessary to select the appropriate pressure and pressure protection time for different finished product regulations.

         Generally speaking, isostatic pressing technology is an advanced manufacturing technology with high cost efficiency, high product precision and high reliability. It has become an indispensable production technology in many industries and is widely used in specific production. Therefore, for manufacturers, isostatic pressing technology can improve their production efficiency, reduce their production costs, and obtain higher economic benefits.
