ISOSTATIC PRESSING MOLDS/BAGS

ISOSTATIC PRESSING MOLDS/BAGS

The typical process is to put the powder into an elastic soft cover, seal the soft cover and put it into a sealable container (cylinder), the pressure of the liquid medium acts on the cover evenly, and then transmits the pressure to the workpiece. Realize isostatic pressing. The commonly used liquid medium is a mixed emulsion of water and oil or oil, so it is called "hydrostatic pressure" and "oil static pressure". Cold isostatic pressing is mostly used in powder metallurgy to obtain powder preforms. In the mid-1930s, cold isostatic pressing began to be used to press tungsten, molybdenum and ceramic products. Compared with mechanical pressing, due to the high pressure of cold isostatic pressing and the uniform force on the workpiece, it is especially suitable for pressing large-sized powder products. The pressed powder product has the advantages of high density and uniform density, and the pressed powder does not need to add lubricants. The working pressure of the commonly used cold isostatic press can be as high as 6500kgf/cm2.

Cold isostatic pressing is divided into dry bag molding and wet bag molding according to different powder loading methods. We also developed wet isostatic pressing molds, dry bag isostatic pressing molds, and dry bag isostatic pressing machine sealing rubber sleeves. The fundamental difference between the two is: the isostatic pressing mold of the dry bag mold is not soaked in the liquid medium, after the pressing is completed, the briquette and the mold bag are taken out, and the pressurized bag remains in the container for the next filling; The mold bag pressed by the bag mold has a long service life and high production efficiency, and is suitable for single-piece continuous production. Wet bag molding is a commonly used pressing process. After loading, the mold bag is placed in a container and soaked in a liquid medium. After pressing, the mold bag and blank are taken out at the same time.

 Jiangsu High Industry focuses on the research and production of isostatic pressing moulds, customizes various dry bag and cold isostatic pressing moulds, adapts to different models of various manufacturers at home and abroad, and deeply understands the needs of various industries. Alloy, graphite and other industries provide high-performance isostatic pressing mold rubber sleeves.

Product overview: Isostatic pressing rubber mold is used for the molding of ceramic materials, tungsten and molybdenum materials, graphite materials, refractory materials, and alloy powders. It can be customized according to drawings, and can be designed according to samples.

Product features: The deformation of the elastic mold under the pressure of the liquid medium is transmitted to the powder in the mold. The friction between the powder and the mold wall is small, the blank is uniformly stressed, and the density distribution is uniform, and the pre-pressed blank is encapsulated. In the elastic rubber mold, it is put into the high-pressure cylinder after sealing, and the green body is compressed and formed by liquid transfer.

Product advantages: The design of the mold cover is reasonable to ensure no water leakage, the blank is well formed, and the service life is long, including the fixture for processing the blank, which can be customized! There is a free amount of open steel molds.

We support all kinds of customization, if you need it, please contact us.
