Isostatic Pressing Bags for Ceramic Balls

Isostatic Pressing Bags for Ceramic Balls

Ceramic ball powder isostatic molding mold, ball valve isostatic molding mold, spherical circular isostatic mold rubber sleeve, isostatic molding method is currently the most advanced molding process method, the investment is relatively large compared to other molding, but the The shape and density of the finished grinding balls are a major improvement on the forming quality of the above grinding balls. At present, many grinding balls have been put into use.

For large-size zirconia ceramic balls, the cold isostatic pressing molding process is often used, that is, the powder slurry is sprayed and granulated, and then put into a specially designed hard rubber mold bag for cold isostatic treatment to obtain a ball blank. The green body obtained by this process has high density and is sintered into porcelain with good material and high density. However, due to the limitation of the mold, the roundness of the billet is not good, and the edges formed on the surface need to be further polished. At the same time, the investment cost of the process equipment is large, and the production cost is high.
