About Isostatic Pressing

The isostatic pressing method is a method in which equal pressure is applied to the mud in all directions for molding. The commonly used stress transmission medium is liquid, such as oil, water or glycerin. Because the compressibility of brake fluid or anhydrous glycerin is very small, almost all the pressure can be transmitted to the elastic mold, so these two liquids are often used as pressure transmission medium.

The characteristic of isostatic pressing is that each part of the powder is pressed evenly and at a high pressure, so that the green body obtained in this way has a high and uniform density, so that the deformation and shrinkage of the green body during the firing process are greatly reduced, and it will not The green body formed by the general molding method has firing cracks caused by the stress caused by the density difference. In addition, the pressurization operation of isostatic molding is simple, and the molding pressure is easy to adjust; the isostatic pressing mold is easy to manufacture, accurate in molding, and can be used repeatedly ; The temporary binder may not be used or less used in the mud. Isostatic pressing can be used to press large and slender products with complex shapes that are difficult to form by general molding methods, such as long nozzles, submerged nozzles, tuyere bricks, and integral stoppers.

The biggest feature of isostatic pressing is that each part of the mud is pressed evenly and at a high pressure, so that the green body obtained in this way has a high and uniform density, so that the deformation and shrinkage of the green body during the firing process are greatly reduced, and the pressure is not high. There will be firing cracks caused by the stress generated by the green body formed by the general forming method due to the density difference. In addition, the pressurization operation of isostatic pressing is simple, and the molding pressure is convenient to adjust; the rubber or plastic molds for molding are easy to manufacture, low in cost, and can be used repeatedly; no or less temporary binders can be used in the mud. Isostatic pressing can be used to press large and slender products with complex shapes that are difficult to form by general molding methods, such as long nozzles, submerged nozzles, tuyere bricks, and integral stoppers.
