等静压是将预压好的坯料包封在弹性的橡胶模或塑料模具内，并将其放在高压容器施加高压液体，使其形成坯体，这种细说来应该叫做湿式等静压，它是等静压成型方法的一种类型。这种类型适合多品种、形状复杂、产量小和大型的产品。
另外，还有一种类型是干式等静压，干式等静压的模具是半固定式的，添加坯料和取出都在干燥状态下进行。这种方式适合于形状简单的长形、管状制品。
氧化铝陶瓷的等静压成型法模具制作方便、寿命长、成本低；可以成型以一般方法不能生产的形状复杂，大件及细长的氧化铝陶瓷产品，而且质量好；压力作用效果比其他干压方法好；可以少用甚至不用粘结剂；不易变形。（图/文www.yxwdcy.com）
中译英：
Static pressure is the pressure of blank entrapment in the elastic rubber die or plastic within the mold, and put it in a high-pressure container exerts high-pressure liquid, to form a billet body, this exactly should be called wet isostatic pressing, it is the isostatic pressing method of a type of. This type is suitable for many varieties, complex shape, production of small and large products.

Alumina ceramic isostatic press molding method die convenient manufacture, long life, low cost; can be molded to a general method can not produce large and complex shape, thin alumina ceramic products, but also of good quality; pressure effects other than dry pressing method can use less or even no good; binder; not easy to deformation.
