等靜壓是將預壓好的坯料包封在彈性的橡膠模或塑料模具內，并將其放在高壓容器施加高壓液體，使其形成坯體，這種細說來應該叫做濕式等靜壓，它是等靜壓成型方法的一種類型。這種類型適合多品種、形狀復雜、產量小和大型的產品。
另外，還有一種類型是干式等靜壓，干式等靜壓的模具是半固定式的，添加坯料和取出都在干燥狀態下進行。這種方式適合于形狀簡單的長形、管狀制品。
氧化鋁陶瓷的等靜壓成型法模具制作方便、壽命長、成本低；可以成型以一般方法不能生產的形狀復雜，大件及細長的氧化鋁陶瓷產品，而且質量好；壓力作用效果比其他干壓方法好；可以少用甚至不用粘結劑；不易變形。（圖/文www.xahjbz.com）
中譯英：
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.
