Design and manufacturing of an isostatic press wetbag with two vessels of different volumetric capacities are presented. The isostatic press, widely applied in the forming of ceramic techniques since the beginning of the last century, is still an important laboratory equipment which is required when pressures are up to 500 MPa. The greatest difficulties of the researchers related to these equipments are in operation and maintenance. This paper presents the design of an isostatic press with two different vessels in terms of volumetric capacity, thus depending on the size of the samples in the process, making possible the selection of a suitable vessel or two vessels simultaneously. Hydrostatic pressure of 210 MPa was selected and designed two vessels of internal diameters of 95 mm and 55 mm with clover leaf and threaded lid locks, respectively. A compact, safe, economical and optimized maintenance equipment that accelerates the process and production of test specimens was obtained.
