The circumferential pressurization system applies pressure only from the outer surfaces of the forming rubber mold through a cylindrical pressing rubber mold as shown in the right figure below.Metal mold pressing is very similar to CIP.With quality and productivity in focus.However, due to the fluid-like property of the powder, the pressure applied to the green compact is almost equal to isostatic pressure.Rolling, machining or sintering.The circumferential axial pressurization system applies pressure from the outer surfaces of the mold and the top surface of the cap-shaped pressing rubber mold as shown in the left figure below.Hot isostatic pressing hIP ) is a manufacturing process, used to reduce the porosity of metals and increase the density of many ceramic materials.Hardcover isbn, edition Number 1, number of Pages.Additive Manufacturing 3D printing of metals combined with HIP processing offers the possibility to produce parts with qualities that are comparable to those resulting from conventional manufacturing methods.The pressurizing gas most widely used is argon.An inert gas is used, so that the material does not chemically react.
There are two structural types: the external pressurization type shown in the left figure below, which pressurize the pressure medium into the pressure vessel from outside, and the piston direct pressurization type shown in the right figure below, which directly pressurizes the pressure medium sealed.
The chamber is heated, causing the pressure inside the vessel to increase.
