Materials need to be treated according to the situation. The most typical methods include “capsule method” and “non capsule method”.

As shown in the figure on the right, “capsule method” is to put the powder or the object formed by the powder into the airtight capsule and empty the capsule before hip replacement.

This “capsule method” can provide high density even for materials that are difficult to be sintered by ordinary sintering technology. Therefore, it is most commonly used in the pressure sintering process of powder materials. It can also be used for diffusion bonding or high pressure impregnation carbonization of various materials.

This material does not require capsule hip treatment, which is known as the “no capsule method.”. It is used to remove the residual pores on the sintered parts, eliminate the internal defects of the castings, and repair the parts damaged due to fatigue or creep.
