Porosity voids are always present in powdered or sintered metal parts. This inherent structural porosity weakens the parts’ performance in pressure applications, resulting in leaks and plating problems.

The solution is to seal porosity through vacuum pressure impregnation. To permanently seal the porous powdered metal and sintered parts for pressure tightness, Imprex removes air from the porosity, fills the pores with sealant, removes excess sealant from the exterior of the part, and cures the part. This process ensures that any and all leak paths are sealed and eliminated.
