Advanced Seal Technology specializes in casting and powdered metal impregnation. Impregnation is the process in which porosity is eliminated in cast and powdered metal. It is the most effective method, preventing leaks of fluid or gases, preventing plating defects, and increasing machinability.

Castings that are processed properly have no change in appearance or size. The seal in our impregnated castings is permanent. Our sealants can resist pressure that is equal to the bursting point of the part.
