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.
