Twin City Metal Seal

Your Powder Coating and Vacuum Impregnation Specialists.

Twin City Metalseal, Inc. is a vacuum impregnation company as well as a powder coating company that serves the Minneapolis and St. Paul, Minnesota metro area.

Impregnation can be performed on castings before or after machining, as in the case of powdered metal parts and some sand castings. Die castings should be impregnated after all machining has been done to ensure that all porosity has been uncovered. It has been proven to be more cost effective to impregnate rather than to scrap castings. If a casting has had expensive machining processes there is no way to recover that cost if the casting is scrapped. It has been calculated by engineers that impregnation is a small cost when recovering expensive components. We proudly meet Military Standards for vacuum impregnation.
