Since 1946, Thompson Investment Casting has been at the forefront of the investment casting industry. Our attention to detail, state of the art facility, and many years of experience combine to produce a smooth surfaced, superior product. We manufacture investment castings for a myriad of industries including medical, sporting, industrial, commercial, and technology. We work most often with steel alloys, copper-base alloys, pure copper and some aluminum. Our capabilities allow us to fabricate complex shapes with fine detail. We can produce castings up to 18 inches in length or width and as thin and .020 of an inch.
