This facility includes primary zinc and aluminum die casting departments which produce casts from one gram to five pounds; a secondary operations department with drills, presses, and special machinery; a Tool Room to comply with in-house requirements for gauges, fixtures, die and mold building and repair, and shop machine maintenance; a Quality Control department with the necessary equipment and gauges.

SDC was originally founded in the early 60's by Barclay F. Smith as Scotch Diecasting Company. The company operated in Berkley, MO, a suburb of St. Louis.

In 1976 the company was sold and later re-incorporated as SDC Inc.  B.F. Smith later went on to found other companies in the St Louis area before fully retiring.

In 1980 SDC constructed a 15,000 sq. ft. manufacturing plant situated on a 3 acre lot in Sullivan, MO. Zinc die casting was its main focus, but aluminum die casting was soon added to facilitate new customers. Throughout the 80's and 90's secondary services continued to be added to add value the castings being produced.

In 2016 SDC constructed an additional 8,500 sq. ft. onto existing building for increased manufacturing space and improved shipping / warehouse space.

Like many companies in the past several years, SDC has redefined its core business of 30 years and became a leaner and more agile supplier. We have expanded services and responsibilities to a broader range of products and materials.
