W M Heitgras Co.

In 1950, Jake's Foundry, now Metal Dynamics Corporation, was founded primarily to produce sand castings for oil field equipment manufactures. The principal alloy cast was aluminum bronze although other copper alloys as well as aluminum were also produced. In 1977, the company changed its name to Metal Dynamics Corporation, and in 1980, the company expanded into a new facility in the near northeast section of Tulsa, Okla. MDC may not be considered an old company by some standards, however since 1950, it has been producing high quality castings for a variety of applications. The techniques we used in 1950 would hardly be recognized in the plant today.
