Investment Castings Overview

Welcome to Milwaukee Precision Castings! The premier foundry in the investment castings industry.

Did you know that the origin of the investment casting process also known as lost wax process stretches back to the Chinese dynasties circa 1100 -1700 BC? Throughout the course of many centuries, artists have produced fine jewelry and works of art through the investment casting process. Milwaukee Precision Castings has used the same process to annually produce millions of castings.

During World War II, military demands overtaxed the machine tool industry, so Industrial America started to use the investment casting process. The discovery that a lost art provided a practical meta working technique for wartime needs was met with great enthusiasm.

What is Investment Casting?

Investment casting involves creating an original wax model, coating the image with plaster, and building up successive layers until strong shell envelopes the model.

Milwaukee Precision Casting pours many alloys including:

  • Carbon Steel
  • Stainless Steel
  • Tool Steel
  • Nickel Base
  • Cobalt Base
  • Brass
  • Bronze
  • Copper
  • Aluminum

After melting out the wax, molten gold or bronze would be poured into the mold creating a perfect duplicate of the original wax pattern. Compared to machining a part, investment casting can economically offer undercuts, high definition, complex detail, and a smooth surface finish. Most often investment casting is the only way a part can be economically manufactured.
