Did You Know?

  • Investment casting is based on, and often called, lost-wax casting.
  • Benefits of investment casting include the ability to produce parts with accuracy and repeatability.
  • Investment casting is one of the oldest known techniques for metal forming.

A Brief History of Investment Casting

First used for crafting jewelry and statues using beeswax, clay and primitive furnaces, investment casting dates back thousands of years. Investment cast artifacts have been found throughout the world from the Aztecs to the Egyptians.

The modern investment casting process and use of more sophisticated materials was developed by dentists in the late 19th century. World War II was the catalyst for further process improvement and capabilities due to the increase in demand for precision-shaped manufactured parts. Specialized alloys and more complex geometries previously only made possible by machining are now made by the investment casting process. The investment casting process is an affordable solution for commercial and aerospace applications.
