A key component of producing exceptional precision cast parts is investment casting tooling. While other casting processes have their own benefits for some applications, investment casting is often the optimal choice when taking all factors into consideration. Tooling is the first step in achieving such excellent results. The process begins with the design and production of a split aluminum tool, also called a die. The quality and accuracy of this tool is essential because it defines the geometry and characteristics of every casting produced. The tool creates wax patterns that are layered with ceramic and stucco material, which produce molds for the castings. The castings are only as good as the tooling. That is one of the reasons why it is cost effective in the long term to invest somewhat more upfront for the tooling than in some other processes. Manufacturers typically find that the overall ROI is worth the cost.
