Investing in metal tooling when casting can be an expensive process

In addition to the wax patte, the investment casting process uses lost wax injection tooling to create dimensionally accurate solid wax pattes. These pattes are the foundation of the ceramic mold. This tooling must be designed to be easy to use, durable, and efficient.
Investing in metal tooling

Investing in metal tooling when casting can be an expensive process. Purchasing new molds and dies for casting can cost thousands of dollars. Additionally, these metal tools must be made to the exact specifications of the part being cast. These metal tools are called investment casting tools. The investment  Alloy steel casting  in new tooling is often offset by the amount of time and money saved by eliminating secondary machining. However, if the casting run is small, it will be difficult to recover the cost of the new molds.

Investment casting tools are critical to the production process. Typically, the tooling consists of a master patte, a mould, and wax pattes. These tools are extremely important because they must be designed for ease of use, maximum efficiency, and durability.
Investing in refractory materials

Investment casting is an industrial process that uses a mold and refractory material to create complex shapes. The process is based on one of the oldest metal-forming techniques. The patte is then coated with a refractory material, such as brass, carbon steel, aluminum, or glass. The resulting multilayer shell is then cooled and de-molded. Sometimes a sand-filled mold is used to produce the refractory material, while in others, the casting process is direct and requires no sand.
