Unlike standard industrial products, most investment castings are manufactured according to customer drawings. This means each new component usually requires its own dedicated tooling.
Several factors determine how the tooling is designed, including:
Part geometry
Overall dimensions
Wall thickness
Draft angles
Production quantity
Material shrinkage
Even small design changes may require modifications to the tooling or, in some cases, an entirely new tool. For this reason, finalizing the product design before tooling production begins is one of the most effective ways to control investment casting tooling costs.
