Tooling Design for Investment Casting

When it comes to metal casting and CNC machining, tooling refers to reusable items that are utilised for each job. Wax-injection dies are used as tooling to create wax patterns in investment casting. 

If you know how investment casting works, you already know that the investment casting process relies on these wax patterns. Wax has smooth surfaces, low melting temperatures, and excellent flow properties enabling highly complex investment castings to be made.

By following strict guidelines based on decades of experience, foundries can recommend design changes to improve product quality and function, as well as to increase production efficiency and decrease manufacturing costs.

Most of the time, the customer is in charge of the casting design. Casting facilities work with customers to optimise designs for manufacturability and to ensure they pass through a rigorous Advanced Planning Quality Process (APQP).
