What is the initial step in the investment casting process?

The investment casting process begins with creating a wax pattern, which is a replica of the final product. This pattern is crucial because it determines the shape and dimensions of the casting. Moulding the wax pattern involves creating this detailed form, which is then used in subsequent steps of the process.

After the wax pattern is made, it will be coated in a ceramic material to create the mould, followed by a heating step to remove the wax and harden the ceramic, but these steps come later in the process. Therefore, starting with the creation of the wax pattern is foundational to ensure that the subsequent phases can proceed effectively. The accuracy and quality of the initial wax pattern directly influence the effectiveness of the entire investment casting process.
