Since the pattern is destroyed in the process, one will be needed for each casting to be made. The pattern for this process may also be made from plastic however it is often made of wax since it will melt outĮasily and wax can be reused. The first step in investment casting is to manufacture the wax pattern for the Manufactured in industry by this process include dental fixtures, gears, cams, ratchets, jewelry, turbine blades, machineryĬomponents and other parts of complex geometry. InvestmentĬasting was developed over 5500 years ago and can trace its roots back to both ancient Egypt and China. This manufacturing technique is also known as the lost wax process. The metal solidifies within the ceramic moldĪnd then the metal casting is broken out. Melted out and molten metal is poured into the cavity where the wax pattern was. Once the ceramic material is hardened its internal geometry takes the shape of the casting. Investment casting is a manufacturing process in which a wax pattern is coated with a refractoryĬeramic material.
