Investment casting (also called "lost wax" or "precision" casting) is a manufacturing process in which a wax pattern is created,
gated onto a sprue and repeatedly dipped into a liquid ceramic slurry. Once the ceramic material hardens, its internal geometry
takes the shape of the casting. The wax is melted out, and molten metal is poured into the cavity where the wax pattern was. The
metal solidifies within the ceramic mold, and then the metal casting is broken out.
Excellent precision, ideal for complex geometries
Can meet tight tolerance requirements
Superior surface finish, little additional machining required
Higher total cost than other casting processes
Lower tooling costs
Suitable for both ferrous and non-ferrous metals
Some product size restrictions
