Investment Casting, also known as Lost Wax Casting, is a precision casting process used to produce complex metal parts with excellent dimensional accuracy and surface finish.
In this process, a wax pattern is created and coated with multiple layers of ceramic material to form a mold. Once the ceramic shell hardens, the wax is melted and removed, leaving a cavity into which molten metal is poured. After solidification, the ceramic shell is broken away to reveal the finished part.
