Precision casting, often referred to as lost-wax casting or investment casting, is a process that involves creating a wax pattern of the desired part, which is then coated with a ceramic shell. Once the shell hardens, the wax is melted and drained away, leaving a precise mold cavity. Molten stainless steel is poured into this cavity to form the final product. This technique allows for intricate designs and fine tolerances while minimizing machining requirements, which can reduce production costs and time.
