Precision casting, often referred to as investment casting or lost-wax casting, is a method that allows for the creation of intricate parts with outstanding dimensional accuracy. The process begins with a wax pattern that is coated in a ceramic material. Once the ceramic hardens, the wax is melted and drained away, leaving a hollow shell. Molten metal is then poured into the shell to form the desired component. After cooling, the ceramic shell is removed, revealing a precision-cast product.
