Precision casting, often synonymous with investment casting or lost wax casting, is a metal-forming process that utilizes a wax pattern to create a mold. The wax is coated with a high-temperature resistant material, forming a shell around the pattern. Once the shell solidifies, the wax is melted and drained away, leaving a hollow mold ready to be filled with molten metal. This process allows for intricate designs that traditional methods cannot easily achieve.
