Precision investment casting, also known as lost-wax casting, is a manufacturing process characterized by its ability to create complex shapes and maintain tight tolerances. The process begins with a master pattern made from wax. This pattern is coated with a heat-resistant ceramic material to form a mold. Once the mold is set, the wax is melted away, leaving a cavity that is then filled with molten stainless steel. After cooling, the mold is removed to reveal the final product.
