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.

6. Finishing The aluminum casting often involves additional processes such as machining, finishing, and surface treatment to enhance its durability and appearance.

4. Sustainability Aluminum casting is considered a sustainable manufacturing option. Recycled aluminum can be used in the casting process, which reduces waste and energy consumption. Additionally, aluminum components are often recyclable at the end of their life cycle.
