Investment casting, also known as lost-wax casting, is one of the oldest techniques and is widely favored for its ability to create complex shapes with smooth surfaces. Here, a wax pattern is coated with a ceramic material. Once the ceramic is hardened, the wax is melted away, leaving a cavity that is then filled with molten aluminum. This process allows for high detail and accuracy and is often used in industries where precision is paramount, such as aerospace and medical devices.
