Introduction to Investment Casting
Investment casting, also known as lost - wax casting, is a manufacturing process in which a wax pattern is created, coated with a refractory material to form a mold, and then the wax is melted out. The mold is then filled with molten metal, which solidifies to form the final part. This process is highly valued for its ability to produce complex and precise parts with excellent surface finish. It is widely used in various industries such as aerospace, automotive, medical, and jewelry.
