Introduction to Lost Wax Steel Casting
Lost wax steel casting, also known as investment casting, is a highly precise and versatile manufacturing process. It has a long - standing history and is widely used in various industries such as aerospace, automotive, medical, and machinery. The process begins with creating a wax pattern of the desired part. Multiple wax patterns are then assembled onto a wax tree. This assembly is coated with a ceramic shell, which is built up layer by layer. After the ceramic shell is hardened, the wax is melted out, leaving a cavity in the shape of the original wax pattern. Molten steel is then poured into this cavity. Once the steel solidifies, the ceramic shell is broken away, and the final steel casting is obtained. This method allows for the production of complex shapes with high dimensional accuracy and excellent surface finish, making it a preferred choice for many high - end applications.
