Introduction to Investment Casting
Investment casting, also known as lost – wax casting, is a precision manufacturing process with a long history. It involves creating a wax or plastic pattern that is an exact duplicate of the desired part. This pattern is then coated with a ceramic material to form a mold. Once the ceramic is hardened, the wax is melted out, leaving a cavity in the shape of the part. Molten metal is then poured into this cavity. After the metal solidifies, the ceramic mold is broken away, revealing the final cast part. Investment Casting
Investment casting offers many advantages. It can produce complex and intricate shapes with high precision and excellent surface finish. It is suitable for a wide range of metals and alloys, including stainless steel, aluminum, and titanium. This process is widely used in various industries such as aerospace, automotive, medical, and machinery manufacturing.
