Investment casting, also known as lost-wax casting, is a manufacturing process in which a wax or plastic pattern is coated with a ceramic shell to create a mold. The pattern is then removed, leaving a cavity in the ceramic shell that is filled with molten metal. Once the metal solidifies, the ceramic shell is broken away to reveal the final metal casting. This process is commonly used to produce complex and intricate parts with high dimensional accuracy and surface finish.

Investment casting foundries typically specialize in producing metal parts for a wide range of industries, including aerospace, medical equipment, defence, automotive, and more. These foundries use a variety of materials, including aluminium, titanium, stainless steel, and super alloys, depending on the requirements of the part.
