Investment casting, also known as lost wax casting, is a precision casting process that has a rich history spanning thousands of years. Renowned for its capability to produce intricate and complex metal parts with high accuracy and a smooth surface finish, this method is particularly favored for small to medium production runs where tooling costs in other casting methods may be prohibitive. Despite being more time-consuming compared to some other casting methods, the precision and quality of the final product often justify the investment.
