Manufacturers may have a concern about the investment that is required for investment casting tooling. At first glance, it may seem more costly than other processes; however, when taking into account long-term considerations, it is a better investment in many cases. Tooling is the creation of a metal structure that is used to make wax patterns that are the molds that form the final castings. It is true that there may be a larger up-front expenditure for investment casting, but these tools can be used over and over. This spreads the cost over a great many castings, lowering the per part expenditure. When you also consider the many benefits and advantages of investment casting, it is a wise, long-term investment.
