Casting Process

Investment Castings

Investment casting technology is a casting technology widely adopted among the investment casting manufacturers and it can also be called precision investment casting. The biggest advantage of investment casting lies in that as the investment casting has relatively high dimensional precision and surface smoothness, mechanical processing can be reduced. A small amount of working allowance is only needed for the spare parts that has high requirement, and some casting only needs polishing allowance without mechanical processing.
