Benefit of Investment Casting
Investment casting has several advantages over other methods such as sand casting and lost foam casting.
Investment casting is ideally suited to smaller, more intricate designs and provides the precision necessary to incorporate logos, product IDs and numbers onto the surface.
Unlike sand casting which requires moulds to be broken apart to divest the pattern, the investment casting process leaves only a minor parting line that is easily removed, resulting in a far smoother surface. Investment casting generally does not need much in the way of secondary processing (polishing, trimming etc.).
