Investment Casting

Investment casting is a manufacturing process in which a geometric wax pattern is coated with a refractory ceramic material, which then hardens into the shape of the casting. The wax is then melted out and replaced with a molten metal that takes on the shape of the wax pattern.

SurfacePrep supports investment casting by supplying rare earth elements and precision powders such as mullite, yttria, erbia, and zirconia for the investment process. View our refractory materials for investment casting here. To divest, or remove the ceramic coating, we provide water-jet cutting, wheel blasting, and air blasting. The finishing process can then be accomplished via wheel or air blasting, coated or bonded abrasives, vibratory finishing or super polishing, or parts washing.
