PBS is the proud manufacturer of investment casting for turbine wheels, which are one of the two main components of a turbocharger turbine, along with turbine housing. Investment (or precision or even lost wax) casting is a delicate and challenging process involves the creation of a wax pattern in the desired shape of the part to be created. This wax pattern or figure is repeatedly dipped into a liquid ceramic multiple times until it has achieved the desired size. Eventually, the mold (with the wax inside) is heated, causing the wax to melt away. The orifice from this lack of wax is then filled with molten metal. PBS works mostly with superalloys based on nickel and cobalt in order to produce a durable, reliable, and long-lasting structure. Once it has cooled, the mold is shattered, leaving behind the cast metal part.
