Abstract
A method and apparatus for mixing ceramic powder and binder to form an injection molding formulation is disclosed. A container made of wear resistant plastic such as polytetrafluoroethylene, nylon or polyetheretherketone having an inner surface which forms a mixing cavity is used. A mixing ball having a radius of curvature less than the radius of curvature of the inner surface is added to the mixing cavity along with the ceramic powder and binder. The container is heated and shaken to form an injection molding formulation. In one embodiment the mixing ball is made of an outer plastic shell surrounding an inner metallic core. In an alternate embodiment, the mixing ball is made of the ceramic material being compounded.
