An apparatus for finishing patterns and core boxes which are used under abrasive conditions and in production operations. The invention concerns the formation of an electroless nickel plating on at least the surface portions of the patterns and core boxes which are subject to wear because of repeated contact with molding and core forming materials. The electroless nickel solution is contained in a holding tank comprising a large inert plastic structure supported by surrounding insulating walls. The plastic tank is removable so that a clean tank can be utilized at all times thereby increasing the efficiency and effectiveness of the nickel plating operation. A circulating system including a heat exchanger and filter means is employed to provide maximum efficiency with respect to the use of the plating solution.
