A mold cavity-defining die assembly includes lower and upper molds adapted to be disposed against one another. The lower mold has an inner surface defining an outer side of a mold cavity and forming an outside wall of a formed millwork product produced in the mold cavity. The upper mold supports an array of core members such that the core members protrude into the mold cavity so as to define an inner side of the mold cavity and form an inside wall and interior ribs of the product such that the inside wall and interior ribs together provide sufficient surface area to ensure that the product clings to the upper mold and core members and releases from the lower mold upon separation of the molds from one another.

An injection molding apparatus for producing formed or molded millwork products includes a workstation supported on a support surface, a lower composite mold/press unit mounted upon the workstation and defining a lower portion of a mold cavity, and upper composite mold/press unit defining an upper portion of the mold cavity, and support members spaced apart from one another along the lower composite unit, movably mounted to the workstation, and extending above the lower composite unit where the support members mount the upper composite unit generally above and for movement toward and away from the lower composite unit. Either of the lower and upper mold/press units can have replaceable plates for different shaped products. The apparatus also includes actuators for the support members and releasable locking mechanisms for the upper composite unit.

An apparatus for rotatably molding a formed millwork product includes lower and upper mold parts for defining a mold cavity therebetween, a support arrangement for rotatably supporting the lower mold part about a longitudinal axis, a clamping arrangement for releasably clamping the mold parts together, a feeding unit for supplying molding material in a liquid form into the mold cavity, a drive unit for rotating the mold parts about the longitudinal axis, and a cooling arrangement for circulating a coolant medium to and from the rotating mold parts so as to control the temperature of the mold parts in view of the exothermic reaction of the molding material in the mold cavity.
