ABSTRACT:
A molding apparatus includes a bottom platen, a bottom mold portion carried by the bottom platen, and a top platen overlying the bottom platen and the bottom mold portion. The top platen includes slots extending therethrough for receiving a molding material. The molding material is to be gravity deposited into the bottom mold portion. A top mold portion is carried by the top platen and is moveable between a molding material loading position and an article forming position. An actuator is coupled to the top mold portion for moving the top mold portion between the molding material loading position and the article forming position. The molding material loading position corresponds to when the top mold portion is non-overlying the bottom mold portion so that the molding material can be gravity deposited therein. The article forming position corresponds to when the top mold portion is overlying the bottom mold portion for molding an article.
