Molten material is elevated into a mold cavity and subsequently pressure is brought to bear on the molten material in the mold cavity substantially immediately to solidify the molten material under pressure. The molten material is tapped from a reservoir of molten material below the surface of the molten material to minimize exposure to air of the molten material and transferred to the mold cavity without a downward flow or a pouring of the tapped molten material.

Method of molding articles to minimize shrinkage and voids

The apparatus which pushes or elevates molten material into a mold cavity. The apparatus further includes a reservoir and a shuttle for transferring the molten material from a reservoir. The shuttle and reservoir assembly permits molten material to be elevated upwardly into the shuttle from the beneath the surface of the molten material to minimize or eliminate pouring and thus turbulence and pores in the final product. The final product is free of cracks and laminations, and is smooth and nonporous.
