Abstract

A process for molding thermosetting plastic parts in a more efficient manner involving less cost and a higher production output, includes sequentially filling molds with a thermosetting plastic material in a continuous and uniform manner, passing the molds sequentially through an elongated heating chamber, removing the parts from the molds, and returning the molds for reuse. Also, to increase the versatility of the process, a plurality of independently driven conveyor assemblies are positioned within the heating chamber so that a number of different parts having different sizes, configurations and/or material may be fabricated concurrently with one another.
