Abstract
A molding apparatus utilizes two conventional single-injection molding machines and a rotatable disk positioned between those machines. The disk has four workstations, a first one and a second one opposite respective molding machines, and a third one at which molded items are removed. The molding apparatus has the advantages of lower cost and greater flexibility over double-injection molding machines.
