Abstract
A molding system includes a plurality of injection heads each configured to inject molten polymer into a mold cavity. Each injection head has an outer body, a piston disposed within the outer body and defining a polymer chamber on a first side of the piston and a pressure chamber on an opposite second side of the piston. The piston moves from a retracted position to an extended position responsive to pressurization of the pressure chamber. Molten polymer is injected from the polymer chamber into the mold cavity as the piston moves from the retracted position to the extended position. Such systems may be used to mold relatively large articles of manufacture.
