Abstract
A process is provided in which a plasticized resin is extruded from an extruding machine into an accumulator into which the resin is stored by an amount which exceeds the amount required for one resin molding operation. The stored resin, in operation, is fed through a flexible hose to a supply and measuring device, such as a gear pump, under controlled pressure conditions. The resin is measured by the supply and measuring device by regulating the flow rate of the resin and is then charged into the mold cavity in a measured amount. The clamping of the mold can be effected by a clamping force less than that required by a conventional press-molding machine.
