  • Rotary plasticator ram injection machine
    Patent number: 4557683
    Abstract: The output of a plastic or polymeric material processor is fed through a three-way valve to an expandable chamber in a barrel having a ram therein. When the chamber has a predetermined charge the valve is shifted to direct the output of the plasticator to an accumulator. Operation of the ram injects the material into a mold cavity and thereafter the valve shifts to direct the combined output of the plasticator and the accumulator to recharge the chamber.
