Abstract: An injection molding system and method of operating the system are disclosed. The system may include a hopper, a barrel configured to receive injection material from the hopper, a screw disposed within the barrel, and a mold defining a mold cavity configured to receive the injection material from the barrel. A pressure-balancing conduit may connect the mold cavity and a rear end of the barrel and be configured to allow air to flow from the mold cavity to the rear end of the barrel. A mold valve may be disposed between the pressure-balancing conduit and the mold cavity and a barrel valve may be disposed between the pressure-balancing conduit and the rear end of the barrel. The method may include opening the mold valve and injecting a material into the mold cavity from the barrel.
