Abstract
A pressurization control unit for use in a gas assisted injection molding process includes a frame and a gas inflow conduit located on the frame. A gas pressurization device is secured to the frame and is in fluid communication with the gas inflow conduit. A gas storage device is secured to the frame and is in fluid communication with the gas pressurization device. A gas outflow conduit is located on the frame with the gas outflow conduit being in fluid communication with the gas storage device. A valve is provided in the gas outflow conduit for selectively allowing an outflow of the pressurized gas from the gas storage device. A control apparatus is located on the frame for controlling the operation of the gas pressurization device and the valve.
