    Detailed Product Description

     Dengfeng mold provide Gas assisted molding in from 2010 years. Now we can design Gas assisted mold as client's requirement. The two main control techniques for gas injection are volume control and pressure control.

    Gas injection stage

    The gas injection stage of the Gas-assisted Fill+Pack analysis is an integral component of the filling phase and provides you with the ability to specify single or multiple gas injection locations either directly into the cavity, or via the polymer injection position/s, that is, machine nozzle or runner.

    The onset of gas injection is independent of the time at which polymer injection stops, providing the ability to incorporate a dwell period between the end of polymer injection and the start of gas injection. The gas injection pressure can be set up to a maximum of 70 MPa, and can be profiled to a maximum of 100 steps.

    Gas volume control

    A preset volume of gas is injected and the gas pressure decays during the packing phase. In the case of volume control, the initial charge of gas is fixed at a particular volume for a set pressure. The gas is injected into the polymer melt by means of a gas compression ram. The gas pressure then decays as the gas expands into the melt and is held during the packing phase.

    During the holding (cooling) phase the gas maintains pressure on the polymer and in so doing packs (compresses) the solidifying polymer, compensating for volumetric shrinkage. The gas pressure also forces the outer polymer skin against the mold walls maintaining good thermal contact and ensuring that cooling periods are kept to a minimum.

    Gas pressure control

    Gas pressure is controlled during the injection cycle and can be stepped or profiled. In the case of pressure control, it is the pressure of the gas which is being controlled during the injection cycle, not the volume. This is based on the assumption that the gas pressure can affect the rate of movement of gas/polymer flow fronts. Gas pressure can be stepped or profiled during both the injection and packing phases.
