Runner=balloon theory -1
In the runner, the fed resin is compressed due to the gate resistance
and its pressure is stored. After the resin has been completely
fed with the screw stopped from advancing, the pressure is transmitted
to the cavity.
Now let us assume a simple model, in which a screw is located on
the rubber tube side, a balloon is used as a runner, a closed valve
functions as a gate, and a cavity is located beyond the gate. When
the rubber tube is blown, the balloon will be greatly inflated as
the valve has resistance. If you stop blowing the tube and seal
it, the balloon pressure will be applied to the valve. |
