▶Conventional valve gate defects
The valve gate can freely set the resin injection timing by opening and closing the valve pin.
However, since the valve pin can only be turned on and off by pneumatic or hydraulic pressure, it is not possible to control the delicate discharge rate of injection.
In addition, if the gate is balanced, burrs are likely to occur.
If it is difficult to balance the filling with a family mold, it is necessary to use a single stroke molding method.
If the position of the valve pin can be freely adjusted, wouldn't it be possible to control the flow rate as desired, like a water tap?
Therefore, we developed a valve gate system that can control the valve gate pin at any position.
By controlling the resin flow rate, we aimed to equalize the in-mold pressure during molding.
