Latest Patents

Kawai's latest patents include innovative designs for gas venting arrangements in high-speed injection molding apparatuses. One of his patents describes a gas venting arrangement that features a gas vent control valve, which can be closed at optimal timing and at high speed. This is achieved through an advanced combination of a control circuit and a valve driving mechanism. The control circuit connects to a molten metal sensor, sending a high voltage output drive signal to the valve driving mechanism when the sensor detects molten metal or metal splashes. The valve driving mechanism includes an electromagnetic valve linked to a pneumatic source, enabling prompt operation of the gas vent control valve.

Another patent focuses on a gas venting arrangement in an injection molding apparatus, detailing a method for venting gas effectively. This arrangement includes mold halves with a gas vent passage in fluid communication with the mold cavity, a gas vent control valve, and a detection member that generates a signal upon contact with injected material. The valve driving mechanism operates in response to this detection signal, ensuring efficient gas venting.
