Eliminate injection nozzle leaks easily

Injection presses undergoing unmanned operation and large machines with obstructed views of the nozzle area can benefit from a device that detects leakage of melt at the nozzle tip.

Disc (top) connects to controller (bottom) to detect resin leakage.

Nozzle leakage is detected when leaking plastic contacts a sensor disk that encircles the nozzle. Upon detection the control box emits an audible alarm as well as activates a relay. In addition a "Status" LED reflects the current state (Red = Alarm, Green = OK).

Device developer Cincinnati Process Technologies says the leak detector can reduce machine down time, eliminate major plastic build-up, eliminate costly heater band and thermocouple replacement, and prevent plastic fires. The device can operate in environments up to 700°F. The device is also designed to fit different nozzle tip sizes and different sprue bushing depths.-[email protected]
