Less injection moulding rejects

The CoMo Injection system from Kistler Instruments is widely used to ensure minimum reject rates by monitoring and controlling in-cavity pressure in large scale injection moulding production. The launch of the new CoMo Injection Basic brings the same zero reject capability within the reach of lower volume production. The new version will be especially useful to moulders producing large, high value items, such as car bumpers, where even a small proportion of rejects can hit profitability, says the company.

CoMo Injection Basic provides an interface to four in-cavity, piezoelectric pressure sensors to monitor the maximum pressure reached in each cavity. It also controls, via a digital output, a device such as a reject diverter or a robot, which separates any parts evaluated as being defective.
