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.
