Perfect rejection of faulty parts

Like many injection moulders, Barkley Plastics has been using cavity pressure monitoring for several years to try to identify out of spec parts before they get into the delivery system. However, two of the old systems have now been replaced with the latest 4-channel CoMo Injection systems from Kistler Instruments.

According to Barkley's business development manager, Matthew Powell, by monitoring all aspects of the cavity pressure curve during the moulding process, the CoMo system ensures that all out of spec parts are rejected quickly and reliably. "Because the CoMo system automatic - ally provides perfect rejection of faulty parts, it is possible to run the moulding machines in the dark with little or no supervision," he says.

In addition to monitoring the process, the CoMo system can be used to balance the hot runners, which Powell describes as a "massive bonus" that is essential to main taining consistently high quality parts.
