Device promotes injection moulding 'zero
defects'
Claimed to be a major step forward in achieving 'zero defects' in injection moulding, a compact device incorporates eight signal amplifiers for process optimisation, monitoring and documentation.
Building on its long experience of using in-cavity pressure profiles to monitor and control the injection moulding process, Kistler Instruments has developed CoMo Injection, a totally new system that promises a major step forwards towards true 'zero defect' production A compact all-in-one device, CoMo Injection incorporates eight signal amplifiers to be used for process optimisation, monitoring and documentation, including a fully integrated electronics and software package

Piezo-electric sensors monitor die conditions
A number of innovations using piezoelectric, piezoresistive and capacitive techniques have been developed to solve numerous force, pressure and acceleration measuring problems in dies.
This allows up to eight cavity pressure sensors to be connected to the CoMo Injection system using a single cable and plug.
This Multi-Channel Cable Technology solution reduces set-up times and minimises the risk of connection errors.
During a production run, all process data are continuously recorded and can be stored for both process analysis and quality assurance monitoring, including the production of relevant documentation.
In addition to production monitoring and control of the injection process based on cavity pressure, CoMo Injection provides one 'outputs valid' signal for synchronising with the good part/bad part separation system, the handling device or the machine input for external signals.
Eight good part/bad part channels can be used to signal to the downstream device whether the active shot complies with the quality requirements (good part) or not (bad part).
These eight channels can also be reconfigured for deployment as real-time outputs to support highly complex moulding processes.
Compared with other injection moulding process-monitoring tools, CoMo Injection offers a highly cost-effective method of minimising product rejects and maximising productivity and product quality, whilst reducing waste.
