COMO INJECTION PROCESS MONITORING SYSTEM
FOR INJECTION MOULDING .
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 optimization, monitoring and
documentation, including a fully integrated electronics and software
package. The integral web server allows set-up and display of process
parameters using a standard web browser on a PC or laptop or the
optional, dedicated touch screen monitor. An Ethernet interface allows
process data to be communicated to a production planning and control
or ERM system and downloaded to any location via the Internet.
To simplify installation, CoMo Injection uses an innovative multi-channel
connection system based on the well-proven single-wire technique to
connect to the cavity pressure sensors. 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
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.
Kistler Instruments is one of the worlds leading manufacturers
of piezoelectric and piezoresistive precision sensors covering
acceleration, force, pressure and torque. Established in
Wintherthur (Switzerland) in 1957, Kistler is represented in over
50 countries and has subsidiaries in Germany, France, Italy, UK,
Japan, USA, China, Korea and Singapore.
Heavy investment in research and development, 15% of staff
worldwide are engaged in research and development, has
generated a number of innovations using piezoelectric,
piezoresistive and capacitive techniques to provide solutions
to numerous force, pressure and acceleration measuring problems.
These innovations include the world's first commercial quartz sensor,
two-wire constant current technology to integrate sensors with
microelectronic circuitry, high-temperature pressure sensors for
use up to 400 deg C and three-component force measuring sensors.
