CoMo Injection Basic - the Cost-Effective Introduction to Monitoring of Injection Molding Quality

Cavity pressure measurement stands for 100 % part quality through 100 % monitoring of
large-scale production in injection molding, and means fast, focused start-up of processes
without significant reject rates. To provide injection molders with a cheaper point of entry to
this technology, Kistler has developed the process monitoring system CoMo Injection Type
2869B0… as a basic variant. It will be on show for the first time on Stand 10F04 in Hall 10
at K 2010, the world-leading International Trade Fair for Plastics and Rubber to be held
from the 27th of October to the 3rd of November, 2010 in Düsseldorf.
As a 4-channel monitoring unit for piezoelectric pressure sensors, the very reasonably priced
CoMo Injection Basic offers four inputs for piezoelectric pressure sensors. It visualizes the
injection process, carries out quality assurance monitoring of the maximum pressure reached
in the cavities, and controls, via a digital output a device such as a reject diverter or a robot,
which separates the parts evaluated as defective.
The functionality of the CoMo Injection Basic can be enhanced on a modular basis with the
software upgrades Type 2806A…, right up to the full scope of the standard system CoMo
Injection Type 2869B1… . Upgrades include the integral, box and trapezium evaluation
objects, additional digital outputs for separation of rejects from each cavity, real-time
thresholds for switching functions, or the possibility of exporting data to the Manufacturing
Information System CoMo MIS Type 2829A… .
Pressure sensors and the multichannel cable used for CoMo Injection Basic are fully
compatible with the already introduced 8/12-channel monitoring system CoMo Injection.
As with all CoMo injections, operation and visualization of the CoMo Injection Basic is
accomplished with a choice of the optional 12,1" TFT color touch display Type 5629A3 or
via Ethernet using a standard PC.
