Process Monitoring System aids injection molding QA.
Press Release Summary:
Offering 4 inputs for piezoelectric pressure sensors, CoMo Injection Basic provides injection molders with point of entry to cavity pressure measurement. System visualizes injection process; carries out QA monitoring of max pressure reached in cavities; and controls one device, such as reject diverter or robot, that separates parts evaluated as defective. Several upgrades are available, and operation/visualization is possible via 12.1 in. TFT color touch display Type 5629A3 or PC.

CoMo Injection Basic - the Cost-Effective Introduction to Monitoring of InjectionMolding 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.
The process monitoring system CoMo Injection Basic Type 2869B0xx offers a particularly costeffective point of entry to the monitoring of injection molding
Kistler will present its portfolio of products for plastics processors, moldmakers and manufacturers of plastics machinery on Stand 10F04 in Hall 10 at K 2010 - the International Trade Fair for Plastics and Rubber to be held from the 27th of October to the 3rd of November 2010 in Düsseldorf. On its own stand, Kistler will demonstrate quality assurance of injection molding of a medical part on the basis of mold cavity pressure.
At K 2010 Kistler will also be providing live demonstrations of the capabilities of its sensors and systems on nine separate injection molding machines on stands of partnering companies in Halls 10, 11, 13, 14, 15 and 16. The spectrum of applications range from the development of new methods of processing through optimization of injection molding processes to quality assurance and process control in large-scale production.
Background: Quality Assurance with Mold Cavity Pressure
The cavity pressure curve is considered to represent a fingerprint of the injection molding process. It is the most informative characteristic for evaluating the quality of the part. Deviations from the optimum curve are clear indications of process fluctuations that lead to part defects ranging from incomplete mold filling to flashing or dimensional discrepancies. As the supplier with the largest and widest range of sensors for all methods of injection molding, simple connection technology and intuitively easy to operate, networkable systems, Kistler is the only manufacturer to offer complete monitoring of injection molding from a single source. Kistler is the world's leading manufacturer of pressure and temperature sensors for use in the plastics processing industry.
Kistler Group
