Mold Cavity Pressure Shows Process and Quality O.K.!

Kistler: For over 30 years cavity pressure has been the process parameter of greatest importance in evaluating molding conditions. It is not for nothing that experts regard this variable as the fingerprint of injection molding.

The curve of the cavity pressure for a particular process and molding is just as distinctive and unmistakable as the human fingerprint. It uniquely identifies the quality of each and every component. Deviations from the optimum are clear indications of fluctuations in the process that lead to molding defects ranging from incomplete mold filling to flashing or dimensional discrepancies.

Predominantly used for optimization and analysis of the injection molding process in the initial years, cavity pressure measurement is now synonymous with every molding achieving the required quality through 100% monitoring of volume production, and with rapid, systematic start-up of processes without significant initial reject rates.

Cavity pressure sensors for any conceivable materials and mounting situations, simple sensor mounting, patented single-wire technology for quick and reliable cabling of molds, convenient multichannel cabling for connecting the sensors, and the CoMo Injection monitoring system type 2869B… with its multiplicity of functions: these are the modern tools used to routinely take and exploit this fingerprint.

Such 100% inline testing ensures 100% reliability for the molder and 100% high quality for the customer.
