QUALITY MOLDING powered by Kistler

The New 100 % Quality Seal for Injection Molding Processes

The new "QUALITY MOLDING powered by Kistler" seal sends a clear signal of zero-defect cavity pressure-based injection molding.

The 100 % QUALITY MOLDING seal stands for zero-defect injection molding processes – particularly for the production of electrical, medical and automotive applications. The core technology responsible for this achievement is cavity pressure-based process and quality monitoring enhanced by process control and hot-runner balancing. All sensors and systems used during this process are independent of material, machine manufacturer, mold and peripheral devices.

Cavity pressure-based QUALITY MOLDING is not dependent on the polymer material because the principle of cavity pressure measurement has been tried and tested for 35 years and can be validly applied to every material grade. Cavity pressure-based quality monitoring is not dependent on the manufacturer, construction, drive concept and control of the injection molding machine but is suitable for every model. Quality monitoring is not dependent the mold because the significant cavity pressure is undisputed no matter which mold is used. Cavity pressure-based quality monitoring is not dependent on the maker of peripheral devices because Kistler systems transmit standard signals to control reject gates or robots that separate defective parts.

Dr.-Ing. Oliver Schnerr, Head of Business Unit Plastics explains the benefits of the new quality seal: "With 'QUALITY MOLDING powered by Kistler' molders send a clear signal that they monitor their injection molding processes seamlessly and use the potential of process control to detect malfunctions during the production process and to actively separate potentially defective parts. With QUALITY MOLDING, these molders demonstrate that cavity pressure measurement guarantees 100 % quality. With 'QUALITY MOLDING powered by Kistler', molders send a clear signal to customers that they decided for seamless process monitoring and quality without compromise. Production with Kistler sensors means quality 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 holistic 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.
