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

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.
