New high Resolution Sensors for
Low-Pressure Injection Moulding.
Low-pressure techniques such as injection-compression
moulding, foaming and in-mould decorating have been
gaining in importance as methods for enhancing
Industrial application of these techniques, however, is more
complex than standard processes. Mould cavity pressure
measurement provides practical help for mould sampling,
large-scale production monitoring or for quality documentation.
To meet the special requirements of low pressure moulding
techniques, Kistler has developed new sensors with a resolution
four times higher than standard sensors and with a measurement
range of 0 to 200 bar. With front diameters of 2,5 mm and 4 mm,
the new sensor dimensions are equal to those of standard
sensors allowing existing moulds to be easily upgraded.
The sensors are use with single-wire technology and are
compatible with standard cables and charge amplifiers,
allowing major savings in mould engineering and maintenance.
The sensors with product numbers 6177AE (front diameter 4
mm, sensitivity 45 pC/bar) and 6178AE (2,5 mm, 10 pC/bar)
are available now.
Kistler Instruments is one of the worlds leading manufacturers
of piezoelectric and piezoresistive precision sensors covering
acceleration, force, pressure and torque. Established in
Wintherthur (Switzerland) in 1957, Kistler is represented in over
50 countries and has subsidiaries in Germany, France, Italy, UK,
Japan, USA, China, Korea and Singapore.
Heavy investment in research and development, 15% of staff
worldwide are engaged in research and development, has
generated a number of innovations using piezoelectric,
piezoresistive and capacitive techniques to provide solutions
to numerous force, pressure and acceleration measuring problems.
These innovations include the world's first commercial quartz sensor,
two-wire constant current technology to integrate sensors with
microelectronic circuitry, high-temperature pressure sensors for
use up to 400 deg C and three-component force measuring sensors.
