Automatic Optimisation of Mould Residual
Cooling Time Reduces Cycle Time.
Experience shows that in 70 % of injection moulding
processes, the cycle time is 20 % longer than necessary
reducing productivity of the entire process.
In co-operation with the University of Applied Sciences in
South Westphalia, Germany, Kistler has developed a completely
new technique based on the mould cavity pressure and the
surface temperature of the moulded product. The new system
can automatically determine the residual cooling time making
the empirical setting of the injection-moulding machine or the
use of a cooling time formula unnecessary. The new system
is an option for self-optimising demoulding systems using the
smart Type 5155A charge amplifiers and can be fully integrated
into the injection-moulding machine. In addition to the automatic
cycle time calculation during mould sampling and optimisation
processes, the system will control the residual cooling time
during the active production process. This ensures optimum
part geometry irrespective of process fluctuations and keeps
the cycle time to the minimum necessary.
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.
