AUTOMATIC OPTIMISATION OF MOULD RESIDUAL COOLING TIME
28 October 2004 - Kistler Instruments

Kistler has developed a completely new technique based on the mould cavity pressure and the surface temperature of the moulded product which can automatically determine the residual cooling time, making unnecessary the empirical setting of the injection-moulding machine or the use of a cooling time formula.

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.

The system will also 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.

About: Kistler Instruments
Kistler is one of the world's leading suppliers of measurement technology. Kistler pressure sensors, force sensors and accelerometers use the piezoelectric effect for precise measurement of mechanical properties.

Kistler is a privately-owned Swiss company which develops and manufactures sensors and electronics for measuring pressure, force and acceleration.

Additionally, the functionality of electronics plays an increasing role when defining a measuring system and even more frequently, electronics in fact becomes part of the sensor itself. Most of Kistler's products have been developed in close cooperation between leading universities or research facilities and Kistler's engineers.

Investments in Kistler's research department have led to the development of new crystals which enable reliable measurements to be taken under the most extreme environmental conditions. The results of our in-depth crystal research will give us a leading edge in advancing the state-of-the-art.
