Mould cooling time optimised automatically

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.

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.
