Working with engineers at the University of Applied Sciences in South Westphalia in Germany, Kistler has developed a new system to optimise the residual cooling time of an injection moulding process in order to lower the cycle time.
By determining mould cavity pressure and the surface temperature of a moulded product, the new system can automatically determine the residual cooling time.
Hence the system dispenses with the need for empirical setting of the injection moulding machine or the use of a cooling time formula.
In addition to the automatic cycle time calculation during mould sampling and optimisation processes, the system can 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 necessary minimum.
