Optimised cooling of injection mould cuts costs

A system that determines the optimum cooling time for moulding tools, developed by Kistler Instruments, can reduce cycle time by 20%, producing typical cost savings of £35,000 per annum per machine

A new system that automatically determines the optimum residual cooling time for injection moulding tools, developed by Kistler Instruments, can reduce cycle time by 20% (twenty per cent) producing typical cost savings of £35,000 per annum per machine.

Working with the University of South Westphalia, Kistler ran tests on 700 (seven hundred) moulding tools that proved the cycle time in 70% (seventy per cent) is at least 20% (twenty per cent) longer than necessary.

The new technique uses mould cavity pressure and surface temperature of the moulded product to control the residual cooling time to ensure optimum product geometry and cooling time irrespective of process fluctuations.

Using the new Kistler Type 5155A Smart Charge Amplifier, the self-optimising demoulding system can be integrated into most injection moulding machines to provide automatic control of residual cooling time for maximum production efficiency and minimum wastage.
