The electrically driven five-point toggle system of the ALLDRIVE has been specially configured for the dynamic behaviour of the electric drive, allowing for rapid, highly accurate movements resulting in the reduction of the cycle time. Due to the functional principle of the toggle, it is possible to dispose with the pressure build-up time which is necessary in the case of hydraulic mould clamping to compress the oil during the build-up of clamping pressure.
Thanks to their independent operation, in conjunction with the flexible programming and control possibilities of the SELOGICA system, the ALLDRIVE electric axis drives offer greater potential for optimising the reduction of cycle times.
The separation of the plasticising procedure from the cooling time can also contribute to a reduction in cycle time. For applications in which the cooling time alone is insufficient for dosing and therefore the dosing time dictates the cycle time, it is possible to perform dosing beyond the cooling time via an independent electric dosing drive without increasing the cycle time. However, in this case it is necessary to use a shut off nozzle. The cycle time between the mould movements can be shortened with the use an electric ejector, which ejects parts precisely and dynamically.
The utilisation of the potential offered by electric drives, however, is dependent on its support from the relevant moulding technology. For instance, it is also highly important that moulds are able to support the faster cycles particularly when considering the use of cores and controlling the mould temperature.
