Netstal Elion series with increased output
An optimisation of the dry-cycle time of Netstal Elion series models was achieved by making an adjustment to the clamping unit controller. The company states that the output can be increased even more in series production use.
The dry-cycle times of the high-performance Elion model have been reduced by up to 0.2 seconds across the entire model range. The shorter dry cycles are available for all Netstal Elion models with aXos version 8.2.0. and up. The additional speed is made possible through the adaptive optimisation of the acceleration and deceleration ramps for the clamping unit drive. The result: The maximum moving speed will be reached faster than before and can be maintained longer before the moving mould plate is harmoniously decelerated and the toggle lever mechanism seamlessly transitions to building up the clamping force – all without compromising mould protection.
However, a shorter dry-cycle time does not automatically mean a faster cycle under real production conditions. That is why the new control algorithm takes into account the potential tool weight based on the set installation height and incorporates it in the control of the acceleration and deceleration process.
High-performance solution for closure applications
The following application example illustrates what this can mean in practice: A Netstal Eion 4200 with a 96-cavity mould produces Type 29/25 HDPE closures. One closure weighs 1.23 grams. Thanks to the optimised control, the cycle can be shortened from 2.77 seconds to 2.6 seconds. The hourly output goes up from 124,750 to 132,920 closures, which equals an increase in productivity of 6.5 per cent.
