Benchmark for Thin Walls
Netstal-Maschinen AG, Näfels, Switzerland, has its sights set squarely on the market for thin-wall packaging. Over the eight days of the trade fair, an Elios 7500 fitted with a 24+24 stack mold will produce over 43,000 round lids with a part weight of 2.8 g per hour – in a cycle time of 4 s. In its Elios 7500 high-performance machine, Netstal has succeeded in producing a 7500 kN clamping unit with electrical movement for the thin-wall packaging sector. Here, the centrally aligned 5-point dual toggle lever ensures optimum introduction of force into the center of the mold installation space and thus uniform distribution of the clamping force. The large pillar distance and generous opening stroke facilitate the installation of stack molds or simple molds with large cavities.
The Elios 7500 marks the beginning of a new series of machines that will shortly be supplemented by other variants with lower clamping forces. The hydraulic injection axis is driven by means of two highly dynamic servo valves that guarantee high acceleration values, injection capacities and precision control characteristics during the injection and holding pressure process. The two-valve technology supports a flow rate of up to 2 x 550 l/min, with a maximum response time of 11 ms. With injection speeds of up to 2200 mm/s and acceleration values of up to 20 G, the Elios delivers impressive specification values. However, these dynamics do not entail a loss of precision: the finely tuned digital controller ensures high positioning accuracy and shot weight consistency.
