Smallest Model in Hybrid Injection Molding Machine Line Optimized
Netstal has redesigned drive components of the hybrid ELIOS series, resulting in reduced dry-cycle times, lower energy usage, and a smaller machine, with the smallest unit in that line—the 460-ton press—now shorter.
Netstal said it was able to lessen the dry-cycle time of the smallest model in its hybrid ELIOS series of injection molding machines, while also reducing the power consumption of the 460-ton press by redesigning elements of its drive. Specifically, Netstal says it revamped the clamping unit’s actuating elements and completely eliminated the hydro-mechanical portion of the drive to create a 100% electric drive train.
In doing so, Netstal says it not only reduced the energy consumption of the ELIOS by 7 kW, but it also quickened the machine’s dry-cycle time by 0.1 sec to 1.4 sec. A further benefit: eliminating the hydro mechanical components for operating the toggle lever also shortened the machine by 450 mm (approximately 18 in.).
Netstal says for the higher clamp force models of the ELIOS line, the existing hybrid drive provides the optimum combination of speed and energy efficiency. These machines feature an electrically driven double-gear rack and pinion and a synchronous hydro-mechanical actuator to build clamp force. Depending on the model, the dry-cycle time range between 1.4 and 2.2 seconds. The ELIOS series, which ranges in clamp force from 460 to 1000 tons, targets high-speed thin-wall applications. Netstal is part of the KraussMaffei Group of companies.

Recycling Terminology Can Be a Minefield, So We Should Tread Lightly
Loose propagation of terms like “recyclable” and “compostable” has already brought down government regulations on labeling. The plastics and packaging industries should take that to heart with other recycle-related language. Like “monomaterial” for example.
