Gaining energy advantages throughNetsal expertise
Low energy, high performance
(Naefels, 07. Juni 2012) The reduction in energy consumption has been a key discussion topic for many years.In the last few years Netstal has also paid special attention to increased energyefficiency of injection molding machines. For the benefit of customers.
Efficient
Energy cannot be generated or destroyed. However, it is possible to
convert energy into different forms. Different forms of energy occur in
connection with injection molding machines (see above photo).
Increased efficiency firstly reduces the absorbed energy of the
machine. Secondly, it increases the energy proportion which is
required for shaping (i.e. production of the injection-molded part). The
machine emissions (heat, sound) are therefore reduced.
Energy advantages of the ELION series Actual operation of themachine represents by far the largest proportion in regard to energyconsumption. Thanks to the new generation of the ELION series we have increased energy efficiency enormously. We used the leitmotif“Low energy, high performance” when developing this series.This means: Maximum performance and optimum energy efficiency.We developed a completely new power unit with this objective. TheEco Powerunit attains unprecedented energy savings with hybridinjection molding machines. The following properties make a majorcontribution in this respect:
• Recovery of kinetic energy
• Adaptive drive regulation
• Power converter network
• Optimum working point at maximum efficiency
By using the Eco Powerunit, energy savings of up to 50 percent canbe made compared with conventional hydraulic machines. If an allelectricmachine is used, an additional efficiency advantage of around20 percent is attained.
Energy advantages when producing PET performs
One other exampleof the very high energy efficiency of injection molding systemsfrom Netstal are the special machines – designed for maximum productivity– for producing preforms for PET bottles. Netstal suppliesthese machines under the names PET-LINE of the Netstal brand andPETForm of the KraussMaffei brand for different output rates.A comparison with competitors reveals that our systems are wellahead, a fact proved conclusively by the following example of a directcomparison measurement.The PET-LINE 3500-6600 from Netstal and the rival machine producedthe same number of preforms during the measurement operation(10.5 g twist off 25/30). The impressive result of the test wasan energy consumption of 0.28 kWh/kg during production on a PETLINE.This represented an energy saving of 25 percent compared withour best competitors.
We attain the high energy efficiency of our PET-LINE thanks to the
following factors:
• Electric drive unit
• Toggle lever on the clamping unit
• Much lower dry air consumption
• Vertical robot which consumes much less energy
• Energetically optimized system between drying unit and machine
Due to the vertical concept, our PETForm systems also have an energeticadvantage over rival systems. The clamping unit in the PETFormsystems is vertically arranged. This has far-reaching impactson the entire demolding and downstream process:
• Low-moving masses
• Less work during the clamping movement
• Increased efficiency thanks to vertical technology
Thanks to the vertical clamping concept and the ultralight demoldinggripper, only very small masses have to be moved during demolding.That's because the post-cooling required during preform productionis autarkic and must not be moved into the clamping unit. The verticaldesign ensures that the preforms need not actively be demoldedusing energy, but can “drop” with guidance.
Energy efficiency is not just a current buzzword
It is foreseeablethat energy costs will rise still further in future. In addition to materialcosts, the proportion of energy costs will become the second mostimportant cost factor. Netstal is devoting its entire innovative capacityto the development of systems and solutions which ensure maximumenergy efficiency and maximum productivity. Strictly according to themotto: “Low energy, high performance”.
