Gaining energy advantages through
Netsal 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 energy efficiency 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 the machine
represents by far the largest proportion in regard to energy consumption.
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. The Eco Powerunit attains
unprecedented energy savings with hybrid injection molding machines. The
following properties make a major contribution 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 can be
made compared with conventional hydraulic machines. If an allelectric
machine is used, an additional efficiency advantage of around 20 percent is
attained.
Energy advantages when producing PET performs
One other example of the very high energy efficiency of injection molding
systems from Netstal are the special machines – designed for maximum
productivity – for producing preforms for PET bottles. Netstal supplies these
machines under the names PET-LINE of the Netstal brand and PETForm of
the KraussMaffei brand for different output rates. A comparison with
competitors reveals that our systems are well ahead, a fact proved

conclusively by the following example of a direct comparison measurement.
The PET-LINE 3500-6600 from Netstal and the rival machine produced the
same number of preforms during the measurement operation (10.5 g twist
off 25/30). The impressive result of the test was an energy consumption of
0.28 kWh/kg during production on a PETLINE. This represented an energy
saving of 25 percent compared with our 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 energetic
advantage over rival systems. The clamping unit in the PETForm systems is
vertically arranged. This has far-reaching impacts on 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 demolding gripper,
only very small masses have to be moved during demolding. That's because
the post-cooling required during preform production is autarkic and must not
be moved into the clamping unit. The vertical design ensures that the
preforms need not actively be demolded using energy, but can “drop” with
guidance.
Energy efficiency is not just a current buzzword
It is foreseeable that energy costs will rise still further in future. In addition to
material costs, the proportion of energy costs will become the second most
important cost factor. Netstal is devoting its entire innovative capacity to the
development of systems and solutions which ensure maximum energy
efficiency and maximum productivity. Strictly according to the motto: “Low
energy, high performance”.
