Ettlinger at
Fakuma 2017:
Yet More Melt
Filtration
Performance and
Quality
Ettlinger Kunststoffmaschinen GmbH,
manufacturer of high performance melt
filters and injection molding machines for
high shot weights, will show a brand new
generation of melt filters at the
upcoming Fakuma 2017.
Ettlinger filter systems have already set
important efficiency benchmarks on several
occasions in the past. The new generation
which will be premiered at the Friedrichshafen
exhibition will raise the bar even higher
in every respect. The first few months of
practical experience with pilot customers have
confirmed an up to 28% increase in throughput
for the same filtration quality and the same
ultra-low melt losses. Users profit from more
productivity when recycling contaminated
waste plastics from industrial or consumer
sources. Furthermore, Ettlinger filter systems
can in future be very easily integrated into
Industry 4.0 environments.
Volker Neuber, Managing Director Ettlinger: “Waste
streams vary enormously in quality, and the
ability to supply high quality recycled polymer at
competitive prices is more of a challenge than ever.
Our latest filter generation provides the answer: our
existing series are already extremely efficient but
we’ve now achieved a new landmark.”
The new Ettlinger filters work with a rotating,
perforated drum – the principle already familiar
from the ERF and ECO series: there is a continuous
flow of melt through this drum from the outside
to the inside. A scraper continuously removes the
contaminants that are held back on the surface and
feeds them to an exit screw or discharge shaft. This
enables the filter to be used fully automatically and
without any disruptions over a period of weeks
and months without having to replace the screen.
The advantages of this design are the constant
melt pressure, ultra-low melt losses – recognized
throughout the industry – and good mixing and
homogenizing of the melts. Whereas the ERF series
is optimized for separating foreign particles from
heavily contaminated polyolefins and polystyrenes,
the ECO series is ideal for filtering polyolefins, PET
and PA as well as recycled material containing up
to 1.5% contaminants during the extrusion of films,
sheets and other semifinished products.
High-volume machines for 100 kilo moldings
Although Ettlinger will not be showing its srm series
of injection molding machines for shot volumes
up to 180,000 cm³ and component weights up
to 120 kg live at the Fakuma booth, the latter is
nonethel ess expected to be a popular port of call
for manufacturers of such products. Their defining
feature is the structural separation of the melt
processing and injection units, which makes them far
more energy efficient than conventional machines.
Ettlinger’s injection molding specialists will be at
hand throughout the exhibition week to discuss the
specific problems of this niche segment with visitors
and explore potential solutions to current issues.
