We run a
small engineer’s office and we are working on improving fabrication
technologies mainly but not exclusively in the field of plastics processing. In
general we are focussed on:
- Taking advantage of the SLM (3D
printing for metal parts) fabrication method in order to further improve
the processing possibilities of dies and heads (see as an example the
video of the mixing head SLM head)
- The development of unique
extrusion dies which possess an adjustable flow channel geometry so that
the melt distribution in the die can be fine tuned while the process is
running.
- Improving
existing extrusion technologies based on our own ideas (for more
information please visit publications)
- Developing
totally new unique techniques to process critical materials or to
fabricate products which still do not exist (strictly confidential)
- Developing
unique new processing methods for our customers or helping our customers
to overcome existing processing problems (strictly confidential)
- Consultancy
services to reduce production costs and to improve product quality.
Our patented Membrane Die Technology
(MDT) can be used in slit dies
and in feedblocks to produce sheets or cast films.
Our patented Tilting Die Technology (TDT) and the patented Flex
Ring Technology (FRT)
can be used to produce pipes, profiles, cables, foamed films and foamed sheets,
blown films and blow moulded parts. Severe improvements of the thickness
distribution of blow moulded parts and a significant reduction of the
production costs can be reached when using the GWDS-Technology (GWDS), which is a surprisingly easy
solution to realise a dynamic radial wall thickness programming. It facilitates
the complete blow moulding process by for instance avoiding the entire
investment in a conventional PWDS-System which was state of the art before the
GWDS-Technology came up.
Compared to the 30 year old PWDS system our new FRT technology and especially the new GWDS is much
more versatile. For example conventional PWDS systems require high-force servo-hydraulic
cylinders. They also can only have a limited number of deformation points
particularly with smaller die diameters. The GWDS comes along with a conventional
solid die and a solid mandrel and nevertheless a better thickness distribution
can be achieved than it is possible with the conventional PWDS-system. This is
valid especially for blow moulded parts which afford a very severe difference
in the wall thickness over circumference of the parison.
With Flex Ring Dies (FRD) it is possible to dynamically program the
radial wall thickness for diameters even down to 6 mm (see video).
Although nearly every existing head can be retrofitted with a Flex Ring Die
the return on investment is extremely short when retrofitting
multi-cavity-heads due to the high output rates.
Using Flex Ring Cores (FRC) the static
profiling of the core can be done much quicker and more precisely. Our latest
development facilitates the centring of annular dies. Using our Tilting Die
Technology (TDT) dies can
not only be mounted much quicker but also centred more sensitively and thus
much more precisely. For more detailed information on the whole range of our
developments please open publications or use the flags
to perhaps find publications even in your language.
Most of our developed technologies are patented. We offer our techniques
world wide by licensees (see licensees)
or by our new subsidiary Gross Meßtechnik. Fore some technologies we grant non exclusive licenses. So
if somebody is interested to use our new techniques it might be possible to get
a license. If you are interested in more detailed information please don’t
hesitate to send us an e-mail (see button e-mail) or give us a call. We hope
our information is of help for you. Enjoy our homepage and thanks for visiting
it.
The more experts say: “that is impossible!”
the more we are interested to testify that it will be possible!
