Company Profile:
We run a small engineer’s office located in Germany near the Frankfurt airpor and we are working on improving fabrication technologies mainly but not exclusively in the field of extrusion. In general we are focussed on:

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
Developing totally new unique techniques to extrude 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.
Giving licences for our various patented technologies

Our patented Membrane Die Technology (MDT) can be used in slit dies and in feedblocks to produce sheets or cast films. Our patented Flex Ring Technology (FRT) can be used to produce pipes, profiles, blown films and extrusion blow moulded parts with improvesd qualities.

To find mor detailed information on specific technical topics please visit an push the buttom publications!

Most of our developed technologies are patented. We offer our techniques world wide by 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.

The more experts say: “that is impossible!” the more we are interested to testify that it will be possible neverthless!

Improved extrusion technology

What we offer:
Improved downstream equipment for extrusion processes. Unique extrusion dies and feedblocks with adjustable flow channel geometries for all extruded products (sheets, cast and blown films, pipes profiles and extrusion blow molded articles). We have patented technologies fort extrusion dies which allow for a sensitve fine tuning of the flow channel geometry while the process is running. This hepls to reduce thickness tolerances(sheets, films, pipes and also individual coextruded layers) or to improve the thickness distribution of profiles or extrusion blow molded parts.

1. What is your area of expertise or know how?
2. What type of product or service is being offered?
3. What can it be used for?
4. What are the main advantages of your solutions over other solutions? (Faster, cheaper, easier to install and/or maintain, etc.)

What are we looking for:
We are looking for companies which are interested to take advantage of our technologies to improve their product quality and in the same time reduce production cost.

We will give all necessary technical instructions to implement the technology on the lines of interested companies.

Our technologies are tailord for companies which produce extruded products.
