Dear Prototypers and Tooling Specialists,
We are searching for experience in tool-production with the integration
of Rapid-Prototyping-Techniques.
In our special case we want to test different ways from the RP-model to:
1) Deep-drawing tools for sheet metal forming and
2) Building of tools for injection-moulding.
We have tested a way with the following steps:
- Building a RP-Mould (negative part of the tool)
- Casting with a special concrete material and with resins
- Demoulding of the tool (positive tool)
- Testing the tool with aluminium on a special rubber-pad-forming-press
The tests where successful for the production of up to 100 sheet metal
parts.
(See paper at
http://www.biba.uni-bremen.de/projects/hyprform/shemet.html)
Now we want to know more about other ways of Rapid-Tooling with RP.
Perhaps you are interested in an exchange of information with us.
Is there anybody out there with experience in the mentioned subject
(especially for sheet metal forming) ?
We are an Institute at the University of Bremen, Germany, and our work
areas are industrial technology and applied work science. We are working
with RP techniques since 1989.
For more information about us look at our WebSites:

Yours sincerely, Juergen Bauer
