Hello list members,
at the BIBA (Bremen Institue of Industrial Technology an Applied Work
Science at the
University of Bremen) we are testing sheet metal forming dies made by
Rapid Prototyping
Technologies.These dies are tested on a rubber pad forming press.We´ve
got a laminated
die which consists of mounted sheet blanks. In order to smoothen the
dies´surface we tried
to putty it with a polyester putty and finished it by grinding. But this
material peels off the die
after some draws. Now we are looking for a sufficient material and a
usable method of
puttieing the die.
Has anybody gained experiences on this field?
Please, contact us, if you know a certain method or material in order to
smoothen the

kind regards
