I have an interesting suggestion: laser caving. So not traditional laser
engraving, but really milling with a laser instead of EDM or milling. This
pretty new technology combines laser with depth controlled cavity making.
To get the needed CAD/CAM data, the required twisted rope should be scanned
from a model and this scan can then be transmitted to data to feed the
machine (reverse engineering).
Laser caving is possible in most steel kinds, no matter how hard. Also
other materials are possible.
We, TNO Institute of Industrial Technology in the Netherlands, have one of
the very few laser caving machines in the world, and could do this job. I
am project manager within the concerned department, so please revert if you

Onderwerp: Injection Mold needed for Jewelry
I produce plastic injection molds for jewelry, cheifly by CNC and
pantograph, and die sinking/hand engraving methods. I have a customer who
requires an injection mold for a coin frame bezel pendant that has a
twisted rope edge on the outside as is commonly seen in jewelry
catalogs...It will hang on a common twisted rope chain, about 4mm, and have
a coin about the size of a silver dollar in it. A rubber or RTV mold, or
tooling as you engineers say, will not give the level of detail he wants.
Anybody know of a way to create a cavity of the profile of rope chain to
accomplish this ( by EDM or whatever),or possibly a metalized epoxy type
mold, etc.? Anyone want to give a bid on the job? I am making other molds
for this customer, but not able to do this one.
