Any input on a suggested method of rapid tooling (inj. molds)that
would satisfy the following needs would be appreciated. This tooling
would be for sunglass frames. The lens grooves would be created by
handloaded inserts.
I have succesfully used aluminum tooling that has been CNC-ed but I
would be interested in something with a shorter lead time. I do know
about Keltool and Simeon Bojilov's powdered metal process.
Rapid Tooling Requirements (in order of importance):
-able to last for 1000 shots using Nylon
-conducive to free-form parting lines (non-planar)
-available in 5 weeks or less
-able to have inserts, cores and ejector pins added easily
All responses, suggestions will be appreciated
