Investment Castings problem -- surface defects caused by ...?
Folks,
I sent some very nice waxes off to be cast in sterling, but a few came back with surface defects. My casting guy says it's because the cast pieces were "too heavy." I think it was a problem with the investing technique. What is your diagnosis? I posted pictures at www.eliasbing.com/surface_defects.html. Thanks, Paul |
