Not that I'm in love with Sanders or their material but with investment
casting you really ought to look at .....What has changed in your process?
Be methodical. Ask the Department Foreman / Supervisor of each department if
necessary. Have you always used mineral oil? The same brand / quality? Did
the burnout cycle change? Heck, I could list 100's of process parameters
that might have created your problem. Right down to a new batch of
investment or a change in the investing room environment. Ask Hamilton!

  Hello all. For the last few months, we've been having trouble casting our
Sanders waxes. We've been getting blisters which are clearly from air
escaping from the models (not surface air bubbles) and flashing. We are
casting jewelry objects in sterling. The parts are always solid and have a
light coating of mineral oil. We don't use a de -bubbler. Our investment is
Kerr Satin Cast and our burn-out is entirely successful for our regular
waxes. I've always had some trouble with the blisters but the flashing is
new in the last few months. Has anyone else experienced this recently or
does anyone have any words of wisdom? Should the burn-out be different for
these waxes, perhaps?
