Hi John, I believe I meant it can be a problem if you go past the
overall time recomended when investing. I am Presently Using ORO Vest
as an investment and they recommend that you are done investing at 9
minutes and to move your flasks off the machine quickly.
We invest 6 4x7 flasks at one time, and we had problems moving the
flasks off the machine quickly … ( We have about 15 seconds to move
all 6) I bought many heavy plastic Pizza pans and cut away an area of
the pan where the pipe goes through the top of the nvesting table.
Now, What we do is put the 6 flasks on the Pizza Pan and when the mix
is ready to pour, we move the pizza pan with all 6 flasks onto the
table. When the Investing is done in 9 minutes, it takes us 5 seconds
to move all six flasks at one time.
What we accomplished by doing this is that we eliminated the
investment cracking problem we occasionaly had on some flasks that
were moved individually closer to the 10 minute mark. This investment
cracking would look like a flash of metal around the top of the tree
and is mostly caused by moving the flask onto a drying table too
slowly. The Pizza Pan fixed the problem.
Your other question was about using wetwash , and I just replied on
Orchid at length about it’s benefits and what to watch for as far as
Hey folks on Orchid, I have to say that John Henkel Is a very
knowledgeable person in this field. He is an excellent mold maker and
caster as well and other than myself ( Racecar Jewelry Co.) he is one
of the few caster/ mold makers I would recommend . I have met john
at a few of the machinery shows over the years .
Best wishes to all.
