I ordered the Rio Cold Mold kit (part # 701041) so I could make
molds to inject wax into for lost wax casting.
I found an inexpensive, used wax injector on Ebay that works great.
I’m having trouble making the molds to inject wax into and filling
them with wax.
I can’t find any info online on how to do this. Making a one-sided
mold is easy, but that’s not what I need.
Basically, the stuff is too flexible. When I inject wax into the
mold, the wax shoots out the joint between the two halves, so the
mold isn’t filling up.
I’m also thinking I need to add a passage for air to escape in a
more planned manner, much like sand casting?
Any tips or links would be very helpful.
Thanks in advance!
