Does anyone out there have any on injecting wax patterns
into hard rubber molds at 50+ psi?
I’m using 50 psi as a guess starting point because I believe that
would be somewhat the force needed to collapse any trapped air and
force liquid wax into the sharp mold corners to achieve a crisp
I’ve been told a long time ago it was possible by making some kind
of modifications to maybe a standard air pressure jewelry wax
injector or creating one from some type of heated pressure boosted
vessel — bulk grease gun, industrial hot adhesive applicator etc.
I’m very familar with making standard jewelry injection molds and
low pressure patterns with air over wax injectors… about 35 years
the last time I counted. And I’ve constructed hydaulic paste wax
injectors that injected into rigid molds, but those were very
specialized and mechanically elaborate machines.
Any help, info, guidance, drawing, or just a thumbs down would be
