To add to Bruce's previous posting:
As noted, the process works fine but your problem will be that the parts you cast in this
silicone mold
will be too small unless tolerances don't matter. Wax shrinks quite a bit.
Many waxes will work but to get consistent dimensional results you must have good
repeatability
of the injecting pressure, temperature of the wax and temperature of the mold-- just as in
injection molding of plastics. Depending on your part configuration some waxes may be too
brittle or too soft.
