There is a perfectly good wax press commercially made by Limousin
Apiculture in France, and exported worldwide.

It is claimed to recover 99.5% of the honey, leaving only near dry wax
cakes and sends the honey back to the extractor sump.

They also have a video of their setup showing it in operation.

I've just bought one but have not used it yet so cannot yet confirm its
performance. It seems to be an adaptation of a commercial grape press
for the wine industry.
