In another life, I was a tool and die maker. I literally guarantee you that you'll spend 100X more (labor, tooling & frustration) trying to mill a bronze plaque, only to have it turn out looking poorly. You'll have tons of tool marks to polish out, and you will not attain the background texture you desire.if we want to produce something like this plaque, (16 x 24 ish) can we simply purchase a blank & do the engraving on our cnc or one of our milling machines?
(we have the equipment, but i really don't find the time to use it often)
Yep...sand casting is a very old process. What's even more amazing is how the patterns are created using a photo polymer. Some patterns are still hand-set using letter forms. Bas relief patterns are typically hand-sculpted from clay or polymer.I've never heard of blank bronze plaques. That's why I said C A S T. These things are created with first creating a mold and then the hot bronze is poured in and once cooled taken out, cleaned up and painted or cleared. Ever heard the saying 'broke the mold' ??
