here is one of our old presses... we have three of these:
and here is one of our new presses:
these are rated at 10-15 tons.
To UnionNine: yes, we heat to 480 degrees for branding, and 220 degrees for foil stamping. the dies are all 7.8mm thick with a 4mm geometry. Cycle times for branding are about two seconds.
if you are doing the branding by hand, I recommend a arbor press with a quick release. remember: smaller geometry features will lose their heat faster than the big ones, so be sure to have a thick (3mm+) backing to maintain an even heat. If you need to stamp multiple parts, I suggest a heater block. You can find them, or make one.
