I recently purchsed an embossed Aluminium sign; the letters and the surrounding boarder are raised. The bottom part of the letters has got quiet a radius on it so I do not think it is pressed with a top and bottom former.
Any ideas as to what is involved would be greatly appriciated.

That might account for the radius on the base of the letters. Do you think that they use some sort of press and what material might the letter formers be ?
Some sort of press. Probably on a commercial machine the letters are hardened steel. I have used just cold rolled steel for make recesses in aluminum plate up to 1/8" and cold rolled lasts a very long time. You just can't have any really fine detail or keep the corners completely sharp.
So many questions...
I made an embossing tool out of a piece of 1" thick 6061t6 alum. I used a piece of fairly stiff urethane that was about .125" thick, pushed with a block of steel 1" thick. The aluminum was sheet, maybe .025" thick.
The art was no deeper than .08"
So many variables,
what material and how thick?
Alum presses easier than steel
How deep an impression is needed?
How fine is the detail?
My suggestion: do like I did. Try something and learn from it.
FOR EMBOSSING, I USE MY ENGLISH WHEEL WITH A FLAT DIE. I MAKE THE PATTERN OR LETTERS AND USE MY FLAT DIE ON MY ENGLISH WHEEL. IT ALSO DEPENDS ON WHAT MATERIAL YOU WANT TO EMBOSS AS WELL. THIS WORKS GREAT ON ALUMINUM OR ANY SOFT MATERIAL. TRY IT YOU WILL BE VERY SURPRISED OF THE RESULTS. HOPE THIS HELPS FOR A DIFFERENT IDEA TO TRY.
I use different materials to emboss.
I made a license plate mold with trim edge out of brass, and 6061 aluminum. I can interchange art work, and make special plates for companies. I use a 1/4" 90d urethane on the top plate and hit with limits on my 50 ton iron worker. I have seen guys use the e-wheel, pullmax machines,and h presses.
Should be pretty easy.
