How would I get nice, crisp corners?

For small pieces, I have successfully made sharp bends by clamping the piece between two blocks and bending up the sides using a piece of plate and a vise. The bend had no option other than sharp. I used this methood to make small boxes The inner block had the dimensions of the base flange which resulted in very uniform boxes. I made heat sinks for our LED lighting out of .063" aluminum resulting in inner bend radii of less than .030" and a flat base flange. For reference, the base flange is 1" across. It is impractical, though, for larger pieces.Heat Sink .JPG
 
The link below has some good information. Most may be common knowledge to you, but it couldn’t hurt to check it out.
