Foundry Manual, 1958, is an update to the 1944 Foundry Manual

The section on designs/features to compensate for shrinkage problems/weak transitions is something everyone who deals with metals should read and understand.  Most of the same rules also applies to plastics injection molding.

You may not have to directly deal with designing a cast piece and how to minimize sink, cracking, distortion, etc but the same general  principals apply to many other types of metal fabrication including forgings and fabrications.  

And...once you understand aspects of shrinkage you'll start driving everyone crazy by examining all those injection molded pieces that you run across to see how the designer made his compensations.  People will start to think you have a screw loose but it'll just be an interesting puzzle that they don't understand.
