I have written a piece of software to help mold designers, tooling engineers, moldmaker, toolmakers, and plastics professionals do their work in a faster, easier manner. It is available for a free 5 day trial period. This software is an incredible time saver for doing common mold engineering, machining, and production calculations. It is also a great resource for material properties (metals), a hot runner checklist, galvanic table, surface finish comparison tables, and much more.
Think of the time it will save you.
Please try it, you are under NO OBLIGATION TO BUY IT AT ANY TIME.
