NADCA, for all practical purposes, controls all the public funding in USA for die casting research. NADCA has supported the researchers who have produced work which violates basic physics laws such as Brevick from Ohio State University (research work about the critical shot sleeve velocity). I have informed NADCA about these research works years ago and to my great astonishment NADCA continues to support these researchers (for example, NADCA is still sponsoring Brevick's research on plunger velocity). Why?
This book lists some of researchers who produce erroneous or/and poor research work, such as Al Miller from Ohio State University, Nguyen from CSIRO and many others. Would NADCA continue support their research? You will be the judge.
Perhaps they will ask you, ``How can everybody be wrong and only this newcomer be right?'' Ask yourself the following questions and make your own conclusion: Do you know of anyone who knows how to correctly calculate any of the die casting process parameters, such as plunger diameter, gate area etc.? Even better, do you know anyone who know hows to calculate the actual profit (or loss) of their die casting production? Do you know of anyone who really uses calculations to get improved casting and is successful?
Consider this: Doehler Jarvis, up to two years ago, was very active in NADCA research. They participated in NADCA committees and also took an active role in the research done by NADCA supported researchers. Guess what happened to the biggest die casting company in the world?
