Tooling information, alloy properties, tolerances, GD&T, design guidelines, quality assurance provisions and more.
The material presented in this video is intended as an update on features in NADCA's Product Specification Standards manual - PUB-402. This manual covers specification, design and production guidance for both users and manufacturers of conventional high pressure die castings.
Revisions for this edition include: updated die casting die specification checklist; additional guidelines to increase die life; alloy composition and properties of company specific alloys; additional data for zinc alloys at temperature; EN specifications and chemical compositions for aluminum alloys; expanded zinc cross reference specifications and chemical compositions; clarified parting line calculation terminology; additional miniature die casting die materials; information on small metal savers and bumping ejector pins; and updated commercial practices to include compliance with laws and intellectual property. New, improved and updated photographs and line drawings have been added throughout.

Transcription from the video highlight:
"Welcome to the North American Die Casting Association video news and information. Every three years, the NADCA product specification standards for die casting is revised to update the information in the publication. I want to share some of the highlights from the 2018 revision of the NADCA product specification and standards for die casting.
In the 2018 revision of the publication, one of the things that we did was we took a look at our section on process material selection for a product recyclability. As we move forward in trying to build a greener world, something that is more environmentally friendly, instead of just looking at what can be recycled, we need to take a more holistic approach and take a look at the entire life cycle of a product, of a component of a product, even.
So you have a vehicle. That vehicle is made up of many different components. Where those components come from and where they go after their use is finished has an impact on the environment and it has an impact on what that product is going to do after it is done with its use. So instead of just looking at recycling, now this section looks at the entire life cycle. It takes a look at what the benefits of using secondary material over primary material are, and to wrap it all up, it takes a look at what the advantages of die casting as far as environmental friendliness go.
Another section that received a massive overhaul in this revision was the engineering and design tolerancing section. So there were many parts of this section that have been rewritten to make it easier to understand, to make it more fundamentally sound. So we've gone through, we've taken a look at that, we've taken a look at how does it read, how does it make sense? So there's been a lot of work done on that as well.
And then finally, in the quality assurance section. Quality assurance, it has a section on computer modeling and simulation. A lot of those images were starting to look a little dated as we know as anytime you talk about technology, technology advances very quickly, and so do the images. So a lot of those images have been updated to reflect more of the newer simulation models and show you what those look like, and also show you how those compare to what you can expect to see in an actual die casting. So you see this image here and you can see that you have some air pressure that's showing up in the computer simulation on the bottom, and a casting was made with those same parameters, and you can see a little bit of the blistering on the surface from that air pressure.
So that's just a kind of quick little update on what the 2018 revision of the NADCA product standards publication has. So hopefully you get a chance to take a look at it, read through it, there's a lot of good information in there. Thank you very much.
