Thank you have been building dies for over 35 years and never got laid off. Or ever out of a job. Take a lot of pride and if it wasn't for us we wouldn't have what you see around us 🗿

@@davidrockey7190 I'm an automation engineer(PLC/SCADA/Instrumentation) but started out in food & beverage on design/build projects for the likes of Anheuser Busch, Coca-Cola, Ocean Spray etc. Had lots of good times with the mill-wrights. I was one of the few engineers they would work with because they knew I loved fabrication. I've even had union mill-wrights in New Jersey(those guys are born not liking engineers) hand me their tools to help get a conveyor aligned. And that's saying something because my predecessor mysteriously had a toolbox jump off of a catwalk and land beside him. He was a jerk where I had a lot of respect for the trades. I'm hoping economics dictates that manufacturing moves back to the USA. But DC and Wall Street continue to sell out manufacturing for a few shekels.

Thanks for your comments. The video was just intended to be a basic explanation. Unfortunately we cannot comment on the draw formulas as they may not apply in every situation and some of this info is proprietary. We would suggest you search “drawn cup blank reduction percentages” to find some of that info on Google.

@WisconsinMetalPartsInc thx for replying. I understand. Like I said, I only have 2 years left for retirement. The material specs were aluminum kilt. 0.0089 thousands of an inch. I know each material varies. Thx again.

The reduction percentages depend upon the stock thickness and the number of draw. For example , the component I'm making is 0.8 mm thick requiring 3 draws. 1st reduction 42%, 2nd 23%, third 18% . You'll find formulas and charts in die design handbooks.
