What amazes me is how this steel can be pressed into these different shapes and not rip. I am glad this has been figured out or otherwise car styling would be really boring.
The metal can rip, tool makers make use of somthing called draw beads and fine blanking techniques to help support the steel and help it flow into the desired shape and surface finish. They use ait bolsters or cushions on the bottom die to achieve duel action to prevent the top die and punches from stressing the steel.
One thing you don't see often is the actual dies up close. I think it's really neat to see how much more there is to the die itself than just the trimmed piece that is the result.
I remember the Camry that was made in Japan, with Japanese parts before 2002. It held together and was practically indestructible, especially the mechanical part. I owned two, my wife wrecked one of them and my son the other. The ones made locally after that are no different than Chevy, Dodge, Hyundai or Ford.
Automobile die making really doesn’t use “molds” for the rough cast iron die…forming, flanging, trim, and punch surfaces are now machined but used to be all hand worked in the old days(23 yr journeyman diemaker). We still hand finish critical surfaces.
@@tpaine121 Also u need 5 tools to make 1 peace of body part ( depends on the part ofc ) . yea and cnc machine this days cant finish tool in that quality u need, so you have to hand finish form or active surfaces on tool , im working on cnc machine and we making parts for pressing tool then other guys building it together and testing it in press that is operated by workes not robots . Said in short term , whole proccess is way more complicated it takes 2 years to make one working tool
I'm a tool and die maker and have 5 year experience in hot stamping. I'm looking for a better opportunity in your company. How can I apply for the vacancy.
