Aluminum cas cover jig

[DSM's 4 life]

I made an attempt at replicating oem 1g CAS cover. Stamped from aluminum on a press I made and wood molds. Keep getting wrinkles. Any ideas?

You need stiffer molds with tighter clearances most likely. I would try doing steel reinforcement around the outer flange section, sort of like a very large washer. The top looked decent in that second picture so that might get you a better flange as well.

What about a little heat or dry ice maybe.
Just throwing out ideas.

Heat will soften it, but the post about stiffer dies and more rigid press was more applicable. Once you have this, you'll need to bring up the force if you're still getting wrinkles.

Your male tool needs to be sharper or longer to take the strain out, you could also make the sheet smaller to crinkle less and clamp it down a tad to also stop it as much, but your working with pressing aluminum into wood so you gotn2 issues straight away! Aluminum and wood!

What grade aluminum is it? And how thick?

What about material thickness and speed of the press? I know little to nothing about this type of metal working, but those two combined with proper forms from the second post seem the most important.

Prolly need to clamp the sheet and press it in. What material thickness and hardness?

I'll show this to my dad, he is a sheet metal forming guy. He's building an aluminum car body from scratch. If you are interested in this kind thing check out like metalmeet.com

I think your right on with this I stumbled upon this on another site the pice I'm pressing the depth into needs to be held tight and allowed to slowly draw into it.

The stock cover looks good when its polished.

It's steel, how do you polish it

Steel can be polished up just as good as ALU or stainless, it takes a good amount of work and mops and abrasive blocks but it does well, you need a good entendre bench grinder and the moping wheels and time! Lots of time

I'm assuming it needs to be clear coated after to prevent rust.

Yes of course, it will come out nice when done properly

Exactly like that!

Good stuff wish I knew about this before. Not a total loss I'm sure I'll use the press for something some day.

I got a polished theme going on that's why I wanted it shiny. Is the process simular to that of almuinum? I've never polished steel.

Yes it's the same. I use the same wheels and same polishes. Just takes a little longer.
