Stupid question about manufacturing

Sorry for the totally unrelated question but if anyone can help me feel less dumb, I sure would appreciate it.

How are these cases made?

Extrusion of hot metal with a cookie cutter cone?
Looks like it’s made from one piece (holes cnc’ed after I suppose).

Im at a lack of words here to google anything significant.

TIA

Sorry I didn’t find a misc, unrelated, offthewall, AMA, etc category for this subject.

It is called sheet metal.
See Fusion 360 sheet metal workflow.

Edited: oh, sorry, 2:33 am, woke up to see this with dim phone screen, I see this wrong. Extrusion is right.

Hi @xavier.bury
That is indeed an aluminium extrusion - and yes, the holes in the flanges are machined after extrusion.

Not sheet metal.
I’d guess an extrusion process.

That’s an aluminum extrusion - here’s a good description with more details on the process

Pressed Sheet metal this would require separate parts top and bottom (This has a name too - which escapes me).

Thanks very much for all the replies!

This answers a miriad of design questions I had - like how do they make these Al cpu coolers for example (Some are cnc’ed post extrusion)…

You guys are the best!

I find this book a useful resource for questions like this one:

Bought! Thanks very much! I know a bit of a lot about manufacturing and design but still know nothing!

I really like this book:

Thanks! Not sure I need this one yet… but in the queue!

This book (Making It, by Chris Lefteri, Jessica Spencer) has 288 pages. It is intended for designers. As such, it deserves B grade. I like its style, but I dislike its hand-made drawings and omissions.

Mainstream industrial manufacturing is one of my specialties, so I prefer more professional books:

Handbook of Manufacturing Engineering and Technology, edited by Andrew Nee, 2015 (3491 pages)

Manufacturing Engineering and Technology, SI, by Serope Kalpakjian and Steven Schmid, 2023 (1313 pages)

Materials Science and Engineering - An Introduction, 9th Edition, by William Callister and David Rethwisch, 2014 (990 pages)

700 € ?

what about the 10th edition?

It’s cheaper if you search manually in the hardcover!

Good comment! I am not going to get it in the near future because I am far too busy to read it. It has “companion book”: Materials Science and Engineering: An Introduction, 10e WileyPLUS NextGen Card with Loose-Leaf Print Companion Set

I think we’re past academics - that book would be gold yesterday but today we find what we need so much easier with the web. Read all about it and keep going… But this book is a great ref to anything made in masse andor with manufacturing quality!
