Interesting manufacturing processes/techniques?

Hi all,

I’m looking into various interesting or different manufacturing processes, so not the standard milling/spray painting/molding etc.

Thought about hydroforming and anodizing, but they’re not really all that special.

Any thoughts for something a bit different and more interesting?

Ta, Duane.

Bit bored there Duane? 😉

How about some EDM to get you going?

All the new 3d ‘printing’ methods are pretty interesting, especially now people are using metals not just plastics

Charge bikes had some pictures of 3d printed titanium drop-outs. Have a look on their Twitter feed.

That is wicked. Those Louis Vuitton shoes are amazing. No wonder they cost such a lot…

Ultrasonic welding.
Cryogenic treatment.

i always liked explosive cladding

The charge bikes twitter feed was good today.

Water jet cutting is worth a look

Plus I know you said not milling but true 5 axis is pretty cool:

Neotecman flashless stamping.

i was just going to post the daishun vid thats quite possibly the best demo of what a 5 axis machine can do

I was always impressed with castings.

I’ve always wondered how they make Hollowtech cranks. Anyone know?

Friction stir welding

Selective laser sintering

Cold Spray

DMD

Incremental sheet forming

Hydrographics

hollowtech is forged over wax

Ac282 + 1, was going to suggest a few of those, friction stir welding is ace.

Will add superplastic forming, that coupled with diffusion bonding lets you blow up ti fan blades like papier machée balloons! Also, check out making single crystal turbine blades by directional cooling and the use of pigtail selectors.

Extractive metallurgy is all pretty cool too in a fire and brimstone kind of way but possibly not really manufacturing.

ECM

And you can make one fairly easily at home with a car battery and windscreen washer pump!

You can make all kinds of weird, intricate things with it.

Prob not what you’re looking for but how about some old school noodle making?

2 minutes into the vid.

Thanks for the replies all, lots to look into 🙂

Second question- standard things you see on a day to day basis, which have interesting manufacturing techniques/processes etc?

Thinking along the lines of a bike tyre, paper, took pick, etc etc.

Haha you’re just being **** lazy now! Have a look around you. I did exactly the same project in uni, probably one of my favourites

How about Carbon-Ceramic discs….

A mixture of carbon-fibres and Silicon Carbide. I’ve actually been and seem this process at the Brembo factory in Stezzano Italy 8)

I run an electron beam welder making bits for the eurofighter

Ceramic discs? I thought they were made like this…

Love the square hole milling.

Grim, you’re not at a small company nr Bristol run by a bunch of blokes who left BAe are you? Had some quality eb work done there if you are!

And as for everday objects, look up how tungsten light filaments are made. Can’t hot work tungsten wire sensibly so you have to powder form instead

No I’m at bae at Samlesbury oop north

Ah well, before I left the last place it looked like laser was going to be chosen over eb so no harm done. This thread is why I wonder if I should have stayed in manufacturing rather than going to technical consultancy

Here you go.. a bit more about it:

OOOh, my brother installs waterjet cutting machines.

And if you want a very long and laborious manufacturing process, then check out the production of a bespoke suit from fleece to finished product. Makes you realise why handmade bespoke suits cost a small countries national debt.
