Serious HES derivative project proposal

Hi Cadman,

If you don't mind - can you share where you got the powder, etc. and the cost?
No problem if you can't but thought I'd ask. You can PM me if you are concerned
with the possibility of some interference with your sources, etc. TIA

Sure, glad to. They are in New Jersey and have several types of powders.

https://sciencekitstore.com/metals/iron-powders/

These are the two I chose to start with.

IRON100  10lbs for $54.00
https://sciencekitstore.com/iron-powder/

SM101 5lbs for $65.00
https://sciencekitstore.com/soft-magnetic-iron-powder/

They were delivered in heavy plastic bags inside of quart size cans, boxed of course. Fast delivery too.

PS  the calculated weight for my Samsung outer rotor iron is ~6.3 lb

Thanks again Cadman.

Just backed-off a $10K MOPA Laser purchase (wanted to speed up the
lamination cutting process) - to focus on the SMC powder forming
approach again.

Found 50 Ton hydralic cylinders on Amazon (~$100) so two of those
(opposing) should be more than adequate for >800MPa compression.
Put my CNC Mill to work machining molds and $10K worth materials
hopefully will yield better bang for the buck? 

More versatile as well - thin metal sheets are only cheap in ton rolls,
therefore a bag of iron powder at 10 lbs at $50 makes more sense!

Oh - gotta go - big black snake just went into the greenhouse...

Be careful there it's easy to fool yourself. The tonnage rating of a hyd press is the total piston force or hyd pressure x piston area. Then you divide that by the square surface area of the part being compressed to arrive at the compression force applied to the part, either psi or Mpa. Without looking it up I think 1 MPa is about 145 psi. 400 Mpa is ~58000 psi.

So for example, if you're compressing a part with 2 square inches of surface with a 400 Mpa press you're only applying 200 Mpa or 29000 psi to the part.

If you're thinking about making a hydraulic press, leverage can be your friend.
