Hah, what's a reasonable price? In the distant past we ordered a ton of
extursions from here,
https://cardinalaluminum.com/
I think ordering a ton was the only way to keep the price down.
We've got a life time supply... I have no idea if their quality is still
good.
They also did some machining and anodizing on the part.

We'll try them. We want to cut/machine/anodize too.
Thanks

Probably, for 'custom' designs you have to go to a real
extruder plant that makes dies, and commit to a few ten-
meter lengths. Ryerson, MInalex look like good prospects.

Try Tendon Manufacturing in Cleveland if that is viable for you. Get ahold of Jim Moderelli and tell him Jeff sent you. He is not necessarily in sales, he is like an all around guy for them. Probably does expediting and whatever because he does go on the road and he does have skills. So that is a reasonable assumption.
https://www.tendon.com/
On their homepage of the graphics, at the top right, or third on because who knows your screen resolution, they give the info.
Actually, if you only need a few pieces and they aren't all that hard I might be able to get them out of there under the table. they do let him do that from time to time. Then all we have to pay is him.
I also got a guy very adept with Rhinoceros and Solidworks. He can probably bust out code faster than almost anyone on those. You probably don't need him though, you probably have the drawings, but if they want any significant extra charges find out why and I can tell him the problem.
It's like - how many pieces are we talking here and what do they look like ? he can do jet engine impellers or coffee pots, where does this stand in that spectrum ?

We're tired of buying stock extruded enclosures that are expensive and
poorly designed. It's time we did our own extrusions. We could buy a
truckload.
It would basically be the sides of something like this
http://www.highlandtechnology.com/DSS/T564DS.shtml
We'd make the top/bottom/ends out of flat sheets, to make it easier to
work on.
We'll ping Jim. Thanks.

Swarf? I've been bitten by metal shards from threading some holeOn Thursday, 9 May 2019 13:37:05 UTC-4, John Larkin wrote:

Hi, John:-
Be sure to talk to your prospective supplier before finalizing the design,
if you can avoid hollow shapes the cost will be lower and it may be easier
to control the tolerances, for example. I know you'd like to eliminate the
threading into open shapes, for example, because swarf can fall out into the
circuitry. It might make more sense to drill and tap solid ends on a CNC
machine, or even to press threaded fasteners into the aluminum.
Extrusions are relatively simple compared to things like plastic injection molded parts, but there are still complexities.
BTW, the extruder is fed with billets that represent so many pounds of aluminum alloy (maybe 500), so there's a related minimum quantity per run.

Sometime in the past I recall browsing the various extrusions
that were available...
there were hundreds/ thousands at each extrusion place!
thread bend;
I've got a dream of milling bath-tubs out of aluminum bar stock.
Five sided boxes with a top panel. Nice thick sides
that you can add connectors or heat sink tabs onto the
box. Say a 3" width, 2" depth to the tub. and you could
make various lengths. Like blue pomona boxes, but better.
(and hopefully cheaper.) With small companies you sometimes
have to buy a life time supply of something, to keep the price
down for your customers. (or because the something is going away,
and finding a replacement may not be possible.)

So you are thinking of a C channel as wide as your box, with short legs to
form the sides? I'm assuming you want some ribs on the sides and maybe the
bottom for stiffness and to mount a PCB along with the end and top plates?
That width is going to make it expensive and once you commit to a custom
extrusion you are locked into that size. How about just doing the sides as
an extrusion and making the bottom out of flat sheet just like the top.
That way the width can vary if needed, both sides are the same so you only
need one extrusion, and that extrusion is much smaller and thus much
cheaper. If you need more stiffness you could have the top and bottom
plates stamped or run through a bead roller to either put beads on or to put
a joggle on the sides or ends. That wouldn't be very expensive and could be
ordered in reasonably small quantities. I'm sure a real mechanical designer
would have even better ideas for stiffness, but the key is to drastically
cut down the size of the extrusion at the cost of having to screw on the
bottom of each box.
Here's the old one. It's pretty horrible.

The screw locations are inconsistent and the self-tapping screws make
shavings.

All the tapped holes would be machined in solid areas

I've always wondered how people know how long they will live to buy a lifetime supply. Or in this case, how they know how long the product will live?
