Custom sized aluminium enclosure required

[BillTodd]

Have a look at Penn Fabrication's Module stage box system

A couple of lengths of their corner extrusion and a few plates of aluminium and bob's yer uncle...

I was trying to find 300 x 100 x 3.2mm ali box section but no one does it that size in ali only in steel.

machining it out of 1.75" ally plate is a possible, but its £25 worth of ali. However if you plunge cut it all the way through with a 10mm cutter at least you'd end up with an approx 280 x 80 remnant which is useful; then make top n bottom out of 4mm plate.

Another option is to make it up from 4mm plate and weld up the corners... then machine clean

Gosh that's brave, how are you going to hold it down and stop it bending away from the tool/galling once the temper has gone :naughty:

32mm deep doesn't exactly lend itself to small internal corner radii and the spec is too loose. Sounds like an invitation either to do a lot of drawing and not get the job, or chop up £25 worth of stock and then get told it's all wrong. I can see why he's having problems finding a volunteer :whistling:

Well, strangely enough, I was looking into ali welding for another problem and i came across Durafix which might do the job. Anyone used it?

I bought some but haven't tried it yet. May be one of those you buy which look useful but never actually use :naughty:

Your local waterjet shop should be able to sort that, probably for cash if you supply your own material. Base would need to be removable as said before, internal radius 0.5mm min and width of cut 0.8mm so you get back a nice lump to make something else out of. Our customers often get us to rough pockets in 50mm stainless just so they can use the 'pocket' for another job. Better than turning it into swarf!
All the best.
