Working on a little project and need to fill in a few 8mm holes. The aluminium itself is about 6mm thick.

Would prefer to be able to anodise it after completion but if not possible maybe powder coat it.

About 20 or so of the holes need blocking up.

 
Be easier and cheaper to make a new part from some 6mm aluminium sheet than to get that anodised or powder coated to a decent level

Or you could skim fill sand and paint
 
Fill and paint or make again I'm afraid. The only way you can fill and anodise that I know of is to Ali weld it.
 
Not a great help but just a heads up you wont be able to re-anodize it after filling it. I have plugged jobs at work with only slightly different graded Aluminium and it anodizes a different colour to the rest of the part.

exactly that putty is 40 quid new part much cheaper.

Where would I / could I get a new part made?

This seems to be machined out of a solid piece of aluminium. 3 cm tall in around the edges. Just to buy an aluminium block 60cm by 25cm by 3cm would cost quite a bit. Then to measure it all up and have milled etc would add up.
 
ok i thought u were doing it yourself. ignore.

wont the guys that powder coat it fill it too ? or you doing that bit ?

I wanted to fill it myself, perhaps roughly and then get it finished/prepped by powder coaters.

Basically, the original fan holes are for 120mm fans and are too far spaced apart. I've have cut out 2 x 180mm blow holes closer together but still have some of the original small holes on the outside which I would like to fill.
 
Dude, that part is not milled from 3cm of aluminium. It's a sheet that has been put in a CNC machine and then folded after the holes have been drilled.

The company I use at work is called GS Precision, who will do that sort of thing for you if you can provide drawings (or maybe a sample), but I expect there are some much closer to home.

You're after steel fabricators (will get aluminium in for you if necessary).
 
The temps used in powder coating are too high for most resins, and that which you have linked to will not anodise (and won't withstand temps). As others have said, plugging with aluminium weld would work, but also probably won't anodise properly.

Your best bet is to plug it with a bog standard low temp resin or filler and paint it or find an aluminium extrusion of similar dimensions and start again from scratch. Not sure that that part is folded, as the internal corner rads are apparently far too small for aluminium (>2 x thickness).

Just buy a 1mm sheet and use it as a veneer, anodise that and glue/rivet/bolt it to the face of that and drill it from the other side using the actual piece as a template it'll look cosmetically exactly how you want then.
