best way to manufacture tapered tubes?
(OP)
Hi,
I am working for a small engineering company with less with 20 employees.
We are trying to manufacture a some number(~5000pc) of tapered tubes(~10" length) in China.
They are going to be either stainless steel or aluminium. We haven't decided which way is the best.
I was thinking about die casting aluminium tapered tubes and anodizing them
but soon realized that cast aluminium cannot be anodized due to high silicon contents.
Now I am looking for alternative options. Maybe we are going to power coat cast aluminium tubes or use stainless steel.
I am not sure which way is the best to go...
I cannot tell you exactly what they are going to be used for but tapered tubes are going to be fit in each other like those plastic cups.
Can anyone give me any advice on this matter?
Thank you!

You will be told that yes, they can do it, no problem. This is SOP with Chinese companies. 8 months later you'll be cursing them and cursing yourself for not doing a little more due diligence. I have some top notch work done in China, don't get me wrong, but you need to be able to specify and verify every aspect of your component in the process.
It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.

What kind of dimensions are these 'tubes'? I assume fairly thick walled if you're considering casting them.
