Thanks in advance... I am an avid reader of this newsgroup (and occasional contributor), and know how much knowledge exists in this group.
I have some parts that are being extruded and will be hardcoat anodized. They are posts that attach to an aluminum base to batch parts in between processes... a robot will load/unload them from this pallet. The surface finish on the posts should be smooth so as not to scratch the parts if they graze them going in/out of the pallet. I am making
100 of these pallets, which works out to 3000 of these posts...I am worried about surface roughness... I have seen some parts after anodizing that are pretty smooth and some that were somewhat rough. Is there any special preparation to ensure an Ra 32-40 microinch (give or take) finish?
It seems that the anodizing process would inherently produce a somewhat rougher finish than the bare metal as it creates a layer of oxide... is there any suggstions for what finish I should spec on the bare extrusion?
Any other suggestions along these lines... I am new to the extrusion game. Any other coating suggestions? I need something that is hard, durable and rather inexpensive. I have looked into Nyflor, a Teflon-impregnated coating that is laid down after nickel, but the cost of the coating was 5x more expensive than the total part cost w/ hard-anodize!
Thanks a million...
