horizontal spraying on surface of circular parts.
Hi All,

Will there be any concern when spraying horizontally on surfaces of an circular parts? I have a project to spray on 100 pcs of circulars surface using HVOF.

   
Thanks


Patrick

RE: horizontal spraying on surface of circular parts.
The hard part of your project will be holding the parts stationary so they do not move. Your fixture must be at a lower height than the surface you are coating to avoid bridging. Otherwise, you will spray them just like any other flat pieces.

RE: horizontal spraying on surface of circular parts.
We send some parts out to Curtiss-Wright for HVOF spray on really small parts (about 2" L X W X H)...

From what I understand, they set the parts in a rectangular cast, and pour a silicone mold compound around the parts until the level of the silicone is right up next to the spray area (face).

They can process batched of ~50 of our small parts at a time in this way.
Basically they end up with a block of cured silicone with a bunch of parts embedded in the block with just the spray area exposed.

They say they can also blast the parts with the stuff, without having to repour.

May be more to it than this, but I thought it was a creative solution!

Regards!
