Not sure, but it seems to me it would have to be brief enough to only affect the surface to prevent the whole thing from deforming…and if that’s the case then it would disproportionately deform thinner sections of the part…not sure
@Kirk_Potter , wouldn’t that be similar to an acetone vapor bath?
What temps do these nozzles have to stand? I am intrigued by the possibility of casting them out of zamak. The finishing step would be threading and reaming the bore to a consistent diameter.
@Daniel_Joyce , I’d stay away from zinc, as the operating temps are lower than aluminum. IIRC, I believe people stopped using aluminum nozzles due to softening at temp. And Zamak has lower operating temps than aluminum
@Eric_Moy - Ok, is an acetone vapor bath what is done normally? I’ve seen a process of light sanding and applied heat used to smooth the surface of acrylics. This process obviously would be difficult or impossible to use on thin layers/walls. Does the acetone vapor require a rapid rinse, or is a slower reaction?
@Kirk_Potter , I’ve never tried it, but from what I read, it’s really slow, no rinse should be needed as the acetone evaporates. Try looking out up on YouTube
Aluminum loses temper at even moderately low temps. So not surprising.
@Eric_Moy I will do that. You guys are awesome! I appreciate everyone’s input. I hope that I can offer equally valuable input to others. Thank you!
