Question on clarity / surface finish specifications
Question on clarity / surface finish specifications
(OP)
This is related to thread712-847.
We're designing a part where appearance is of high priority. Being run from acrylic. It's partially 'frosted' and the other part needs to be 'high polish' clarity. Could someone tell me where I might find reasonable information on how to fully specify a section that is "frosted" and similar information on "high polish" SPE-SPI's don't help a lot, as the plates we have are black ABS, I need the same information for transparent material.
Thank you much,

RE: Question on clarity / surface finish specifications
I think 'polish' may be the wrong term, as these are high rate of production parts, so individual polishing would be rather laborious. We need a way to specify a certain surface finish to be maintained for clarity and also the finish for the frosting area. Direct communication with the molder won’t be a problem, but if the tools get moved to a different vendor then we may run into trouble in the lack of specifications.

Characteristically, no post molding operation is necessary other than an optical coating process.

Polish finish is usually specified as "mirror" finish.
