btrueblood, for prototypes that sounds like a solid idea; however we are looking at 1000 part run, and won't make sense to do the molding in house. Did you spray the thinned liquid pvc? How was the adhesion to the substrate?
In my previous post about the soft coating, I was thinking of an...
Btrueblood, thanks, and I've taken a look. It seems that the pvc coat is targeted at parts where you can dip, while our part has splines on the interior. We could mask the top and bottom but the viscous nature of the PVC leaves drips and would be hard to get consistent. ... I haven't used the...
TVP, I ordered a copy of the book, and look forward to using it as a resource.
In this round of production an over molded part is going to be cost prohibitive for our start up. Does Eng-Tips have any tips on a rubbery or soft touch spray on coating? Does anyone have an idea on the longevity of...
Thanks for the advice, I contacted two local (Sacramento, CA) injection molders and will probably be working with one of those.
racookpe, thanks for the suggestion, but I over simplified the part in my original post and won't be able to find something "over the counter".
