Ambitious overmold: included suction cups?
Ambitious overmold: included suction cups?
(OP)
Hi,
I've designed some parts with undercuts allowed by soft overmold before, but never anything quite so dramatic as a fully formed suction cup. I have an application for a small (3")electronic device which will have co-molded TPU or PVC over the vast majority of the exposed surface. It would be really slick if I could also mold in some suction cups to the same material, kind of like they do for so many bath mats. Anyone tried something like this? What material spec/dimension should I be heading toward to pull that off? I haven't found a good reference guide yet.
