Ejector pin placement near snap-fit

M
0

I’m working on a small injection-molded housing for an automotive sensor, using PA6 GF30. There are two snap-fit arms inside (cantilever type), about 2 mm-thick walls. I’m not sure where to place the ejector pins without risking marks or deformation near those arms. Anyone here dealt with ejector placement on flexible features like this? Especially with glass-filled nylons that don’t forgive much?
