There is a lot of support missing when you suppress the green injection molding part. With the molding, the fingers around the magnet are supported by a layer of PPS that is in compression between the two fingers, as well as the layer of material that develops hoop stress to support the magnet.nWhen the injection molding is suppressed, the support retracts to the central core of the electro metal plate and the fingers are free to flex out. This causes high stress due to the small wedge angle on the magnet, and there is no layer on the outside to support the magnet.nYou need to add a blend fillet to this edge of the injection molded match this fillet on the electro metal plate.n
