If the box's contacts aren't enough to keep the plates apart
then penetration is just a natural side effect (what else would
be expected?).  The only question is why the box doesn't keep the
plates apart.  I'm guessing you're applying a force to bring the
plates together and it's too strong to be countered by the
box's soft contact.  Try lowering the force and/or playing
with ERP/CFM.
