Why don the hinge pins fall out?
The hinge pins are press fitted into the case while the case is hot, so as the case material cools, it compresses around the pins. Since the pins are bigger than the slot, they cannot fall out or be pulled out. Plus the hinge pins have a center block stop to prevent the pins from being pushed out by force once they are installed. This added security feature of the hinge pins prevents any potential of the hinge coming loose or the case falling apart.
