This document discusses different types of mechanical joints used in manufacturing, including fasteners, swaging, press fitting, and integral hinges. Swaging involves bending and crimping plastic parts to join them, either with or without heat. Snap fits use locating and locking features molded into the parts themselves to mechanically join components together, and are commonly used in toys, appliances, automotive parts, and electronics.
