About Project
The plastic injection mold we chose to create was a lock and chain consisting of three main parts: the tumbler, latch, and links to form the chain. The locking mechanism uses the same principal as those found in common backpack clips
common backpack clips. The latch has flexible ends that deform around the pin on the tumbler and lock into place. The tumbler is composed of two identical square parts that have openings for the latch as well as a mating pin.
