How Links to Metal Chains Are Made

How Chains Are Made

Engineering and Architecture (previously) shared an interesting clip that shows how links are formed and then connected to make a thick metal chain. It all starts out from a single piece of metal coil.

Like knives, forks, and spoons, metal chains start out as an enormous metal coil, which is fed through a series of machines that use incredible amounts of force to strengthen, cut, and then shape the metal into durable pieces.
