Oddly satisfying ASMR footage shows springs being mass-produced at a factory in China.

Powerful mechanical arms hammer out intricate rhythms as they twist, jab, and cut pieces of metal protruding from a central hole to form a specific shape.

The metal is unwound from a spool behind the machine before being stretched taut across several gears and cut into different configurations.

Finished springs then drop pleasingly into boxes under the computer-programmed industrial machines.

Fenny, a staff member of the Winner Springs Factory in Guangdong province, said the same machines can also work the metal to create garden staples, fishing hooks, and even paper clips.
