Each curly cord we manufacture is a little different depending on the specifications provided to us by the client and the application where the cord will be deployed. A variety of different size conductors, fillers, and other materials make up the inside of all cables. But the process for creating a coil cord has to take into account the need for flexibility, which in turn, necessitates mitigating friction within the cord and utilizing durable materials. If you’re super curious and want to see the process first hand, we’ve put together a video of a worker at our production facility in Tanggu, China hand-making a coil cord. The process for this type of coiled cord is pretty straightforward. The worker will insert a piece of rod into a special motor and then tightly secure the cord to the rod with powerful clamps. A foot pedal activates the motor which spins the rod and allows the worker to tightly wrap the cord around the rod. The wrapped rod is then sent to a special oven to be “cured”. After a short time setting in the oven you have a flexible, durable curly cord ready to stretched and retracted hundreds of thousands of times.
