A customer from the highway lighting industry approached Keats to reel-to-reel stamp and form custom phosphor bronze spring contacts.

We designed and built tooling to reel-to-reel stamp the .032″ thick, 1.00″ long and 1.075″ wide contacts. Then, the pre-tinned #510 phosphor bronze contacts were formed and specially packaged on reels. Throughout the entire process we held tightest tolerances of ±.005″.  50,000 of the contacts were delivered weekly to the client’s location in Mexico.

To learn more about this project, please see the details below. For more information about all of our other services please contact Keats.
