Using new and innovative technology can be risky, but it can often be rewarding. European electric-motor manufacturers Bosch, Siemens and Volkswagen realized this in 2011 after discovering hot crimping.
For decades, these companies used machines or chemicals to strip the enamel coating off the ends of magnet wires before crimping them to copper ring terminals or sleeves. Hot crimping, in contrast, vaporizes the insulation during crimping of the wire and terminal or sleeve.
