Note: Annealing a copper wire connector (crimp)

Objective:

Heating a copper wire connector to 1400 ºF (760 ºC) 

End Product:

Copper connector

Equipment:

  • Ambrell EASYHEAT 8310 LI, 10kW 150-400 kHz induction heating system equipped with a remote heat station containing two 1.0 μF capacitors
  • A single position three-turn pancake induction heating coil designed and developed specifically for this application 

Materials:

Various copper wire crimps (connectors)

Temperature:

1400 ºF (760 ºC)

Frequency:

390 kHz

Testing:

It was determined that the three-turn pancake coil was best for providing the right amount of heat to anneal the connector effectively. The wire connectors heated in 1.7 seconds or less.

Benefits:

  • Speed: The proposed process met the client’s time objectives

  • Versatility: The client wanted to be able to heat parts of various sizes, which was achieved with a concentrator coil

  • Lab expertise: Given that this is a new process for the client, Ambrell’s lab expertise proved very valuable when creating the process
