Note: Heating lead battery terminal for removal (recycling)

Objective:

Heat a lead battery terminal to 400 °F (204 °C) to release it from plastic cover for recycling 

End Product:

Lead battery terminal

Equipment:

Ambrell 2.0 kW induction heating system, equipped with a remote workhead containing two 0.33 μF capacitors for a total of 0.66 μF
An induction heating coil designed and developed specifically for this application

Materials:

Battery terminals 0.84 in OD (21.3 mm) x 0.45 in ID (11.4 mm) x 1.3 in (33 mm) long 

Temperature:

400 °F (204 °C)

Frequency:

318 kHz

Testing:

A single-turn helical coil is used for this heating application. The lead terminal is placed inside the coil and is heated for 20 seconds. The terminal become hot enough to separate from the plastic. The terminal and plastic are separated and the lead is cleanly removed.

Benefits:

  • Controllable and repeatable heat

  • Efficient and faster production

  • Hands-free heating that involves no operator skill for manufacturing

  • Even distribution of heating
