Induction Annealing Brass crimping

Objective To anneal a small area of an electrical contact for crimping
Material Brass female spade electrical contact with single transverse loop at end 0.5h(12.7mm) long, 0.25h(6.3mm) wide and 0.03h (0.8mm) thick, 1000oF (538oC)heat paint
Temperature 1000oF (538oC)
Frequency 300 kHz
Equipment . UM-30AB-UHF induction heating system, equipped with a remote workhead containing two 1.0uF capacitors for a total of 0.5 uF
. An induction heating coil designed and developed specifically for this application.
Process A one turn hairpin coil is used to heat the electrical contact to 1000oF (538oC) in 1.5 seconds. The contacts are in strips at 0.75h (19mm) centers and will run continuously at a rate of 50f (15.24m) per minute.
Results/Benefits Induction heating provides:
. Hands-free heating that involves no operator skill for manufacturing
. Pinpoint accuracy
. Consistent results

Electrical contact with 1000°F (538°C) temperature paint

Induction Heating is so precise that only the very end is heated to the desired temperature and melts the 1000°F (538°C) temperature paint
