Induction curing coating

Objective Curing a coating on both sides of an aluminum piston at a rate of 1” (25.4mm) per second
Material 4 aluminum pistons weighing 1lb (.45kg) each, 3.75” (95.25mm) dia and 2.5” (63.5mm) high
Temperature 225 ºF (107.2 ºC)
Frequency 6 kHz
Equipment • Power of 70 kW induction heating system, equipped with a remote workhead containing three 26.8μF capacitors for a total of 80μF
• An induction heating coil designed and developed specifically for this application.
Process A three turn channel coil 19” (48.26cm) long is used to anneal 4 pistons running though the coil with a distance of 6” (15.24cm) between centers. The parts run at a rate of 1” (25.4mm) per second and the 4 parts reach 225 ºF (107.2 ºC)
and are annealed in 40 seconds.
Results/Benefits Induction heating provides:
• Hands-free heating that involves no operator skill for manufacturing
• Ideal for in-line production processes because of its ability to produce repeatable, rapid and accurate heating cycles
• Improved thoughput
