induction preheating aluminum wheels for spray painting
Description
induction preheating aluminum wheels for spray painting
Objective: This spray painting application requires pre-heating the material. Additionally, there is a requirement that the material must not cool below a certain target temperature prior to the spray.
Material : Customer-supplied parts
Temperature :275 ºF (135 ºC)
Frequency :8 kHz
Equipment :
DW-MF-70kW induction heating system, equipped with a remote workhead containing three 27 μF capacitors for a total of 81 μF
– An induction heating coil designed and developed specifically for this application.
Induction Heating Process
A multi-turn combination helical/pancake coil is used. The 22” aluminum wheel is inserted into the coil and heated for 30 seconds to a temperature of 275 ºF. When heating is halted, the part remains at or above 150 ºF for 108 seconds, fulfilling the target heat requirement.
Results/Benefits Induction heating provides:
-Uniform heat distribution over the wheel
-Precise control of heating and pattern
-Efficiency; reduced energy costs
