By using induction-based curing for this process and thanks to the precise, digital control on the temperature of the heated parts, the manufacturer would achieve a time- and cost-efficient process that would ensure no damage to the paint.
The time-efficient and precise induction curing for automotive parts has recently been demonstrated by UltraFlex Power Technologies. UltraFlex - a leading manufacturer of advanced, digitally controlled induction heating solutions was approached by an automotive parts manufacturer looking to optimize an existing curing method for SUV steel suspension parts. The induction heating process was aiming at heating steel bars to a maximum heating temperature of 230 °C (446°F), so an adhesive would then cure. The entire process had to be completed within less than 95 seconds.
Considering the temperature and the material specifics, UltraFlex engineers recommended an UltraFlex induction heater from the UltraHeat W series as most appropriate for this scenario. UltraHeat W are advanced, cost-effective 5-15 kW Induction Heating Systems, utilizing the latest switching power supply technology. They feature adaptive digital phase control providing very efficient operation in a wide frequency range. UltraFlex induction heaters are digitally controlled and allow for target temperature to be set and automatically observed.
The heating process was started by ensuring a 1.25" (3.17 cm) coupling gap from the bottom of the induction coil to the part and a 0.25" (6.35 mm) coupling gap from the edge of the coil to the part, to avoid overheating. At output power of 10 kW, it took 60 seconds to have the curing process completed - which was way less than required by the customer.
By using induction-based curing for this manufacturing process and thanks to the precise, digital control on the temperature of the heated parts, the manufacturer would achieve a more time- and cost-efficient process that would ensure no damage to the paint of the parts. When implemented on the line, the process would guarantee consistent, high-quality results, with no dependency on the operator skills. Last but not least, due to the lack of smoke and noxious emissions, this would be a completely safe process - safe for the operator, safe for the environment.
