The efficient replacement of flame/gas furnace adhesive curing with induction-based curing has recently been demonstrated by UltraFlex Power Technologies. The company - a leading manufacturer of advanced digitally-controlled induction heating solutions - has performed the demonstration for a customer looking to increase productivity and perform the curing process on-site.
The test set up involved heating carbon steel pipes with OD between 100mm to 180 mm (3.9 - 7 inch) and wall thickness 10-20mm (0.39-0.78 inch). Carbon composite part had been placed on the external wall of the pipe. The goal was to affix the part to the pipe using adhesive epoxy.
The customer required that the induction system used for this heating scenario would be mobile and lightweight so the composite parts placement could be done onsite and a target production rate of 60 pieces per day / 5 pieces per hour could be achieved.
UltraFlex engineers estimated that an UltraFlex induction heater from the UltraHeat S/Air series would be most appropriate for this heating. UltraHeat S/Air is a portable, air-cooled induction heating unit that is perfect for applications with low temperature required (less than 500°F/ 260°C). The unit has a programmable temperature profile featuring multiple steps of the ramp and hold times. Once the process is pre-programmed, the operator can start a heating cycle by just pressing a button and the induction system will automatically perform a full heating/holding cycle.
In this case, the system had been programmed with 2 steps: ramping from room temperature to 200 °C (392°F) as fast as possible being step 1, and holding the temperature for 15 min until the epoxy is completely cured as step 2.
The heating process had been performed by placing the workpiece inside the induction heating coil and starting the program. A heating blanket was used in the process, to prevent damage to the dry cable coil.
The evaluation of this induction heating proved the excellent results achieved. All process requirements had been met and along with cutting down the time taken, the customer would also benefit from significant cost savings. The heating would be completely safe for the operator, with no specific environment needed or operator equipment required to perform it.
