Induction Heating Application: Wire Coating removal

Objective

A client had been using resistance heating for a copper wire coating removal application but wanted to see if induction could deliver faster, more consistent results. So, the client sent their wire samples with a polyamide coating to THE LAB at Ambrell and took advantage of complimentary applications testing.

Evaluation

THE LAB determined that an Ambrell EASYHEAT^TM 6 kW 150-400 kHz induction heating system with a specially-designed multiple-turn helical coil would be optimal for this application. Testing in THE LAB proved that heating could be completed within seconds with an Ambrell EASYHEAT induction heating system. The heating time and proposed process met the client's requirements. 

Solution

Induction's speed and repeatability were the primary reasons for considering induction, and they were pleased with the lab results in both regards. Additionally, induction requires significantly less of a footprint than a furnace and it is more energy efficient since only the wire is heated. Finally, induction systems often have lower maintenance costs as there isn't downtime due to required maintenance.
