Overview
Curing adhesives on car panels
ENRX induction bonding systems use controlled induction heating to cure bonding adhesives and sealers for automotive components such as doors, hoods, fenders, tailgates, bumpers and battery modules. Induction bonding is the primary method used in the automotive industry due to its high throughput, excellent process control and compatibility with advanced materials including aluminium, steel, carbon-fiber composites and EV battery structures.
Two bonding methods are supported: spot-bonding using the U-coil, which heats localized areas with minimal distortion, and full-ring bonding using an adjustable two-turn flexible coil that ensures uniform heating around the entire joint. Temperature is rapidly ramped and then stabilized to meet adhesive curing profiles. Energy supervision circuits ensure consistent quality and detect deviations in coil placement or panel positioning.
