Coating & Adhesive Curing with Induction Heating

Fast, Clean, and Controlled Heat for Paint, Powder, and Structural Adhesive Curing

Induction heating provides a highly efficient and localized method for coating curing and adhesive activation, offering precise thermal control with rapid heat-up — ideal for paint drying, powder coating, epoxy bonding, or glue line curing.

Whether applied to electric motor housings, automotive body parts, or steel structural components, induction delivers reliable results with reduced cycle times and superior energy efficiency compared to ovens or IR lamps.

Why Induction for Coating & Adhesive Curing?

· Instant Heat at the Point of Application — No warm-up time, no ambient energy loss

· Localized, Controlled Heating — Heats only the coated or bonded zone

· Clean and Contactless — No contamination, open flames, or air turbulence

· Fast Process Cycles — Greatly reduces overall production time

· Perfect for Automation — Easily integrated with robotic arms or conveyor lines

Typical Applications

· Electric Motors: Curing protective paint on stators and housings

· Automotive Components: Bonding door frames, hoods, brackets with structural adhesive

· Steel Structures: Powder coating of beams, brackets, fasteners

· Consumer Appliances: Surface finish curing on metal panels

· Adhesive Activation: Two-part epoxy or thermosetting glue curing in seconds

· Preheat for Coating: Raising part temperature before paint or powder application
