What is induction bonding?

Induction bonding uses induction heating to cure bonding adhesives. Induction is the main method for curing adhesives and sealants for car components such as doors, hoods, fenders, rearview mirrors and magnets. Induction also cures the adhesives in composite-to-metal and carbon fiber-to-carbon fiber joints. There are two main types of automotive bonding: spot-bonding, which heats small segments of the materials to be joined; and full-ring bonding, which heats complete joints.

What are the benefits?

  • Precise energy inputs for each panel with spot bonding systems
  • Small heat affected zones minimise total panel elongation
  • Little need for spare coils with a one-size-fits-all coil for full-ring bonding
  • Clamping is not needed when bonding steel panels, which reduces stresses and distortion

Where is it used?

Induction is the preferred bonding method in the automotive industry. Widely used to bond steel and aluminium sheet metal, induction is increasingly employed to bond new lightweight composite and carbon fiber materials. Induction is used to bond curved strands, brake shoes and magnets in the electrotechnical industry. It is also used for guides, rails, shelves and panels in the white goods sector.
