Induction heating automotive parts


For years, EFD Induction has been a trusted supplier of induction heating solutions to numerous automakers around the world. We also work with many tier-one suppliers and sub-contractors.

Induction heating is used within a variety of fields in the automotive industry.
For example: 

Induction hardening

  • engine parts such as valves, crankshafts, camshafts, connection rods and starter rings
  • transmission parts, for example CV joints, tulips and axle shafts
  • suspension parts such as shock absorber rods, springs and suspension arms
  • parts for automatic and manual gear gearboxes, for example rings, selector shafts and sun gears
  • clutch springs and brake pads

Induction tempering

  • camshafts, crankshafts, drive shafts, torsion bars, couplings, rocker arms, rock drills, chains, suspension arms, clutches, brake discs, steering wheels, CV joints, tulips, shock absorbers, inner and outer races, control rods, valves and output shafts.

Induction brazing

  • aluminum parts for air-conditioning systems, for example evaporator and condenser connections (tube-to-tube, tube-to-block, tube-to-tank)
  • steel and copper components, e.g., brake linings, fuel injection pipes
  • short-circuit rings for electric motors

Induction bonding

  • magnets in electric motors 
  • doors, hoods and trunks
  • fenders and rear-view mirrors

Induction pre-heating

  • transmission parts, for example shrink fitting of gear wheels 

Induction postheating

  • engine parts and brake discs (polymerization) 

Induction straightening

  • steel chassis
  • truck making and repair


Induction hardening. What makes it so effective?

Learn about the potential and benefits of induction hardening.

Aluminium brazing

Brazing aluminium is a demanding task. The reason is the need for exact temperatures. EFD Induction has unrivalled expertise in this application and is the world's leading developer of induction heating solutions for aluminium brazing.
