Induction hardening systems for every hardening job

 

  • For simple and complex geometries: HardLine includes vertical, horizontal centerless, rotary table, crankshaft and customized machines.
  • Comprehensive range: From small, manually loaded machines to large, automatic turnkey hardening plants complete with component handling, washing, straightening and tempering capabilities.
  • Versatile: Hardens gears, camshafts, drive shafts, crankshafts, torsion bars, couplings, rocker arms, rock drills, chains, suspension arms, clutches, brake discs, steering racks, CV joints, tulips, shock absorbers, inner and outer races, control rods, valves and output shafts.
  • Optimum results: At the heart of each HardLine machine is an EFD Induction Sinac heat generator, the industry’s most advanced induction frequency converter. These acclaimed converters help ensure optimum hardening results—day in and day out, year after year.
  • In-line integration: Includes a full range of hardening systems for in-line integration—which results in shorter lead-times. This key benefit is enhanced by minimal foot-prints, easy installation, user-friendly controls and clever design features for quick and easy set-up, changeovers, cleaning and maintenance.
  • High availability:  Choosing HardLine means choosing proven mechanical solutions and high availability. Modular sub-assemblies, along with the use of modules from proven suppliers, further ensure the reliability of our solutions.
  • Latest technical features: Your HardLine solution incorporates the very latest in induction science—ensuring you get the most efficient and reliable systems available.
  • Spares, services and training: With manufacturing plants, parts distribution systems and representatives in Asia, Europe and the Americas, EFD Induction can offer customized preventive maintenance programs as well as training programs, so your operators can make the most of your HardLine system.
