Tempering with induction heating

Tempering with induction heating

Tempering solutions from EFD Induction are present in the automotive and automotive-supply industries. In fact, tempering can be performed on all hardened components—bars, joints, shafts, etc.

 

Tempering a component only takes around ten seconds, unlike in a furnace where it can take a couple of hours. The reason is that induction generates heat directly in the material— exactly where you need it.

 

This means tempering can be directly integrated into your production line to improve throughput, increase flexibility and save floor space.

 

Industrial heat processing equipment

HardLine

Industrial heat treatment systems

 

HardLine is our range of stationary heat treatment systems for surface- and through-hardening. 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 day out, year after year.

 

The HardLine family includes vertical, horizontal centerless and customized machines—and serial and/or parallel compensated induction power sources with a wide range of output power and frequencies.

Induction tempering

Induction tempering in the automotive industry

For years, induction tempering was taboo among potential users. But technical development spearheaded by EFD Induction—and real-life validation in the automotive industry—have resulted in induction tempering now being a must for a wide range of components.

 

A vast amount of parts can be treated with induction tempering such as 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.

 

Fast, accurate and flexible, induction tempering replaces the huge wasteful furnaces used for decades in heat treatment shops. Fatigue tests have confirmed the quality results delivered by our induction solutions.
