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.

 

HardLine - ndustrial heat treatment systems

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 coils

Having the right coil—and keeping it in the best possible condition—is critical to the efficiency of your induction solution. After all, the coil is the component that actually delivers the heat to the workpiece.

 

Our induction coil services cover all your coil needs: from coil design through to coil manufacture, installation, maintenance, repair and replacement.

 

Coil design

Correct coil design is essential to cost-effective induction heating. This service ensures you get design customized to your heating applications and materials. Which, in turn, means that you get the right heating patterns and your induction heating power supply delivers maximum output. You can use the service when introduction induction heating for the first time, or when upgrading existing coils. 

 

Coil database

Each EFD Induction coil is documented in a database containing all essential information. This makes it quick and easy for us to repair and replace your coils with constant quality. You can use the service when introducing induction heating for the first time, or when upgrading existing coils.

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.
