What is induction tempering?
Induction tempering is a heating process that optimizesย mechanical properties such as toughness and ductility
in workpieces that have already been hardened.
What are the benefits?
The main advantage of induction over furnace temperingย is speed. Induction can temper workpieces inย minutes, sometimes even seconds. Furnaces typicallyย take hours. And as induction tempering is perfect forย inline integration, it minimizes the number of componentsย in process. Induction tempering facilitates qualityย control of individual workpieces. Integrated inductionย temper stations also save valuable floor space.
Where is it used?
Induction tempering is widely employed in the automotiveย industry to temper surface-hardened componentsย such as shafts, bars and joints. The process is alsoย used in the tube and pipe industry to temper throughhardenedย workpieces. Induction tempering is sometimesย performed in the hardening station, sometimesย in one or several separate temper stations.
What equipment is available?
Complete HardLine systems are ideal for many temperingย applications. The chief benefit of such systemsย is that hardening and tempering are performed byย one machine. This delivers significant time and costย savings in a small footprint compared to alternativeย technologies. With furnaces, for example, one furnaceย often first hardens the workpieces, with a separate furnace
then being used for tempering. Solid stateย DAWEIย Induction Heatingย Systems are also used forย tempering applications.
