Induction Heat Treatment is a very fast and extremely precise method for heating of metal compositions. Temperature increase speed can be controlled accurately and in contrast to traditional heat treatment technologies (heat belts, gas/open flame), the heat is generated inside the metal - not just at the surface, but in-depth

The technology is highly suitable for:

• Annealing (stress relieving heat treatment)
• Hardening (surface as well as in-depth)
• Controlled temperature increase / decrease
• Pre-heating and temperature stabilisation for certificate welding
• Shrink-fitting and dis-assembly of shrink fitted components

And it can be used for

• Heat-treatment of crank- and camshafts
• Heat-treatment of valve seats and piston crowns
• Heat-treatment of new and  damaged components for certificate welding
• Surface hardening / in-depth hardning
• Dis-/reassembly of e.g. camshaft parts 

Advantages include: 

• Accurate in-depth temperature control (+/- 3°C for small and large items) controlled by touch-panel PLC
• Multiple point temperature monitoring using thermocouples
• Much faster than traditional solutions due to high and effective in-depth energy transfer (up to 40 kW effect), without unnecessary stressing of the material.
• In-depth heat transfer eliminates the formation of micro-cracks, even at steep temperature profiles
• Possible to follow pre-programmed heating / cool-down curves
• No surface damages due to excessive heat treatment, unlike the use traditional methods like heat belts or gas
• Possible to work on heated item while equipment maintains temperature / follows temperature profile.
• No unnecessary heat loss to surroundings means better working environment
• Maintain temperature during welding/machining/other processing of heated item
• Document that the heat treatment process conforms with standards and norms
• No need for manual monitoring of heat process - use personnel for other tasks during heat treatment
• Fixed or ultra-flexible coils - up to 45 m of coil possible
• Induction Unit ready immediately after powered on
• Flexible heat transfer layout ensures possiblity to compensate for heat loss
• Multipurpose - one unit can be used for more than one application
• Mobile or stationary setups, robust and with a small footprint.
