Magnetic induction allows energy to be transferred safely and efficiently from a coil to any ferromagnetic material; the energy transferred to the target is transformed into heat, directly generated in the metal itself.
This allows to maximize the heating performance compared to any other method, thus avoiding energy waste.
Inductive molds preheating: no more open flames inside plant
A safe mold heating method for metal forming
Metal forming is an ever-changing world, with innovations in materials and alloys that lead to new requirements in production processes. However, molds preheating is often still carried out with obsolete and unsafe techniques. Atos Induction, a specialist in induction heating, overcomes this limitation by offering a patented system for inductive mold heat methods.

Traditional mold heating methods
Molds preheating require continuous supervision of specialised personnel and they have several safety disadvantages:
- Induction furnaces require the risky handling of heavy & hot molds from the furnaces. Besides, induction furnaces are bulky and very expensive
- Open flame burners present enormous dangers related to the use of combustible gases in indoor environments and it doesn’t allow an uniform mold heating

Inductive technology in molds preheating
Atos Induction has exploited the benefits of magnetic induction to create a patented innovative induction heating method dedicated to metal forming.
The induction molds preheating system consists of a flat coil, powered by a control system which manages the heating process.

This solution overcomes all the disadvantages of traditional heating methods, through the safe use of induction heating blankets:
- Reduced heating time, thanks to the absence of thermal inertia on heating transfer
- Energy saving because of intrinsic induction high efficiency
- Maximum heating uniformity achieved by generating heat directly inside the material
- Automatic timed or thermoregulated mold heating control, without the need of operator supervision
- Easy to use, no specific skills requested by the user. Simply place the blanket in contact with the surface of the mold and start heating
- Maximum safety during heating operations, eliminating the use of combustible gases and open flames
