Induction heating relies on induced electrical currents within the material to produce heat. Used by millions of rice cookers and modern stovetops, it is a method of providing precise, fast and consistent heating for manufacturing applications which involve bonding or changing the properties of metals or other electrically-conductive materials.
An RF power supply converts line power to an alternating current, delivers it to a work coil creating a magnetic field within the coil. Your workpiece is placed in the coil where this field induces eddy currents in the workpiece, generating precise, clean, non-contact heat in the workpiece.
Resonance ensures the most efficient power transfer to your workpiece. Ambrell technology senses and adapts to changes in this point in your configuration. The higher the frequency, the shallower the heating in the workpiece.
Due to hysteresis, magnetic materials are heated more readily than non-magnetic, resisting the alternating magnetic field within the induction coil.
Induced current in the workpiece is most intense on the surface, diminishing below the surface; 80% of the heat produced in the part is produced in the outer layers (skin effect).
The relationship of the current flow in the workpiece and the distance between the workpiece and the coil is key; 'close' coupling increases the flow of current, increasing the amount of heat produced in the workpiece.
The size and shape of the water-cooled copper coil must follow the shape of your workpiece and the variables of your process. The correct heat pattern maximizes the efficiency of heating.
System output determines the relative speed at which the workpiece is heated (e.g., a 5kW system heating a workpiece more quickly than a 3kW system).
We have solutions with output power from 1 to to 800kW
Our Applications Lab Engineers will consider the required temperature change, mass, specific heat and electrical properties of the workpiece, the coupling efficiency of the coil design and thermal losses due to convection, radiation and conduction into your fixturing.
