Why Magneforce Induction Heating
Many applications using induction heating must be set up correctly to provide satisfactory heating results. If the system is not set up properly, heating will be inefficient and ineffective. This may result in poor, inconsistent part quality or the need for a larger more expensive induction power supply.
​
Using our Built In The USA Heat Station induction heaters, over 150 years of combined experience and 1000's of systems sold, Magneforce will design, fabricate, test, videotape and guarantee your heating process. Complete in house heating coil development capability enables us to fine tune and focus the heating . With in house CNC and additive manufacturing capabilities we can provide process fixtures to give you ready to use systems.

How Does Induction Heating Work
An induction power supply converts standard 50/60hz AC power to a high frequency output and delivers this energy to the heating coil.
​
​The heating coil consists of a copper winding custom formed to fit the part and can be made in a wide variety of shapes and sizes. The coil creates and focuses a magnetic field on the part where it's needed to produce the heating required.
A brass shell is dropped into the heating coil, heated to a pre-set temperature and then released into a quench.
Why Use Induction Heating
What Makes An Induction Heating System
What is Induction Heating
Induction heating is a flameless, non-contact, rapid and highly controllable method of heating metal parts using a high frequency electromagnetic field.
When a metal part is inserted into the alternating magnetic field, localized electrical currents will be induced in the part. The resistance of the metal to the flow of these currents causes it to heat up.

Focus The Heat
A basic Magneforce induction heating system consists of an induction heater with matching transformer, a heating coil, and a part or assembly to heat.
​
The heating coil is usually water cooled and custom designed for the application. It can be fabricated in a wide variety of shapes and sizes as required to heat the part.
​
Water cooling, usually in the form of a recirculating coolant system. is required for most systems. Typically, Dynaflux coolant systems are used. Clean, in house water can be used if available.
Operating controls, such as cycle timers, output power control, remote actuators, power control footpedal, thermocouple or infrared temperature controllers may be required, depending on the application. The system shown above is PLC controlled and all operating parameters are entered using the remote touchscreen control..
​Many applications benefit from using process fixtures to hold the part(s) firmly and in the same location to insure even heating for repetitive parts. The fixture must be properly designed to prevent heating and heatsinking of fixture components, reducing heating efficiency and affecting the heating process. Magneforce can supply the fixture or work with the customer for their in house fixture design.

A steel shaft is heated in three locations simultaneously. Carbide inserts will be brazed into each location. The middle position heats a little slower to allow the end carbides to be set in position first.
The shaft to be annealed and the induction heating coil are located inside the enclosure. The coil moves along the shaft to selectively anneal preset locations.

No Charge Induction Heating Evaluation
If you have a project to heat a part or assembly and think induction might be the way to go, contact us and we can help. Our equipment may not be what you need. If it is not suitable we will let you know and tell you why not. It might be the application isn't good for induction or our equipment is not suitable due to frequency or power capability. If it is OK we would be happy to review your application
and discuss it with you. We offer no charge sample testing. We will test heat your part with a custom designed heating coil at no charge and provide you with finished samples, a process report including the model induction heater used, the heating coil, the setup and power and time settings. We can also provide a video of the sample run and thermal imaging when applicable.
