Induction Heating Solutions

Induction heating is a modern and efficient method used for heating materials, primarily metals, through electromagnetic induction. It is widely applied in industrial processes such as hardening, brazing, metal melting, and surface treatment due to its precision, speed, and energy efficiency.

Induction heating machines are used because they offer efficiency, fast heating, safety, cleanness, and accurate control. They are the fastest method for hardening and heat treating, resulting in minimal distortion and a fine-grain microstructure. Induction heating is accurate, fast, repeatable, and efficient, making it suitable for precise or repetitive operations. It is a rapid, energy-efficient, flameless method of heating electrically conductive materials.

High efficiency and energy saving.  It can save 2/3 of the power than the high frequency of the electron tube.

Low maintenance costs. No fragile and expensive tubes.

Special Safety: No high voltage, eliminating the danger of high voltage electric shock.

Easy to Install: Just connect the power supply and water pipes; it can be completed in 10 minutes.

Easy operation: user can learn in a few minutes.

For different workpiece materials, sizes and shapes, the frequency will be different accordingly.

If you work with glass or ceramics, a compact vacuum furnace is a great solution for brazing. You’ll get quick, clean heat with very precise temperature control.

A typical induction heating system consists of the induction heating power supply, an induction heating coil, and a water-cooling source, which cools the coil and several internal components inside the power supply. The induction heating power supply sends alternating current through the induction coil, thus generating a magnetic field. When a work piece is placed within the coil and enters the magnetic field, eddy currents are induced within the workpiece, generating precise and localized heat without any physical contact between the induction coil and the work piece.

The varying magnetic field required for induction heating is developed in the induction heating coil via the flow of AC (alternating current) in the coil. The coil can be made in many shapes and sizes to custom fit a specific application. The coils can range from tiny coils made of copper tubing used for precise heating of extremely small parts in applications such as soldering and ferrule heating to large coil assemblies of copper tubing used in applications such as strip metal heating and pipe heating.

Not likely. Induction heating is a very effective, efficient means of heating. Most of our customers who are switching to induction for the first time see their utility bills go down.

Our team of metallurgical and mechanical engineers will be glad to have a look at your parts and process and give you our best advice – no obligation!

The induction coil design is one of the most important aspects of an induction heating system. The coil is a custom design to give your work piece or part the proper heating pattern, maximize efficiency of the induction heating power supply’s load matching system, and to accomplish these tasks while still permitting ease of loading and unloading your part.

Induction heating can benefit your process in a number of ways. Induction heating is highly repetitive once initial adjustments are made to the power supply. Following this phase, part after part can be heated with identical results so long as the parts are introduced to the coil similarly each cycle. This can also lead to better material utilization and product yield. Induction heating can reduce or eliminate the need for skilled operators in application such as brazing and soldering. The ability of induction heating to heat all parts identically lends itself to automation of the process. Induction heating can also heat the part in a highly localized fashion, which can be extremely beneficial when it is desirable or necessary to limit the heat to only a certain region of the part.

In addition to some of the points mentioned in the previous FAQ, induction heating is also a clean form of heating which does not emit unpleasant odor or heat. Because the current is induced directly into the part being heated, there is no radiant heating effect into a facilities ambient environment. The location of the desired heat zone can be defined to a specific area on a workpiece in order to achieve accurate and consistent results. Induction heating equipment is instantly on which means it requires no warm-up time as other conventional heating sources do. Induction heating systems are extremely energy efficient.

The induction coil is cool to the touch; the heat that builds up in the coil is constantly cooled with circulating water.

Yes you can, but the nitrogen has to be clean and have a low dew point.

Sure, in fact induction heating is preferable for diamonds bits because it works so quickly. The longer the diamond remains at heating temperature, the faster it degrades. We recommend atmospheric brazing in a vacuum atmosphere for the best results.

Yeah, we get that question a lot. It depends on the geometry of your part and how you want to heat it. If you have a part with simple geometry and your process calls for heating a specific area of the part, direct induction heating will generally be preferable. However, if you need to heat the entire part, or if the part has a complex shape, then you’ll achieve better results with an induction heating vacuum furnace.

Yes, with a vacuum system. We’ve had some success in with foil preforms, but we’ve had no luck with nickel paste because the binder in the paste doesn’t flow. So we suggest using a high vacuum system because it will work faster than oven heating and there is no time for nitrides to form.
