At Induction Innovations, we proudly design and produce advanced induction heating tools, including a variety of induction heating coils tailored to assist in the removal of stuck parts, auto glass, moldings, bedliners, and other applications.

The induction heating coils play a pivotal role in the heating process, transferring warmth from our Mini-Ductor® tools to the components being treated. These coils are essential for loosening rusted or seized hardware, effectively working against corrosion and thread-lock compounds.

For those who have acquired a Mini-Ductor tool, you'll find that every kit is supplied with a starter set of coils. If you're unfamiliar with the induction heating process, feel free to explore our applications page or reach out to an induction heating specialist who can guide you in selecting the most suitable coil for your needs.

Understanding Induction Heating Coils

Induction heating coils are key accessories for our induction heating systems, which generate electromagnetic waves to heat and expand ferrous materials. These coils are inserted into each unit and strategically wrapped around the corroded or stuck item, ideally without direct contact.

The potential applications are vast, aiming to release ferrous metal components that are immovable. Moreover, our induction heating tools can effectively aid in detaching components from vehicles, including windshields and adhered graphics, by applying heat to the metal substrate and weakening adhesive bonds.

The induction heating technique provides a precise, safe, and dependable method for removing rusted or corroded parts. Utilizing induction heating prevents collateral damage and mitigates risks that can stem from traditional heating methods.

Since the coils are integral to the induction heating method, we urge users to adhere to proper usage practices. Below, you will discover our guidelines for optimal coil usage, selection tips, distinctions among various types, and maintenance advice to ensure maximum effectiveness.

Varieties and Sizes of Coils

Pre-Formed Coils

Induction Innovations provides a selection of over 30 uniquely sized coils to cater to diverse requirements. The majority of our coils are pre-formed, meaning they are molded into specific sizes and shapes. These coils maintain their form throughout their lifecycle, but altering the leads to accommodate inline applications is possible without compromising their integrity.

Bearing Buddy® Flexible Coil

The Bearing Buddy is a flexible coil designed to wrap around inline applications or objects that cannot be accessed with standard pre-formed coils. While the Bearing Buddy wire is quite flexible and won’t retain shape, it remains equally effective as our pre-formed coils.

We offer the Bearing Buddy in two sizes, 96' and 41'. Additionally, we provide a coil pack that includes both sizes and features a heat-resistant mat. This mat prolongs coil lifespan by shielding the insulation from wear and tear caused by direct contact with heated metal.

Our company stands as the premier electromagnetic induction heater provider. We are committed to fulfilling all your needs with expertise. Our knowledgeable staff is ready to assist you in finding the right product.

For optimal outcomes, wrap the mat around the object and then coil the wire 3-4 times to enhance the magnetic field strength. Increased wraps translate to improved results.

U-Form Coil

The 23' U-form coil offers versatility, allowing you to shape it to fit any required size! Like the pre-formed coils, the U-form coil retains its shape.

To craft a coil, select a socket that matches the size of the bolt you intend to extract and wrap the U-form coil around it. For peak performance, ensure to wrap the coil 3-4 times around the object.

Three Key Steps for Effective Induction Heating Coil Usage

Step 1: Choose the appropriate size coil for your application.

The induction heating coil must fit snugly around the target application, leaving a small gap between the coil and heated object. A tighter fit (without contact) enhances the heating efficiency.

If the coil diameter is too large, heating may take longer. Conversely, a coil that is too small risks damaging insulation and prematurely wearing out.

Step 2:Secure the coil correctly.

Use the twist-lock function on the Mini-Ductor Venom® and Venom HP, or employ the thumb screws when utilizing the Mini-Ductor II.

Note: Ensure both thumb screws are tightened concurrently to secure the coil properly.

Refer to our coil guide for a detailed step-by-step procedure.

Step 3: Heat for 5-20 seconds and verify if the application has loosened.

Continue the process if the application remains bound until it can be easily loosened. These brief heat cycles help safeguard both the tool and coils. Most often, there is no need for the application to reach red-hot temperatures, as demonstrated in our videos and live demonstrations. We heat bolts to red-hot mainly to illustrate the precise and safe heating capabilities of our tools, along with the speed at which ferrous metals can be heated.

Identifying Normal Wear and Tear vs. Damage

Following the initial use, you might observe some browning or darkening of the coil's insulation; this is a standard occurrence that persists with regular usage. With appropriate handling, a single coil can endure from'200-300 applications.

Should your coils show signs of insulation loss or fraying, it is vital to replace them immediately!

Using compromised induction heating coils is extremely hazardous. Heating metal on metal can lead to arcing, resulting in burnout of the unit. Furthermore, arcing can generate sparks, posing a potential fire risk.

Coil Replacement Options

We provide a range of replacement coils in various sizes, available for individual purchase or within our coil kits. We do not offer replacement insulation for coils and advise complete coil replacement if the insulation sustains damage. Purchase our coils conveniently through our online store or at your local tool supplier.
