Bonding with induction heating

Bonding with induction heating

Since the early 1980s, EFD Induction has been at the forefront of developing induction bonding solutions. No wonder then that today we are recognized as a leading supplier of solutions to speed up curing processes for bonding in Europe as well as in the Americas.  


We offer full ring bonding and spot bonding. In both cases, the benefits of induction are considerable. The heat is, for example, highly accurate. No problems with excessive temperatures in surrounding areas, which can lead to misshapen components. And it's delivered in seconds, significantly speeding up production and saving energy.  


Our induction bonding solutions are mainly found in the automotive industry, for example for induction bonding of door, hood and trunk panels. Induction is also used for electrotechnical purposes such as bonding of curved strands, break shoes and magnets, as well as within the white goods sector for bonding of guides and rails, shelves and panels.

Induction coils

Having the right coil—and keeping it in the best possible condition—is critical to the efficiency of your induction solution. After all, the coil is the component that actually delivers the heat to the workpiece.


Our induction coil services cover all your coil needs: from coil design through to coil manufacture, installation, maintenance, repair and replacement.


Coil design

Correct coil design is essential to cost-effective induction heating. This service ensures you get design customized to your heating applications and materials. Which, in turn, means that you get the right heating patterns and your induction heating power supply delivers maximum output. You can use the service when introduction induction heating for the first time, or when upgrading existing coils. 


Coil database

Each EFD Induction coil is documented in a database containing all essential information. This makes it quick and easy for us to repair and replace your coils with constant quality. You can use the service when introducing induction heating for the first time, or when upgrading existing coils.

Induction bonding in the automotive industry

Within the automotive industry, induction heating is the primary method of curing or pre-curing adhesives and sealants for closure components such as doors, hoods and trunks. Induction heating is also used to bond parts such as fenders and rear-view mirrors.


Every new car model includes an increasing number of bonded joints, making induction an even more important factor in maintaining high quality and production rates. Also, more and more modern materials are being introduced that require bonding. It’s therefore useful to know that induction heating can now be used to cure adhesives in composites-to-metal and carbon fiber-to carbon fiber joints.


EFD Induction collaborates continuously with automakers and adhesives and sealers suppliers to find new ways to develop the induction bonding process. The EFD Induction Bonding Lab in Detroit is the driving force in this cooperation. It is the only bonding lab in the induction industry and provides excellent simulations of real-world bonding.
