Brazing faucets with induction heating

Induction for faucets

Manufacturers of high-quality faucets face three tough challenges: how to achieve robust joints; how to achieve virtually invisible joints; how to achieve robust, invisible joints as quickly and cost-effectively as possible.

Little wonder then, that more and more faucet makers are turning to EFD Induction for answers. 

Over the past couple of years, EFD Induction has devised solutions for brazing of faucet tubes to sockets, and for brazing of thread inserts. These solutions are now in use with some of the world’s leading faucet makers. Fast heating times and precise repeatability make induction perfect for faucet brazing. Induction heating is, for example, much faster and more accurate than conventional methods. The fast, consistent heat obtained by induction heating produces full-penetration joints. Induction also reduces the time needed for brazing, while at the same time ensuring perfect-looking individual joints. Variable thermal conductivity means it is essential to balance the heat when brazing thread inserts. Customized induction coils, plus a limitless range of coil positions, achieve the optimal balance. The EFD Induction equipment most commonly used for faucet brazing—the Minac line of mobile converters—features a micro-controller that allows precise output energy control and energy supervision. This micro-controller makes it possible to pre-set programs for faucets of different shapes and sizes. These pre-defined programs, together with coil changes that take only seconds, ensure speedy adjustment times when changing between faucet models.


Induction brazing is cost-effective, too. It consumes less energy than alternative technologies; primarily because with induction, heat is produced only when needed, and is accurately delivered.
