INDUTI is a Portuguese company established in Castelo Branco specialized on induction technology for all kinds of industry. Its main proposal is to guide its clients in voyage to the present where induction technology can serve to boost productivity by optimizing resources and making the process more efficient. Although induction heating is now a mature process technique that offers many advantages to your production, there are some specific details you should consider before selecting the right system for your application. INDUTI gives you the ultimate technology solution and guides you through all the process from the conceptualization to the equipment on your shop floor.
INDUTI was born in 2017 and is since 2019 a business partner of the also Portuguese MECALBI, a worldwide company that operates mostly in the automotive industry offering innovative solutions for the wire harness business. Since 2006, our partner has been transforming and the way this industry uses heating solutions and it is INDUTI intent to take advantage of that know-how and continue in that path using different kind of technology and offering different kind of solutions, but with the same objective in mind: to revolutionize induction technology!
Induction heating process is like a kind of magic!
We put a metal part inside a coil connected to an electric current and that is when magic happens! Suddenly, with the speed of an impulse, an invisible and mysterious force turns the metal grey into an incandescent orange surface. We can imagine how Michael Faraday felt almost 200 years ago when he discovered the principles of electromagnetic induction that would transform the future of many industries. The metal industry would become, moreover, one of the most benefited from this technology, through the multiple applications that can be obtained, such as fusion, welding, conformation, among others. Although it may seem like magic, the principles of induction heating are very simple to understand.
But what is exactly induction heating and how does it work?
First statement: Induction heating is the most clean, efficient, cost-effective, precise, and repeatable method of material heating available to the industry today (we took this from Wikipedia… It doesn’t lie!) In short: we just need an electric power generator, a controller machine and an accurate coil design! So, when an alternate electrical current is passed through the copper coil, a magnetic field is created around it. If a steel bar is inserted into the coil, a magnetic flux is generated, which creates heat within the immediate surface of the inserted bar. The depth of the heated surface will be dependent of some variables like induction power and frequency, residence time within the coil or carbon content of the steel bar, when applied. However, there’s a general rule we may consider: the higher the frequency, the shallower the heating of the part.
