EFD Induction The process, the products and the people. And how they are boosting industrial productivity. in amazing ways.

Putting the smarter heat to smarter use. What this brochure is about. Meet the family. An overview of EFD Induction products. Faster. Better. Cheaper. A survey of three key benefits of induction heating. 907.5°C in 3.4 seconds. Time and again. And again. How induction heating works—and how it is superior to alternative technologies. In the heat business, the hardest part can be to stay cool. An introduction to EFD Induction services—what they are and how you benefit. “I’ll drive over right away.” EFD Induction in the real world—a case story from our files. A passion for heat. The EFD...

Putting the smarter heat to smarter use. Welcome to EFD Induction. In the following pages you’ll read how induction heating is superior to alternative heating technologies. You’ll read how induction heating, because it’s faster than these alternatives, increases throughput. You’ll read how induction heating improves—and maintains—the quality of whatever it is you make, mend or process. And you’ll read how induction heating achieves the above while at the same time cutting costs. Just as important, you’ll read that we lead the world in finding new, exciting applications for induction...

Faster. Better. Cheaper. The technical features of induction heating deliver three key benefits: improved throughput, better and consistent quality, reduced costs. Throughput Integrating induction heating into the production line improves production efficiency. You cut lead times, and speed up throughput. The heating process itself is faster than with open-flame and oven alternatives. Accurate repeatability means you get to be faster because you get it right the first time. Quality Quality improves because you can apply pre-set temperatures to pre-set parts of individual workpieces. And...

FA S T E R – T H R O U G H P U T Ease of integration into production line Ramp-up time BETTER – QUALITY Heat pattern control Temperature level accuracy Ramp-up time control Dwell-time accuracy Repeatability CHEAPER – COST Yield Energy The scores used in this table are approximations only, designed as a general guide. The performance rating of the three heating methods can vary from case to case, depending on the application involved, workpiece characteristics, operator skills, etc.

907.5°C in 3.4 seconds. Time and again. And again. Induction heating has numerous advantages over alternative technologies: Quick The produced heat from a frequency converter is instant. It takes less than one second to achieve a uniform surface temperature of 1,000°C on small metal components. Accurate Just the right temperature is delivered, just where it’s needed to individual workpieces. And because of the range of frequencies available, to just the right depth. Heat distribution is precise, too. We can customize induction coils to suit practically any shape or size of workpiece....

Some amazing facts about induction heating. • An EFD Induction frequency converter with an output power of 100 kW can harden a 60 mm diameter shaft to a depth of 2 mm (800°C at 2 mm) with a feeding speed of 1 m per minute. • Using one of our mobile converters, you can heat 1 kg of steel from 20°C to 800°C in five seconds flat. That’s a speed-of-temperature increase of 160°C per second. • Induction heating is ten times more efficient than conventional ovens at curing the adhesives in automobile hoods. To cure one hood normally requires 220 kWs. As induction heating uses 340 kWs from the...

Apart from our superior applications knowledge, equipment technology, coils capability, materials know-how and local presence, we’re pretty much like any other induction heating company. What makes EFD Induction special? Applications knowledge To date, EFD Induction has more than 9,500 installations in 75 countries. A large number are customized heating solutions—unique installations for specific production needs. This experience has given us unrivaled knowledge of applications as diverse as annealing, bonding, brazing, curing, forging, shrink-fitting, hardening, straightening, tempering,...

The differences are obvious. What about the similarities? A can of peaches, a cruise liner’s hull, a tub of yogurt, power station turbines, cables under the ground, pipelines under the waves, and countless trains, planes and automobiles. What unites these different products is that induction heating is used to make them, maintain them, repair them and recycle them. (In case the yogurt tub intrigues you, induction heating attaches the foil lid to the plastic container. As for canned peaches, induction heating helps coat the tin on the can’s inside so that conserved foods remain untainted.)...
