2005 - EFD Induction

Peak performance from Minac

EFD Induction prides itself on being a pioneer in finding new, exciting applications for induction heating. A textbook example is the recent delivery by EFD Induction France of a Minac 6 Twin to SNR (Société Nouvelle de Roulements), one of the world’s leading bearing manufacturers.

EFD Induction solves bolt heating challenges

Induction heating is rightly prized for its versatility. But bolt heating? Is induction really an effective alternativeto traditional gas and resistance heating methods? Here we report on how two customers fared when they turned to EFD Induction to solve their bolt heating challenges.

Preheating of turbine
The EFD Induction technician were rushed to the platform to heat and remove the turbine’s thrust collar, auxiliary gear and coupling hub from the turbine rotor.

On-site upgrade to single-cabinet welder
EFD Induction Inc. and Century Rollforming Incorporated (CRI) of Norton Shores, Michigan, team up to create a perfect solution for the welded, rollformed shape industry. The Weldac took center stage.

Induction heat straightening

Induction hardening of heavy-duty hydraulic motors
A new EFD Induction solution has helped Hägglunds Drives slash hardening cycle times by 85% for large cam rings, and 45% for smaller rings.

Single-cabinet welders with patented IGBT solutions
In October last year, EFD Induction supplied an 1800 kW Weldac to SAFA in Iran. During the factory acceptance test, the unit was tested at 1918 kW/100 kHz into calorimetric load.

Welding copper and steel together with induction
EFD Induction’s Minac induction heating equipment and services save the production process of Norwegian customer NLI A/S, and provide a rapid return on investment.

Induction brazing and soldering the inlet caps and outlet pipes of fuel tanks
EFD Induction India has improved the soldering application with units recently supplied to the TVS Motor company.

Induction heating of flat-strip steel springs
Autoliv Spring Dynamics, an automotive parts manufacturer based in the UK, demands quality and reliability throughout their operation. And it has to—because the company makes the flat-strip steel springs that retract car safety belts.

How to get the most out of your induction coils
Kristian Berggren of EFD Induction has some simple tips on how to boost the productivity—and lifetime—of your induction coils.

Leading suppliers of induction heating equipment in China
In 2002, EFD Induction chose Shanghai as the location of its first Chinese factory. In just three years EFD Induction has developed to become one of the leading suppliers of induction heating equipment in China.

Induction heating of wind power generators
The performance levels of the Minac generators are well-documented, but in Spain that performance is reaching new heights – quite literally!

Induction hardening of camshafts and crankshafts
Caterpillar, Komatsu, JCB, John Deere, Poclain, Clark—they all have two things in common. One, they make large, heavy machines whose case depth, part dimensions and production rates differ radically from those in the automotive industry. Two, they are all customers of EFD Induction, and use the most innovative machines and production solutions available.

In-line heat treatment
Kristian Berggren of EFD Induction Sweden discusses some of the factors that make in-line heat treatment an attractive option.

Part-heating of roofing pliers with induction
We explain how precise induction heating is helping a customer part-heat special roofing pliers.

Induction straightening of welded deck
Most landlubbers don’t know it, but the straightening of welded deck and bulkhead plates is a crucial task in modern shipbuilding. It’s also a task that EFD Induction has been making easier and more cost-efficient for the past quarter of a century.

Induction spot-bonding
As one of the world’s most quality-conscious carmakers, few are as choosy about their partners as Jaguar. So EFD Induction UK is particularly proud to report on their ongoing collaboration with the legendary auto marque.

Die hardening with induction
It’s a well-known fact that all dies used in the automotive industry have to be hardened. It’s also well known that traditional gas heating is slow, difficult and inefficient. But there is another way. Alessandro Mariani of EFD Induction Italy discusses the technology—and the benefits—of induction hardening. Surface hardening of dies is essential, not only when producing new dies, but also following repair welding. However, traditional hardening methods—which use gas flames as the heat source—are notoriously slow, costly and difficult.

Induction heating of wind power turbines
EFD Induction Spain already supplies induction solutions to many of the Iberian Peninsula’s leading automotive, electrical and engineering companies.

Simulate the heat stresses with induction
EFD Induction prides itself on being a pioneer in finding new, exciting applications for induction heating. A textbook example is the recent delivery by EFD Induction France of a Minac 6 Twin to SNR (Société Nouvelle de Roulements), one of the world’s leading bearing manufacturers.
