Seam normalizing and full body annealing

 

EFD Induction offers seam annealing of tube welds and full body annealing of both magnetic and non-magnetic tube products. We also provide integrated induction annealing solutions for steel strip and wire production.

 

Induction annealing has many benefits. The heat is generated directly in the material, leading to high efficiency and low energy costs. It is also a fast and controllable process, which will improve your throughput. And the heat is very accurate—crucial to meet today's stringent quality standards.

 

The right heat in the right place reforms the material structure and reduces internal stresses in just the way you want.

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.  

Brazing with induction heating

 

EFD Induction offers brazing in various important fields such as the automotive, aviation, electrotechnical and white goods industries. It includes brazing of aluminum, brass, copper, copper alloys, iron and cast iron, steel and stainless steel.

 

There are many reasons why using induction heating instead of gas for brazing is clearly beneficial. Induction transfers more energy per square meter than an open flame, resulting in faster heating cycles—put simply, you produce more components per hour.

 

The heat is also easy to check and adjust. You reduce the risk of overheating, which can lead to higher porosity and weaker joints. What's more, you reduce the risk of cold brazing as induction generates the heat in the base material.

Just as important, induction heating improves the working environment and safety. No gas needed, no open flame, no additional heating.

Induction postheating

Postheating with induction

Postheating is a major area for EFD Induction, and we have designed and installed numerous solutions around the world. Many of our postheating solutions are concentrated to the automotive, aviation, cable and wire, electrotechnical, and tube and pipe industries.    

 

Induction is an excellent way of postheating. The heat is generated directly in the material and is very accurate—time and time again. This reduces radiation loss and shortens heating times compared with gas or furnace.   Even more important is the higher quality and throughput achieved in the end. You get, for example, a faster and improved cross linking process of cable insulation.

Induction preheating

Preheating with induction

EFD Induction is present in a series of industries for preheating—primarily the automotive, cable and wire, electrotechnical, and tube and pipe industries. In many cases, our preheating solutions are integrated into production lines.

 

Using induction rather than gas or a furnace for preheating has several advantages. Heat transfer is direct—minimizing heat loss and energy consumption while increasing the production rate and improving quality.

 

The heat can also be controlled precisely. This makes it possible to reduce the temperature when welding and then achieve a lower cooling rate. Less risk of cold cracking and excessive hardening are some of the benefits.

 

And you can forget heat-spreading flames. You get a better working environment, less need for cooling and a lower fire risk.

 

Straightening with induction heating


Our deck and bulkhead straightening solutions are found in the ship- building industry (deck straightening), construction industry (straightening of bridges) and trains/trucks industry (production and repair of locomotives, rolling stock and Heavy Goods Vehicles).  

 

Using induction for straightening means that you get the right heat, exactly where you want it. When repairing a steel chassis on a truck, for example, there’s no need to dismount heat-sensitive components such as brakes and cables.   Induction also makes life easier for staff and the environment. No gas flame to emit dangerous fumes. No flame to burn the skin. And, in addition, induction heating is easy to learn and safe to use.

Induction heating of aviation parts

Induction heating for the aviation industry

Product quality and process consistency are obviously crucial to the aviation industry. That's why the accurate, repeatable and contact-free heat of induction heating has become so popular with aircraft manufacturers, airlines and their suppliers.

 

Our compact multipurpose Minac converters, for instance, are particularly sought after by maintenance divisions because of their flexibility and ease of mobility.

 

Here are some typical uses of our equipment within the aviation industry:

Induction heating for the cable and wire industry

The unrivalled accuracy, control and efficiency of induction heating makes it ideal for many key tasks in the manufacture and processing of wire and cable products.

 

EFD Induction offers solutions for many applications from structural ferrous and non-ferrous wires, copper and aluminium cable and conductors to fibre optic production. The applications are very wide ranging including, but not limited to, forming, forging, heat treatment, galvanizing, coating, drawing etc. at temperatures from 10’s of degrees to in excess of 1,500 degrees. Developing systems that are optimised for your requirement with customised solutions is an EFD Induction speciality.  


The systems can be employed as your total heating solution or as a booster to improve the productivity of an existing furnace by acting as a pre heater. Our induction heating solutions are renowned for their compactness, productivity and efficiency.
