EFD Induction aims to be in the driver's seat when it comes to electrification of the automotive industry. Our newest film shows just how much induction technology can contribute to a future of carbon-free driving.
Induction preheating is a process where materials or workpieces are heated by induction prior to further processing. The reasons for preheating vary. In the cable and wire industry, cable cores are preheated before insulation extrusion. Steels strips are preheated prior to pickling and zinc coating. Induction preheating also softens metals before bending, and prepares tubes and pipes for welding. Mobile preheating solutions facilitate onsite repairs of bearing assemblies.
EFD Induction preheating systems are extremely efficient, resulting in major energy savings. When preheating steel strips and cable and wire, diode rectifiers ensure a constant power factor of 0.95, thus eliminating reactive power costs. Cycle times are short, and continuous automatic matching means a single coil can handle wide production ranges. Induction preheating systems are compact and easy to integrate into existing or planned production lines.
Induction preheating is employed in the automotive, mechanical, aeronautical, electrotechnical, white goods and shipbuilding industries. A major area of use is preheating for welding. Our mobile Minac systems are used in the offshore sector for onsite weld preheating. Minac units are also frequently flown to oil platforms and airports to perform repairs and maintenance.
A heating solution based on EFD Induction’s Minac induction heating system has succeeded in improving output for Blue Wave, one of the world’s largest manufacturers of rigging hardware for the marine, architectural and industrial markets.
The Tampen Link project in the North Sea underlines the amazing versatility of induction heating. In this case, EFD Induction expertise is helping weld a branch pipe onto a 20’’ main high-pressure gas pipe located 145 m below the surface of the North Sea… without any interruption in the flow of gas!
EFD Induction is proud to present the New Generation Sinac with a fully digital control system that is prepared for Industry 4.0. Predictive data and insights will enable reduced use of energy and lower operation costs allowing for a sustainable and profitable production.
The automotive industry is going through a paradigm shift. New powertrains and materials drive the change towards products designed for a circular economy. As induction heating is far more energy-efficient and eco-friendly than other heating alternatives, the technology is growing in importance.
