Electromagnetic forming is a fast metallic working process that shapes metals inside a strong magnetic field without contacting the metals, generally applicable to lightweight and thin metals.

Key Features:

Process Mechanism: The rapidly decaying magnetic field creates eddy currents in the metal workpiece and an opposing force on the metal, which forms against the die or the mold.

Non-contacting Process: Eliminates tool wear and minimizes surface damage.

Materials Suitable: Conductive metals such as aluminum, copper, and brass have been the most common materials subjected to this process.

Electromagnetic Forming finds extensive applications in automotive, aerospace, and electronics industries, where it is used for the manufacture of lightweight components with high precision. It is well suited to joining dissimilar materials, shaping tubular components, and forming of complex geometries without compromising material strength. Research is underway to broaden its current applications, enhance energy efficiency, and improve process control, making it truly a key technology for present metalworking.
