Comparison With Mechanical Forming
Electromagnetic forming has a number of advantages and disadvantages compared to conventional mechanical forming techniques.
Some of the advantages are;
- Improved formability (the amount of stretch available without tearing)
- Wrinkling can be greatly suppressed
- Forming can be combined with joining and assembling with dissimilar components including glass, plastic, composites and other metals.
- Close tolerances are possible as springback can be significantly reduced.
- Single sided dies are sufficient which can reduce tooling costs
- Lubricants are reduced or are unnecessary, so forming can be used in clean room conditions
- Mechanical contact with the workpiece is not required, this avoids surface contamination and tooling marks. As a result, a surface finish can be applied to the workpiece before forming.
The principle disadvantages are;
- Non conductive materials cannot be formed directly, but can be formed using a conductive drive plate
- The high voltages and currents involved require careful safety considerations
- Large sheet metal components cannot readily be formed, due to current limitations on the design of very large coils

Famous quotes containing the words comparison with, comparison, mechanical and/or forming:
“What is man in nature? A nothing in comparison with the infinite, an all in comparison with the nothing—a mean between nothing and everything.”
—Blaise Pascal (1623–1662)
“In comparison to the French Revolution, the American Revolution has come to seem a parochial and rather dull event. This, despite the fact that the American Revolution was successful—realizing the purposes of the revolutionaries and establishing a durable political regime—while the French Revolution was a resounding failure, devouring its own children and leading to an imperial despotism, followed by an eventual restoration of the monarchy.”
—Irving Kristol (b. 1920)
“Prejudices are so to speak the mechanical instincts of men: through their prejudices they do without any effort many things they would find too difficult to think through to the point of resolving to do them.”
—G.C. (Georg Christoph)
“Piety is the fermentation of the forming mind and the putrefaction of the disintegrating one.”
—Franz Grillparzer (1791–1872)
