Applications
Induction Forging: Uses induction heaters to pre-heat metals before forging, typically heating to between 1,100 and 1,200 °C to increase malleability and aid flow in forging dies. Benefits include less oxidation, easy temperature and time control, rapid heating, improved forging quality, and protection of forging machine tools.
Induction Brazing: A metal-joining process where two or more metal items are joined by melting and flowing a filler metal into the joint, with the filler metal having a lower melting point than the adjoining metal.
Induction Bending: Uses inductors to locally heat pipe or tube while an accurate drive system pushes the material in a desired radius. The hot section forms at the set radius and is then cooled by water. Widely used in oil and gas industry with bending range of diameter 159-762 mm and thickness 5-35 mm.
Hardening Induction Heating: The most common form of heat treatment, widely used on shafts, gears, pipes, and other parts in the automotive industry. Induction power is applied to the surface, heating to required depth, then cooling rapidly with water, oil, or other cooling medium.
