Ema supplies semi and fully automatic induction heating systems, which can be applied in various areas, design and production both being elaborated and realised in its own factory. This is also valid for the machinery to be applied and the necessary controlling devices as well as for the frequency converters. In comparison with conventional furnace hardening, induction hardening systems offer various technological advantages as mentioned in the following: short hardening periods and, as a result thereof, nearly scale-free hardening zones [if required, hardening under protective gas is possible]; reduced distortion owing to hardening process; reproducible results; and exactly defined local hardening [also possible at bulky workpieces]. The company offers flanged table, mounted onto the vertical traverse hardening machine which is appropriate for tooth-by tooth hardening of internally or externally geared sprockets. Applications of induction hardening: peripheral surface hardening, tempering, annealing and flared flange heating at body components and shrinking-on.
