Electric upsetting combines heating and gathering of bar material in one process. The technological limits of other forming methods can partly be overcome by electric upsetting. In valve production, for example, the ratio of upset length and bar diameter can be increased up to a factor of 20:1.
LASCO offers horizontal (EH) and vertical (EV) electric upsetters, as well as special designs. They may be combined with suitable finish-forging equipment with handling systems to create efficient fully automatic production lines.
