Case Histories for Metal

Metal - OEM, System Integrator, End User
SAG - Slitter and cut-to-length lines

SAG - Slitter and cut-to-length lines

SAG uses roll forming machines with flying shear system.
The production speed creates various design problems regarding mechanics and movement control. Gefran studied for SAG a highly dynamic control system.

Metal - OEM
Faccin - Plate rolls

Faccin - Plate rolls

For over 60 years, Faccin has been the leading manufacturer of plate rolls, angle rolls, and production lines for dome ends. In the metal plate rolling process, it is extremely important to control the main process parameters, such as roll position and oil pressure and temperature. Gefran is Faccin’s ideal partner because it offers a complete range of sensors, from position to temperature, to satisfy the customer’s needs.
