Calendering is a cold forming process that allows metal sheets or strips to be bent according to predetermined radii and geometries. The material is passed between opposing rolls that exert controlled pressure, changing its curvature in a progressive and uniform manner.

This technology is ideal for making cylindrical, conical or arched components, ensuring accurate, repeatable results with excellent surface finish. Calendering can be integrated into automated lines and combined with other machining processes, such as welding or robotic assembly.

There are different types of calenders depending on the machining to be done and the shapes and geometries required.

The integration of automated systems has revolutionized the calendering process. Position sensors, numerical controls (CNC) and human-machine interfaces (HMIs) enable precise roll adjustment, ensuring uniformity and repeatability in production. Automation also enables rapid setup of processing parameters, reducing setup time and increasing production efficiency.
