Cold

Aluminum Cold
Cold rolling can provide a smoother surface finish than hot rolling. It is also used for thinner products which must be cold-rolled to their final thickness.  

It takes more energy to roll cold metal than that softened by heating, so an efficient process reduces production costs. Cold mills can operate at roll speeds up to 7,000 ft per minute, making automated inspection essential.

Cold-rolled aluminum is subject to several applications during the manufacturing process, all of which benefit from high levels of surface inspection and defect monitoring to ensure product quality.

AMETEK Surface Vision delivers trusted, highly accurate solutions for continuous processes, maintaining line speeds and rapidly detecting defects. Automation options provide reliable inspection even at fast roll speeds.
  • Applications +

    • Aluminum Annealing
      Annealing

      Prior to cold treatment, the metal can be annealed to soften it and improve machinability. This process can also repair surface defects – the success of this can be monitored by a reliable inspection system.
