R&D Update: Examining lubricant performance in forming of AHSS

February 5, 2015

By: , ,

Lubrication plays an important role in stamping, as it reduces friction at the tool-workpiece interface. Reducing that friction also reduces die and tool wear in large-volume production, which in turn increases tool life. It also allows smoother flow of the sheet material into the die cavity and...
