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

February 5, 2015 | By Ali Fallahiarezoodar, Taylan Altan, Ph.D., Suraj Appachu

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...

The pursuit to be the best value-added supplier

January 29, 2015 | By Dan Davis

Waukesha Metal Products, a metal fabricator and metal former based in Sussex, Wis., wasn't going to survive in the long run being a simple stamper of simple metal parts. It needed to reinvent itself and constantly look for ways to evolve if it were to grow and improve its chances of success in the face of more demanding customers. Its in-house knowledge and talent, investment in capacity, and contributions to the overall manufacturing cause are improving its long-term viability. They also have helped the company earn the 2015 Industry Award from The FABRICATOR.
