Stamper performs subassembly superbly

May 21, 2015

By:

DieMasters Inc. grew from a small diemaker shop to a 100-employee stamping contractor. The company added value to its bottom by making assemblies, which now comprise 70% of its revenue. The assemblies are a metaphoric representation of the company itself, which makes products diverse in every way possible—size, type, market, materials, complexity. While Diemasters’ success is the result of a concerted effort, President and CEO Virgil DeLay pulls the company together and keeps the band on cue with a well-defined production system.

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...
