Warm forming of alloys in the auto industry

June 28, 2013

By: ,

While stampers struggle with traditional forming of aluminum alloys, particularly in the automotive industry, they should know that research is currently underway to make this tough job easier. Warm forming of certain aluminum alloys is a real possibility when it comes to stamping parts from these difficult-to-work-with materials.

Update: Hot-stamping boron-alloyed steels for automotive parts

March 10, 2011

By:

CPF has conducted experiments using finite element simulation of the hot stamping process. The process can help manufacturers predict such final part properties as thickness, temperature, and hardness distribution.

Lubrication and galling in stamping of galvanized AHSS

April 15, 2008

By:

Forming of galvanized AHSS involves higher contact pressures at the tool-workpiece interface compared to forming mild steel. Under these severe interface conditions, improper selection of lubricants, tool materials and tool coatings may result in high scrap rates and galling in stamping production.. Based on SDT results, polymer-based lubricant with EP additives and water-soluble DFL were found to be most effective, Synthetic lubricants showed also reasonably small frictional responses with a PVD coated die in forming GA coated strips.

Blanking developments - Part III

September 11, 2007

By:

During high-speed blanking, press stroking rate and punch speeds, are higher than in conventional blanking. As a result, the shear zone has a higher strain rate, which affects a workpiece's sheared surface temperature and the tool surface.

Stamping research gains support

June 12, 2007

By:

Global competition continues to force the metal forming industry to reduce costs, improve technology, and increase productivity. With these trends in mind, the Ohio State University (OSU) and Virginia Commonwealth University (VCU) established in June 2006 the Center for Precision Forming to focus on the needs of the metal forming industry.

Servo press forming applications

May 8, 2007

By:

A servomotor gives a press slide motion flexibility in terms of accurate speed, motion, and position control. This flexibility produces infinite slide motion variations that may improve part quality and operations such as painting and assembly during one press stroke.
