All metals prices are near their trough points and will probably not bounce back for a couple of quarters going forward. So for all of these metals, that’s a common theme. Markets will bottom out in the first quarter of 2009 and both the pricing and demand will be relatively slow in recovering throu...

The use of high-strength steels (HSS) and aluminum in automotive and other stamping manufacturing is creating forming challenges for tool and die engineers. Forming simulation software, formerly used to predict conventional failure causes, now also enables the stamping tool and die engineer to simul...

The ERC/NSM conducted experiments using round cup tooling to determine the influence of temperature on the limiting draw ratio -- the largest draw ratio of the blank-to-cup diameter that can be drawn successfully.
The FABRICATOR®, 8/8/06
To prevent martensitic transformation in stainless steel during drawing operations, warm forming has been explored. In experiments, warm forming eliminated intermediate annealing operations and substantially increased limiting draw ratio values.

U.S. stampers are missing an opportunity to gain a competitive edge by offering materials engineering support, which often is lacking within OEMs and Tier 1 suppliers. Many stampers take the position that they “just build to a print”—but so do overseas shops.

The spray form process is a new manufacturing technique that offers high alloyed tool steel with uniform carbide size and uniform carbide distribution. With less processing steps than P/M and properties better than ingot cast tool steel, SF is an option that offers nearly P/M performance with a cos...

Forty years ago Ford and Ferrari were engaged in a fight-to-the-finish struggle to take top racing honors. Ford used its GT40 to snap Ferrari's six-time winning streak at the 24 Hours of LeMans, one of racing's most prestigious events. In 2003 the rivalry was back as Ford unveiled the high-performan...

December came, and the Section 201 tariffs went out under the tide of global and World Trade Organization (WTO) pressure. Just when you thought it was safe to go back in the water, material price increases hit the metals industry like a tidal wave that made the tariff increases look like gently lapp...
