Advanced lubricants improve high-strength steel forming

March 8, 2005 | By Brad Jeffery

Advanced or ultrahigh-strength steel (AHSS or UHSS) use in more than 60 percent of structural automotive stampings has changed the rules when it comes to tooling surface, heat and friction control, robotic automation, and paint pretreatment. With yield strengths now reaching production levels of...

The cutting edge of cut-to-length lines

March 8, 2005 | By Alexander Tschoeltsch

When a company plans to invest in a cut-to-length line, basic line configuration is the first decision—and one of the most important—to make.The fixed-shear line is a common configuration. It can be an entirely stop-start (or "tight") line, or it can include a decoiling and leveling...

The real issues behind hydraulic press upgrades:

February 8, 2005 | By Gerry Nord

Upgrading any piece of machinery can produce anxious headaches. Often we cause our own headaches by failing truly to justify the reasons to upgrade, choosing instead simply to answer the question, "Can we afford to spend the money?"Answering that question is really easy. Either the money's...

Implementing a stamping sensor program—uphill

January 11, 2005 | By Kate Bachman

Stamper and toolmaker Ultra Tool & Manufacturing, Menomonee Falls, Wis. had been installing basic stamping die protection for 15 years. Whisker sensors, positive stops, and, in some cases, part-out sensors comprised the limited sensor system for dies that ran in automatic mode. However, this system...

Finding simplicity and efficiency in servo press feeds

December 7, 2004 | By Brian Landry

Upon their debut in the 1960s, servo press feed systems were hailed as the technology for the future. They were recognized for their productivity advantages, a result of digital setups that quickly dialed in feed length and speed parameters, with controlled acceleration and deceleration rates, job...

Regaining flatness in stamped parts

December 7, 2004 | By Art Hedrick

Of all the geometric tolerances that are difficult to achieve, flatness is one of the hardest. Most stampers probably would much rather try to make a complex-shaped, thin, high-strength steel deep-drawn part than hold a small-tolerance part requiring a tight flatness.Achieving part flatness is a...

High-performance coating helps stamper fight downtime

December 7, 2004

Depending on the severity of the application, some stamping dies require frequent reconditioning or recoating. However, some coating processes are done at such high temperatures that the dies become distorted and unuseable, requiring further regrinding. Omni Mfg. encountered this problem in stamping a heavy-duty hinge. It then discovered FortiPhy UltraEndurance™ from Phygen Inc., which increased the hit count on its dies from 20,000 to 200,000 between recoatings. The coating is applied at a relatively low temperature, so distortion is not a factor.
