Whether you're using a high-speed stamping press to make simple parts at breakneck speeds or doing something really tricky, like deep drawing a material that puts up a lot of resistance, the information in this technology area is sure to help. The articles, case studies, and press releases cover stamping presses, lubricants, and materials.

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...

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...

When stamper Ultra Tool & Manufacturing, Menomonee Falls, Wis., ventured upon an opportunity to produce a unique and challenging project for one of its customers, a well-known U.S. motorcycle manufacturer, the company jumped on it and put the pedal to the metal. The road to success, however, would...

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...

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...

Figure 1Even if the scoring is the reason for the split, that doesn't mean that resolving the galling issue will ensure a robust process.I recently had the chance to engage in some very interesting conversation with the head of the sheet metal formability lab for a very large automotive stamper....

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...

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...

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.

As I entered the clean, well-lit Midwest factory one day, I found several relatively new presses and feeder systems. The shop floor appeared to be well-organized, with material steadily flowing into and away from the presses. The employees seemed to know their jobs and were on task.But when I...

Establishing a good buying procedure is a critical aspect of the tool purchasing process. All too often tool supplier expectations are not communicated and executed effectively. Miscommunication can cause you to purchase a die that doesn't produce good parts, needs constant attention, wears out prematurely, or has other problems.
