It's all about tool selection -- or is it?

May 10, 2005 | By Steve Benson

Figure 1 The radius gauge fits squarely into the bend. Air forming, bottom bending, and coining are different forming methods that can be used to create various bends—sharp, radius, and profound-radius. Throw in a mix of operators and engineers with different ideas of what each...

Reinventing the wheel - Automated line reduces in-process inventory, increases production flexibility

May 10, 2005

Kawasaki's production encompasses several wheel sizes and designs, which require more than 60 different dies. To become more efficient, the manufacturer wanted two complete press lines—one to make round and rectangular blanks directly from coil and one to stamp finished disks.

Evaluating in-house coil slitting

April 11, 2005 | By Jim Russell

As the cost of steel rises and profit margins shrink, small to medium-sized stampers are looking for ways to reduce costs and streamline operations while maintaining quality.One area to consider is the cost of slitting steel.Shops that run 10,000 to 50,000 tons a year usually outsource slitting....

Automatic lubrication application

Optimizing spray nozzle performance for lubrication:

April 11, 2005 | By Bob Adams

Although mandrel bending is the method most likely to produce a high-quality bend, it is by no means an exact science. Material, size, bend dimensions, and machine variables make it necessary to consider each application individually—and some of these considerations require experience and...

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...

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 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...

Sensors help stamper get firmer foothold in motorcycle part fabrication

February 8, 2005 | By Kate Bachman

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...

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...

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.

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...
