Stamping Articles

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.

Optimal tooling approaches for punching AHSS

March 3, 2014 | By Bruce Konopinski is

The tried-and-true approaches that worked well to stamp first-generation steels are not as effective for stamping advanced high-strength steels (AHSS). Tests were conducted to determine optimal punch-to-die clearances, shear angles, and punch angles. Test results indicated that 12 to 15 percent punch-to-die clearances and -15- to +15-degree shear angles provided the longest punch and die life, and a 7-degree conical shear angle created the smallest burr growth.

Cutting time between coils

January 27, 2014 | By Tim Qualls

Excessive press downtime between jobs is stamping’s perennial albatross around the neck. To expose the culprits in your shop, try scrutinizing every step in a coil handling system, from the coil itself to the material pilot guides in the tool.

Make your hydraulic stamping press retrofit energy-fit

November 1, 2013 | By Jan Komsta, Jeff Grube, Werner Wolf

Most stampers don’t think twice about running a hydraulic press like it has been run for the last 20 years. By doing so, they are losing out on dramatic cost savings associated with a possible energy-saving retrofit that’s centered around a smart variable-speed pump drive.

Establishing a die preventive maintenance program, Part I

November 1, 2013 | By Tom Ulrich

To realize the importance of a good die preventive maintenance program, all a stamper has to do is recall the last time a press line shut down because of a major die problem. The downtime and reaction of the frustrated customer likely are hard to forget. The associated costs, however, aren’t typically documented. That shouldn’t be the case, because those costs can be very important in trying to convince management that a robust tooling maintenance program is worth every cent invested in it.

Leveling beyond the coil

June 28, 2013 | By Jurgen Jost

Not all metal forming jobs are done off the coil, so what can stampers do to ensure that the metal is level? They can use a stand-alone hydraulic roller leveler to ensure parts meet original specs.

An overview of tooling coatings

June 28, 2013 | By Bernie Janoss

The ranks within the tool and die community have thinned with the shop closures and business consolidations that followed the Great Recession. As a result, the depth of knowledge about tooling coatings has decreased as well in recent years. This primer is intended to provide a quick explanation of the most common tooling coatings for those that need a quick education.

R&D Update: Warm forming of alloys in the auto industry

June 28, 2013 | By Eren Billur, Taylan Altan, Ph.D.

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.

Quick die change: About the time in between

April 22, 2013 | By Carol Herriges , John Remington

Boiled down, quick-die change covers all activities that occur between one job and the next. QDC boils down to reducing those activities by eliminating them altogether, making those remaining activties more efficient, and changing when those tasks are performed.

The reinvention of stamping

February 28, 2013 | By Dan Davis

The days of 1 million unit orders for simple metal blanks are over. But this doesn't mean that stamping can't survive in today's manufacturing environment. A.T. Wall Co. believes it can successfully position stamping as a go-to manufacturing process for parts that were at one time exclusively made through machining.
