STAMPING Journal is the only industrial publication dedicated solely to serving the needs of the metal stamping market. In 1987 the American Metal Stamping Association broadened its horizons and renamed itself and its publication, known then as Metal Stamping.
Editor’s Note: This article is Part II of a two-part series. Part I, which appeared in the November/December 2016 issue, discussed the challenges of determining Young’s modulus, one of the most important parameters for springback prediction.

Some stamping plants and die-building facilities are far more productive and efficient than others. Each shop typically has its own niche, as well as its own strengths and weaknesses. So what are the key decisions managers make that result in a successful stamping or die-building shop? Staffing...

Q: We are developing what we thought would be a fairly straightforward stamping. We are blanking a rectangular shape, 2.15 by 2.35 inches and 0.004 in. thick, from 301 stainless steel. A simple, single punch blanks the part through the die chase in one shot. But as we brought up the stamping speed...

Considering the competitive state of the automotive industry, any kind of best practices sharing and collaboration among automotive OEMs would seem counter-intuitive. Yet, on the important topic of the environment, major automakers and top suppliers have been doing just that since they formed the...
Editor’s Note: Part II of this article, which will appear in the January/February 2017 issue, will discuss the results and case studies of the newly introduced inverse analysis method for improving springback prediction. In the automotive industry, the use of advanced high-strength steels (AHSS)...

Before receiving a contract to design and build a die, the building shop must quote a price to the customer. Because every die usually is a one-of-a-kind tool, the process of quoting tooling cost is not always easy. The person estimating this cost must have a good understanding of sheet metal...

The “10 Die Design Laws,” which appeared in the September/October 2016 issue, are most effective when used along with a continuous improvement approach. At the end of every tool build and final development cycle, the die design team should review what went well and build on those strengths, but...

Compact in-die transfer tooling technology brings the flexibility of a press-mounted transfer system to small-press and small-part applications. The small transfer system mounts directly to the stamping die, becoming part of the die. The in-die transfer tool is set up and run in continuous mode, just like a progressive die.

Profitable part processing begins with a small footprint. a compact coil line does not need a loop and pit because the coil is mounted above the leveler and feeding mechanisms. A compact line has many of the same capabilities as a conventional line but occupies less floor space and, often, with simplified operation. Even at its small size—less than half the size of a standard line—it can handle thick and strong materials. These floor-space savers can process coils up to 20 tons with widths up to 59 inches (1,500 millimeters) and thicknesses between 0.031 and 0.47 in. (0.8 and 12 mm).

If an ounce of prevention equals a pound of cure, what is it worth when you’re stamping thousands of tons? To Rockford Toolcraft, it’s priceless. The $100 million annual sales stamping manufacturer specializes in stamping heavy-gauge material up to ¾ inch thick. Its maintenance, repair, overhaul program must be topnotch to keep operations moving. The millwrights and electricians who maintain, repair, and overhaul the 60 massive, high-tonnage mechanical presses are highly skilled, very experienced, and ready at a moment’s notice to get the presses back on track ASAP. Here’s how the company keeps its fleet of presses humming.
Lubrication plays an important role in sheet metal forming by affecting metal flow and reducing the possibility of fracture during forming. A number of tests are used to evaluate lubricant performance, including the strip draw test, the twist compression test, and the cup drawing test.The cup...
