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.

Forming products from advanced high-strength steels is a challenge. Understanding how these materials react during press feeding, straightening, blanking, and forming is necessary in designing production processes that run as efficiently as possible.
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...

To improve a process, you need to measure the results and compare them against expectations. In many instances, a metal former needs to define key performance indicators and keep track of them to determine just how its shop is performing.

Software integration that links toolroom data and processes with the rest of the company can uncover time savings, harmonize schedules, and unleash a wealth of information from which management can improve the business.
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.

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.

Metal formers are more than just suppliers of stamped parts. They understand how material reacts during the forming process and how downstream processes can be set up to handle stamped parts efficiently. This is valuable knowledge and should be shared with customers to solidify relationships and possibly boost revenue opportunities.
Metal spinning and flow forming are similar processes. In some respects, flow forming can be considered a specialized kind of metal spinning. But the two processes are different, and each is designed to meet different application requirements.
