Advanced hydraulics and intelligent drive systems are now available to provide greater metal forming precision and to improve stamping press productivity and product quality.
: Stamping AHSS comes with forming challenges such as wrinkling, tearing, and springback. A servo’s controlled force can help resolve some of those problems—and keep you from tearing your hair out.

Q: We have some manual presses set up in a single part load-and-stamp production mode. The press is equipped with light curtains. When the operator activates the press buttons, he has to wait until the tool runs through the entire press cycle before he can reach into the work area. If he tries to...
The Ohio State University's Center for Precision Forming provides an overview of design considerations and materials used in lightweighting in the automotive industry in the first part of a two-part series.

It’s amazing how many stampers and tool and die shops negate the importance of the press. Shops often “maintain” a press when it stops working. In other words, they repair the press, but they don’t maintain it regularly. I could have just as easily named this article “How to select...
Finite element (FE)-based computer software commonly is used in the sheet metal forming and stamping industry for die design and for predicting metal flow and thinning in the formed part. It is a useful tool for predicting and preventing forming defects such as fracture and wrinkling. However,...

Q: We are in the process of quoting a new job for the swaging and stamping of copper rod. To do this job, we need to buy a hydraulic press. The goal is to deform copper rods into a flat form on one of the edges. How do we calculate how much press tonnage we need? A: Obviously I would need a...

I must get two or three calls a week from companies needing tool- and diemakers, die maintenance specialists, or die repair specialists. The demand for skilled labor has skyrocketed in the last year or so. Unfortunately, most of the time I can’t help them. The Dwindling Talent Pool...

Often, transfer dies are designed, built, and installed in a press, and then stamping manufacturers discover that they have crash interference problems. Then diemakers are sent to fix the problems, but the solutions slow down productivity. Running transfer dies through simulation software first can circumvent those problems.

Quality Industries made a U-turn on its decision to let its stamping department stall and has reignited the department’s restart with a press retrofit, quick die change (QDC) equipment, and a new press.
As corporate average fuel economy (CAFE) standards require increasingly lighter vehicles, stamping manufacturers look for innovative ways, such as hot stamping, to form increasingly harder metals. Hydraulic presses have been the default technology for hot-stamping presses. Now servo-mechanical presses have entered the arena that hydraulic presses previously soloed, offering improved energy efficiency, cycle time, and reliability.

In a few years Performance Stamping may well be a very different company. It recently cleared away inventory to free space not for more stamping, but for metal fabrication.
