Die springs put on the pressure

January 10, 2013 | By Jim Wahl

Without something to manage and absorb pressure, a die set would cease to function properly. This is why die spring selection--which considers spring size, travel, number, and placement within the tool--is so critical.

Feed with care

January 10, 2013 | By Jim Ward

Although many of the traditional coil-handling rules apply, processing coated coil material requires additional considerations. Stampers need to check for equipment clearances and alignment at every point where the finished material surface may contact another surface.

Not your father’s fineblanking

January 8, 2013 | By Kaveh Vafaei

Fineblankng now can produce not only flat parts, but also those with 3-D features, often to size and position tolerances of less than +/- 0.025 mm. It also offers extremely high part-to-part repeatability; the first part and the millionth part are identical. A confluence of technologies has made such parts a reality.

Stamper blazes a trail with in-die laser welding

November 9, 2012 | By Dan Davis

In-die capabilities are an important weapon in a metal stamper's arsenal. These capabilities provide the means to create assemblies as a strip of coil quickly moves through a progressive-die setup. Weiss-Aug, East Hanover, N.J., is taking that competitive edge to the next level by offering in-die laser welding to its customer base.

Managing coil more cost-effectively

November 9, 2012 | By Dan Davis

A supply chain is only as strong as every link. That's why more metal formers are leaning on their material suppliers to improve their coil and sheet management. A couple of metal service centers offer up some advice for those metal stampers looking to do more.

Repair, rebuild, or scrap the press?

November 2, 2012 | By Jared Parker

From the perspective of a field service professional, the choice to repair, rebuild, or look for a new press isn't that hard of a decision. It's just a matter of clearly looking at the current shape of the press and what it will take to get it up to performance specs.

How to optimize die-set guiding

September 7, 2012 | By Bruce Edmonds

Ball-bearing die-set guide components are a critical part of the stamping operation. Properly selected, lubricated, and positioned, they improve tool operation and promote longer component life. If they aren’t properly maintained, excessive press downtime may result.

Quick die change, quicker lubricant changeout

September 3, 2012 | By Troy Turnbull

When developing a lubrication strategy for QDC, companies should never consider a component in isolation. Instead, shops should ensure that various elements--including lubricant dilution, nozzle placement, quick-change devices, and intelligent process control--work in concert to prevent errors and shorten press setups.

Developing a servo press knowledge base

August 31, 2012 | By Tim Heston

Since Qualtek Manufacturing invested in its servo presses several years ago, it has been gradually building up a working knowledge base--specific stroke recipes, tooling tweaks, and other information--that has turned out to be valuable intellectual property.

Status update on hot stamping -

Status update on hot stamping

June 13, 2012 | By Dan Davis

Hot stamping has been around since the early 1970s, and it still holds as much promise today as it did then. Imparting strong steel characteristics on lighter-weight metals remains as relevant today as it did then. Today, however, the desire to exploit hot stamping remains strongest in the automotive industry as it seeks to develop lighter-weight vehicles that can still attain five-star crash ratings. The auto industry's work, however, may eventually influence other sectors that crave that combination of light weight and strength.

Quick die clamping: Hydraulic, magnetic, or hydromechanical? -

Quick die clamping: Hydraulic, magnetic, or hydromechanical?

June 13, 2012 | By David Fischer

As more metal formers find themselves taking on more jobs with lower quantities, they have developed higher interest in quick die change. Many want to automate the entire clamping process: Hit a button and the clamps quickly engage or disengage. Hydraulic, magnetic, or combination clamping systems are options for stampers, but they shouldn't think one is necessarily better than the other without a thorough investigation.

Straightening out coil terms

June 13, 2012 | By Thomas F. Hazen

The nomenclature associated with some coil processing equipment suggests they might perform the same jobs, but reality suggests that flatteners, levelers, and straighteners serve completely different purposes for the metal former working with coiled materials.

Nail stamper seeks tooling tough as nails -

Nail stamper seeks tooling tough as nails

April 27, 2012

Powernail, a Zurich, Ill.-based manufacturer of hardwood flooring nails stamps 1 billion of these L-cleats and E-cleats from flat 0.062 steel annually. The company was looking to improve the lifespan of the high-speed stamping dies his company uses to stamp the hardware. The company purchased die sets made of tungsten carbide, which improves the strength and wear resistance. Since then, Powernailís dies last four times longer than they had, tooling changes are less frequent, and it produceshigher-quality nails.

April 27, 2012 | By David Klemm

All machines have a story to tell. Are you listening? Just like a person wo has a cold, the voice of a machine changes when it is "sick." Most times, if you listen, the machine will tell you whatís wrong.
