Coil Shape problem

Controlling flat-rolled shape

February 10, 2009 | By Eric Theis, Tom Hazen

What processes do you need to make sure your coil is flat? What is flat enough? You need to determine where you are at the start, where you want to end up, and how to get there. Once you have determined which shape problem you have you can determine which type of equipment is effective in controlling it.

Converting your fluid systems to green

December 15, 2008 | By Milton Hoff

Metal forming, stamping, and washing fluids traditionally have been thought of as "necessary nuisances" to be used once and thrown away. That mindset is changing.Incorporating "green" or environmentally friendly fluids and fluid management systems can extend fluid life and minimize waste, providing valuable cost savings.

In-Die Joining

In-die joining transforms press into assembly system, Part I

December 14, 2008 | By Roger Patton

In-die joining systems help stamping shops to expand their operations to include sub-assemblies and full assemblies without additional downstream equipment and processes, so they can carve out a bigger share of the production work.

Revealing the Magic — Using data and conducting experiments to solve metal forming problems

December 14, 2008 | By Art Hedrick

Effective stamping professionals rely on scientific principles and not magic to determine and correct production problems. Find out how to troubleshoot wrinkles and rips and take corrective action by following a basic procedure that can be modified to troubleshoot almost any stamping issue.

3-D Design Software

3-D die design for a 3-D world

November 11, 2008 | By Raymond Proeber

3-D die design software allows you to build the die on the computer screen, fully assembled and ready to run as if it were built and sitting out on the shop floor. SolidWorks-based Logopress3 software even allows you to then simulate the die running in the press. Even better, it detects crashing and strip feeding interference problems on your computer screen rather than after the die has been built.

Buying time—by welding

October 28, 2008 | By Art Hedrick

You're almost at the end of a production run and your stamping die fails. What do you do? Replace the failed component? Attempt a repair? How do you decide which option is best? These questions—along with basic guidelines for repairing a die by welding—are answered in this article.

Hydraulic Press Hot Stamping

Hydraulic presses for hot stamping meet weight, safety mandates

October 28, 2008 | By Rick Nicholson

Hot stamping of automotive structural safety components developed in response to mandates levied by the U.S. National Highway Traffic Safety Administration (NHTSA) 1 to improve vehicle crash integrity while also reducing vehicle weight to help meet fuel efficiency standards. Heating a high-strength steel (HSS) component of a boron-steel alloy to the austenitic range—a super-heated solid solution state, ~ 1,700 degrees F (950 degrees C)—improved drawability, and then quickly cooling the part in a water-cooled die, or quenching, transformed the crystalline structure, increasing the formed component's strength-to-weight ratio.

Biobased vegetable oil lubricant

Green lubes under a microscope

October 14, 2008 | By Steve Lowery

Stamping parts with vegetable oil is becoming more a reality every day. For a metal working lubricant—whether it be soluble, semi-synthetic, or synthetic—to be USDA-classified as biobased, it must contain, at minimum, 40 percent to 57 percent of renewable resources. Just because a product is biobased, made from a varying percentage of renewable resources, it does not necessarily make it readily or ultimately biodegradable. Green lubricants offer enhanced lubricity and a high viscosity index. These oils are less toxic to the environment and are easier to dispose.

Carbide in tool and die

September 30, 2008 | By Brian Ayers

Carbide is a two-phase, powder-metallurgical (PM) material consisting of a hard material phase and a binder metal phase. The hard material provides the necessary wear resistance, and the binder metal guarantees appropriate toughness. To select the appropriate grade for a tool and die application, it is important to have a detailed knowledge of carbide and how its properties can be influenced.

Virtual engineering software

Next-generation large-tonnage presses rely on new software for virtual integration

September 15, 2008 | By Bernhard Loske, Dietmar Schoellhammer

Operating large flexible press systems without sacrificing speed and quality can be a complex undertaking. New software takes CATIA to the next level. Users can really learn how to "drive" their large presses optimally by virtually integrating the slide motion, the transfer movement in a way that allows 1) the press to be built, 2) the transfer to be integrated and 3) the die to be built to most efficiently run in the system--a quantum leap. Now being used by Ford and Magnum.

3 deadly tool design sins

August 12, 2008 | By Art Hedrick

Among the many factors to consider when designing and building a stamping die are the material to be processed, the press that will run the die, and specified part tolerances. Inadequate knowledge of these factors can contribute to die failure and production and quality problems.
