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.
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.

Ensuring part quality and protecting dies are important considerations for any stamping operation. In-die analog sensors can help stampers reduce setup errors and downtime while achieving optimum part quality. This article discusses different applications for analog sensors.

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 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.

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.

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.

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.

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.
Equations help leveler operators significantly reduce the traditional trial and error during setup.

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.

Today's escalated metals prices have made scrap a hot issue. Multi source article covers new trends and old favorites in efficient scrap handling and in minimizing scrap
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.

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.
