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.

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 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.

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.

More than 4.5 million tons of coil-coated steel and aluminum are processed in North America each year by manufacturers in the appliance, auto, machinery, heating and cooling, metal roofing, and beverage industries. Gaining insights into stamping, handling, tooling, and storage can help optimize results

The catch to operating at higher production speeds is that metalformers often see jumps in scrap rates and accelerated wear-and-tear on the press and tooling. New, and some tried-and-true, mechanical press technologies help metalformers strike a balance between high speed and high precision.

Active leveling control (ALC) counteracts the negative effects of off-center loading; significant breakthrough shock common with high-strength steels (HSS); and reverse shock loading associated with nitrogen springs in dies.

Editor's Note: This is the second part of a two-part article about reading progressive-die strips. Part I, which appeared in the May issue, covered the causes of pilot hole distortion and mismatched cuts. Hard marks, otherwise known as coin marks, occur when metal is severely squeezed between two...

Looking at the results of a process—in this case, the strip produced in the die—certainly can lead to good data indicating the root cause of a problem. This Part II of a two-part series discusses hard marks, poor die design, and coil-related problems.

Changes come often in the steel industry--a business that sticks around long enough might eventually bear little resemblance to the version established at its inception. This is the case for Parkview Metal Products, Lake Zurich, Ill. The company opened in 1950 as a tool and die shop in Chicago, later moving and shifting its focus to automotive, electronic, and grill components. The company believes its culture is changing for the better and plans to continue developing its 5S initiatives, increasing its on-time delivery, and reducing its scrap rate.

Converting a current press to a transfer press requires altering the press, transfer dies, and the transfer system. Some presses are suitable for conversion, some are not. With a proper transfer retrofit, an old press can become a fully programmable state-of-the-art transfer press.
