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.

Advanced technology in the metal stamping industry has rendered obsolete traditional methods of selecting, specifying, and supplying material. Using modern technology to quantify materials can reduce the occurrence of material variation exceeding the die and process capabilities and make die development a much more efficient process.

In draw forming, measurement and quantification are essential to ensuring part quality for the customer. However, the product requirements and the product input variables have different metrics and different conceptual meanings, which seems to defy direct engineering. Three processing variables can be adjusted during production to ensure the part is formed correctly.

In recent studies, dry-film lubricants have been shown to give better lubrication conditions compared to oil-based liquid lubricants. This factor, as well as savings in the amount of lubricant used, has helped increase the use of dry-film lubricants in the automotive industry for forming of aluminum and high-strength steel stamped parts.

In any stamping process including progressive dies, transfer dies, or line dies, three factors are essential to consider when processing a piece of flat metal into a finished part: What is the metal? What is the metal's thickness? What are the part tolerances?

Figure 1 Part VII of this series introduced two basic types of metals used to manufacture stamped parts—ferrous, metals that contain iron, and nonferrous, metals that do not contain iron. This article discusses the specific mechanical properties of these metals in more detail.The metal's...

Self-piercing riviting, an alternative sheet joining method, is being used more to join aluminum sheets. The finite element method can be employed to study the SPR process and joints, perhaps even leading to the elimination of physical testing of these mechanical joints.

Draw forming is one of the net shape processes, and, as a result, many of the technology advances in the general field of manufacturing have not been as beneficial to draw forming as one would expect. All too often, such advancements as lean manufacturing, statistical process control, just-in-time, and six sigma, have not resulted in benefits for draw forming.

Cosma International applies its own hot-forming technique to stamping automotive metal components such as A and B pillars, roof headers, roof rails, rockers, door intrusion beams, and bumpers, to meet new CAFE standards for weight, NHTSA requirements for strength, and to counter problems with springback in UHSS components.

A die transport system may be needed if current production requirements cannot be met with existing presses, and opportunities for additional contracts are limited by current equipment production volumes; parts can be produced competitively in large batches, but not if the part count is smaller; and shop safety needs to be improved.

In 2005 precision stamper Weiss-Aug of East Hanover, N.J., achieved a reject rate of less than 1 part per million. The company credits the success to meticulous planning and almost flawless execution. Such an approach applies for Weiss-Aug even when it comes to uncoiling metal.
