U.S. stampers are missing an opportunity to gain a competitive edge by offering materials engineering support, which often is lacking within OEMs and Tier 1 suppliers. Many stampers take the position that they "just build to a print"—but so do overseas shops.

Today's laser sources have the power and beam quality needed to cut and join metal in an expeditious and repetitious manner. The market demands that type of flexible production, so those characteristics are basic requirements in modern laser devices. The market demands also have promoted the idea of multifunctional processing. That has led to the development of a combination head capable of laser cutting and welding 3-D metal work pieces.

Although a firm grasp of laser physics, metallurgy, tooling and fixturing, weld process parameters, and part strength testing is necessary to implement laser technology in any manufacturing facility, it's also critical to think of other issues that will impact the success of your laser use. Some keys to a successful laser project include involving production personnel early in the process, choosing a laser technology advocate, considering your shop's ambient environment, using trained operators and maintenance personnel, and planning for spare parts and maintenance.

The quality of resistance-welded components depends on the weld schedule, which comprises several machine settings. Although many resistance welding machine and electrode suppliers offer standard weld schedules for common metal combination, special weld schedules often are necessary to address increased use of special metals, joint combinations, coatings, and weld-through sealants and adhesives.

Evidence that stainless steel has potential as a material for automotive components—for its high strength-to-weight ratio for overall weight reduction, good dent performance, corrosion resistance, and formability—was presented by ISSF members at the SAE International™ 2004 SAE World Congress, in Detroit.

China has been in the news extensively during the past couple of years, and developments in 2005 have intensified the focus on the world's most populous country. Chinese companies Hair and China National Offshore Oil Co. put in bids on U.S. companies (Maytag and Unocal); meanwhile, the People's Bank of China unhooked the yuan from the dollar in favor of linking the yuan to a basket of foreign currencies. This is the perfect time to embark on a tour to get a better understanding of the country's manfacturing capabilities, so FMA, TPA, and Thermatool Corp. teamued up to organize the tube- and pipe-oriented tour of the country.

One way to avoid dimpling and deburring while making holes in tube and pipe is use annular cutters. Because annular cutters are hollow, there is no dead-zone resistance to overcome. Knowing how to use an annular cutter and what to watch for can help avoid problems and extend tool wear.

Spray systems often are regarded as simple on-off valve and regulation systems. In reality, though, spray nozzles are precision components designed to yield very specific performance under specific process conditions. Just because nozzles are spraying doesn't mean that they are spraying precisely, and precision spray performance makes a difference in throughput, quality, and bottom-line profits

This study illustrated that, when the thickness and stress-strain curve of the sheet material are known, it is possible to predict with acceptable accuracy the bend allowance, springback angle, and punch stroke to obtain the desired final product dimensions.
