Trends for stainless steel tube in automotive applications

September 13, 2005 | By Kate Bachman

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.

Want a firsthand look at manufacturing in China?

September 13, 2005 | By Eric Lundin

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.

9 Questions About Annular Cutting

September 13, 2005 | By Darwyn Jones

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.

Taking a look at automated spray control:

September 13, 2005 | By William J. Kohley

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

Bend allowance and springback in air bending

September 13, 2005 | By Ninad Nargundkar

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.

Pressing through power failures:

September 13, 2005 | By John Meyer

When BMW Dingolfing (Germany) decided to modernize one of its transfer presses, the desired benefits included increased line availability, increased production through the use of an electronic transfer system, and reduced maintenance. However, one of its highest priorities was to minimize or eliminate the risk of production loss caused by interruptions to the power supply.

No good deed goes unnoticed

September 13, 2005 | By Stephanie Vaughan

Being a good welder often means more than on-the-job performance. Whether it's volunteering to help others or otherwise giving back to one's community, these welders are examples of so many who take their time to give of themselves on the job — and outside the office.

Resolving the challenges of welding coated steels

September 13, 2005 | By Kevin Lyttle

The increased use of coated steels has resulted in an intensified search for solutions to the problems posed by joining these materials. High levels of spatter and welding fume, weld porosity, and poor bead shape are common. These problems lead to increased post-weld cleaning costs, reduced quality, greater rework, and an overall reduction in productivity. The right wire size and type, matched with the most appropriate shielding gas, can substantially improve gas metal arc welding (GMAW) performance on galvanized and coated steels.

A focus on slitting lines

September 13, 2005 | By Ken Shoop

As manufacturing has moved overseas, the U.S. slitting market has become saddled with overcapacity. Coil processors can improve efficiencies by upgrading the equipment they use in the following areas: coil storage, changeovers in coil and slitting tooling; scrap handling; and tensioning.

Software brings new intelligence to press brakes

September 13, 2005 | By Todd Kirchoff

The types of press brake projects that remain in the U.S. tend to be those requiring smaller lot sizes, shorter turnarounds, and more complex shapes than those going offshore. Enter the need for smart press brakes—those with the capability to store and apply process intelligence. Today's shrinking lead times and smaller lot sizes demand more frequent setups, which cut into production hours. Graphical machine controls and offline programming can help maximize operational time by eliminating the time for trial-and-error setup and improving first-part accuracy.

R&D Update: Air-assisted forming of aluminum alloy for automotive components

August 9, 2005 | By Taylan Altan, Ph.D.

Reducing weight while maintaining or improving functional requirements is one of the major goals of automotive design and manufacturing, as it decreases fuel consumption and improves structural design. As a result of these considerations, the use of aluminum alloys in car manufacturing continues to increase, not only in body panels but also in structural, power train, and suspension components.
