All businesses tied to the metal forming industry are scrambling to find areas in which they can lower costs without sacrificing quality. Adding to this burden are a tight cash flow and a lack of financial resources to invest in process improvement equipment. Therefore, the savings must come from doing more with less.

The trend in metal stamping is to use more and more aluminum and other lightweight materials, such as advanced high strength steel (AHSS). The need for technology to help improve metal flow of these materials in deep-drawing applications also is increasing. In many cases, a stamper's original...

Switching from an oil-based lubricant to a water-based gel lubricant helped an exhaust-system components manufacturer, Zeuna Starker, reduce costs and cycle time. After studying several types of lubricants, the company chose a water-based gel that was less prone to spilling onto the floor and did not produce smoke during the welding process. The company reaped benefits in decreased housekeeping and disposal costs, and found that it did not need to wash the lubricant residue from semifinished parts before welding.
