Mechanized plasma cutting for HVAC applications: How equipment has progressed and what it offers today's fabricatorsJust 20 years ago most heating, ventilation, and air-conditioning (HVAC) ductwork was cut by hand with snips and shears. Cutting out HVAC fittings was slow and labor-intensive. It took an experienced tinsmith with strong hands to slice through galvanized steel all day. It took even more skill to get the cuts and bends just right to coax flat panels of sheet metal into precise 3-D forms.

KNOWLEDGE: The key to welding productivity?: Study's findings have different meanings across manufacturing sectorsIn the year 2000 manufacturing, construction, and mining industries had $34.1 billion worth of welding-related expenses. At the same time more than a half million people in the U.S. had welding-related jobs -- and that's not counting self-employed and nonproduction welders.

Made in the U.S.A.For many years I lived in Belvidere, Ill., home of what was then known simply as the Chrysler plant. The local United Auto Workers union prominently displayed a sign in the parking lot that said, "Foreign cars will be towed." Now that the plant, which builds the Dodge Neon®, bears the name DaimlerChrysler, I'm wondering—is the sign still there? Probably not.

Appliance demand flat: Industry undergoing major segment shifts2007 U.S. appliance shipments are forecast to grow only 1 percent because of a sluggish housing market. Shifts in channel preferences; successful market penetration by offshore brands; a strong demand for high-priced, innovative white goods; and the Maytag/Whirlpool merger are changing the industry's landscape.

Flexibility in the press shop: Arranging equipment to produce a variety of partsTo stay competitive, stampers must be prepared to run a variety of dies, many of which have been designed to run on customized and complex OEM equipment. In addition, stamping concepts tend to differ among the automotive OEMs. For the tier stamper, flexibility is key to surviving these fiercely competitive times.

Retrofit Rxfor automaker's aging press: Modular hydraulic cushion upgrade eases maintenance, improves performanceAn automotive OEM's 4,000-ton transfer press produces parts with difficult draws, such as pickup door panels, in the 1,600-ton first station. Facing problems finding obsolete parts for repair and also considering crucial performance requirements in that first drawing operation, the automaker had Schuler Inc. upgrade the press with a modular hydraulic bed cushion.

New bends in the roll: Roll bending trendsAs more commercial buildings are designed with larger open spaces, the beam spans grow longer, and the beams must be bigger and heavier. This requires ever-larger section bending rolls to accommodate this demand. In addition, the trend toward the use of higher strength steels has taxed the capabilities of plate roll bending equipment. These changes and other emerging demands have driven the trend toward the use of CNCs, inline material handling, and larger angle bending rolls.
