The amount of time a line is nonproductive between coils can vary. It's not uncommon for downtime to exceed 20 minutes. On heavy-gauge lines, where a coil's linear footage is low, the amount of downtime can be excessive. Pax Machine Works, Celina, Ohio, produces products that are drawn, deep-drawn, blanked, pierced, coined, extruded, and embossed. Its finished parts are sold to OEMs and aftermarket pa...

According to the Association of Home Appliance Manufacturers (AHAM), the use of stainless steel in home appliances has increased in the last five years and is expected to continue to grow. Nearly 20 percent of all ranges, dishwashers, and refrigerators sold have a stainless steel finish. Additionally, microwaves, outdoor grills, and even washers, dryers, to...

Metal fabrication is one of the most competitive industries in the U.S. Fabricators are always looking for new ways to decrease manufacturing costs to maintain profitability and a competitive edge. Identifying and implementing cost-reduction opportunities... Lloyd Wolf Tue, 10 Apr 2007 12:00:00 AM CDT http://www.thefabricator.com/CoilProcessing/CoilProcessing_Article.cfm?ID=1601 The composition and construction of a roll, its fabric, and how it is finished are critical in understanding how a roll works. Knowing how a roll works, in turn, is the key to optimizing its performance and longevity. A nonwoven fabric is a combination of natural or synthetic fibers and molten plastics intertwined to form a base or web. Because the roll fabric comprises fibers that vary in diameter and length, the fabric's strength and flexibility exceed that of any of the ind... Jim Rusczyk and Doug Goetz Tue, 10 Apr 2007 12:00:00 AM CDT http://www.thefabricator.com/CoilProcessing/CoilProcessing_Article.cfm?ID=1570 Editor's Note: This article is adapted from Brownie Cox's conference presented at FABTECH® International & AWS Welding Show, Oct. 31-Nov. 2, Atlanta,© 2006 by the Fabricators & Manufacturers Association Intl. (FMA), the Society of Manufacturing Engineers (SME), and the American Welding Society (AWS). The science of leveling metal strip has two main goals. The first is to make the metal's surface flat and ripple-free. The second is to neutralize hidde... Brownie Cox Tue, 13 Mar 2007 12:00:00 AM CST http://www.thefabricator.com/CoilProcessing/CoilProcessing_Article.cfm?ID=1564 Traditional slinging and hoisting of coils for mounting on vertical dereelers or positioning them in coil cradles requires extra personnel and is time-consuming because production must be stopped. When a line isn't running—it's not making money. To keep their lines moving, some stampers use a horizontal pallet uncoiler. Horizontal uncoiling calls for the placement of several palletized coils on top of each other on the uncoiler turntable. When the top coil ... Tim Malarky Mon, 19 Feb 2007 12:00:00 AM CST http://www.thefabricator.com/CoilProcessing/CoilProcessing_Article.cfm?ID=1455 More than ever manufacturers depend on high-quality blanked and stamped parts to reduce production costs, speed up assembly time, and eliminate secondary processing requirements. The automotive market in particular is focused on consistently achieving uniform and accurately dimensioned parts. Automotive blanking and stamping supplier SET Enterprises needed to eliminate shape defects caused by the mill strip production process for ferrous and nonferrous coils. These shape defects v... Tue, 12 Sep 2006 12:00:00 AM CDT http://www.thefabricator.com/CoilProcessing/CoilProcessing_Article.cfm?ID=1448 Minimizing coil processing scrap maximizes yield. Nearly everyone who processes metal—aluminum, carbon, or stainless steel—is concerned about scrap loss. Scrap loss in coil processing operations, such as slitting, cut-to-length, and stamping, often is overlooked. Finding ways to minimize scrap loss in coil processing operations will maximize your yield and improve your bottom line. In many cases, automating scrap handling will also improve efficiency and promote a s... Ken Shoop Tue, 12 Sep 2006 12:00:00 AM CDT http://www.thefabricator.com/CoilProcessing/CoilProcessing_Article.cfm?ID=1418 Figure 1In the mid-1980s service centers attempted to create coils slit in a scroll pattern to reduce scrap. When processing round or nested parts, most stampers use one of these three methods with varying degrees of scrap rates: Conventional coil stock feeding into a one-out die. This method results in an extremely high scrap rate. Coil stock feeding into a multiple-out die. This technology results in greater material savings than one-out dies, but tooling cos...
