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.

Overseas competition, high material costs, just-in-time schedules, demanding quality requirements, stringent safety standards, and industry consolidation are the forces driving trends in the quick die change industry, industry experts say. These forces have intensified the need for quick-die-change equipment and processes, as well as for larger quick die change equipment, equipment that will not damage sensors, and more efficient die storage that can be integrated with quick die change equipment.

All presses go up and down, but that's where the similarity among them ends. When its time to review your pressroom and research a new press, consider your manufacturing needs, the parts the press will run, all ancillary equipment, raw materials, and the dies that will be making the parts.

BTD made its first investments in tube fabricating equipment, including a BLM-Adige 803D tube laser cutting system, in 2003. Now tube fabricating accounts for roughly 15 percent of its total business. The story is short, but not so sweet. Paul Gintner, CEO of Detroit Lakes,...

Reducing die changeover times is mandatory to become a world-class stamping operation. The most practical way to accomplish it is through careful evaluation of pressroom needs, and the implementation of cost-effective die change equipment and procedures. In today's manufacturing environment, lean budgets are a way of life, which makes retrofitting die change equipment a cost-effective approach.

Figure 1EmbossingAll forming operations deform sheet material by exposing it to tension, compression, or both. Most part defects, such as splits and wrinkles, occur in forming operations. Successful sheet metal forming relies heavily on the metal's mechanical properties. The metal being formed must...

When considering a die lubrication method, you should be sure to evaluate its effect on your entire operation. While most of us focus on how lubrication affects just the manufacture of parts, a close look reveals that it affects many other aspects of running a plant. However, many of them are not obvious.

Kawasaki's production encompasses several wheel sizes and designs, which require more than 60 different dies. To become more efficient, the manufacturer wanted two complete press lines—one to make round and rectangular blanks directly from coil and one to stamp finished disks.

Figure 1 The radius gauge fits squarely into the bend. Air forming, bottom bending, and coining are different forming methods that can be used to create various bends—sharp, radius, and profound-radius. Throw in a mix of operators and engineers with different ideas of what each...

Bill Engvall and Travis Tritt teamed up on a humorous little song called "Here's Your Sign." This curious little ditty relates the frustration of dealing with modern man's inability to grasp the obvious in daily living. From the service station attendant who stares at the blown-out tire on your car...
The U.S. tooling industry has received quite a bit of press in the past few years documenting its demise. Many people believe the rise of lower-cost tooling industries in foreign countries is the main culprit.Unfortunately, it's not that simple. The U.S. tooling industry's future is precarious, but...

Although mandrel bending is the method most likely to produce a high-quality bend, it is by no means an exact science. Material, size, bend dimensions, and machine variables make it necessary to consider each application individually—and some of these considerations require experience and...
