Choosing the right hydraulic press for your application is crucial. Identifying the right press capability up front can eliminate additional costs and startup delays. Four primary hydraulic press return capabilities are return on position, return on pressure, return on pressure with dwell capability, or combinations of the three. Shown is a press with return on pressure capabilities.

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.

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.

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

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.

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.

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.

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.

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.

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...
