Whether you're using a high-speed stamping press to make simple parts at breakneck speeds or doing something really tricky, like deep drawing a material that puts up a lot of resistance, the information in this technology area is sure to help. The articles, case studies, and press releases cover stamping presses, lubricants, and materials.

Think delicate: an antique vase, velvet gloves, the sweet sound of string music. Then imagine a typical stamping operation: bam-bam, metal on metal, all day long.

Before coiled material can pass through a die to produce an acceptable part, it must be straightened. Coil straightening is accomplished by bending a strip of material around sets of rollers that alternately stretch and compress the upper and lower surfaces so that the material's yield point is exceeded.

One of the cornerstones of an efficient stamping operation is its ability to perform die changes in less than 10 minutes. Retrofitting an entire stamping operation for quick die change can require a very costly investment. Justifying such a large amount of money in a short payback scenario can be impossible.

One way to increase your stamping operation's productivity is to get all the uptime you can from the belt conveyors that carry materials, parts, and finished and packaged products throughout your plant. As moving, wearing equipment, conveyors naturally demand a certain amount of downtime for maintenance and parts replacement. However, keeping those events as infrequent and brief as possible is what uptime is all about.

While it is common knowledge that slit coil handling and packaging often limit the productivity of even the most modern, highspeed coil slitting line, coil processors generally spend too little time examining the effectiveness of these operations.

For about 50 years roll forming was the process of choice for making seat track channels at Dura Automotive Seat Systems, Stockton, Ill. While the process was high-speed, low-maintenance, and flexible, it also caused channel end flare, twist, and bow.

The two main reasons for applying die lubricant are to reduce friction and dissipate heat. Heat can build up between the tool surface and metal, causing the lubricant to break down. This results in metal-to-metal contact and galling.

International Truck and Engine Corporation's Springfield, Ohio, plant recently undertook the challenge of building a high-performance truck with the dimensional tolerances that meet today's quality standards within a cost structure that would allow it to remain competitive. This new product launch was the first of its kind for the company in more than 20 years.

Setting up a stamping die is one of the most critical steps in a successful stamping process. It's a fact: More damage is done to a die, especially a progressive die, in the first 10 hits than in the next 10,000 hits. Most die damage happens during initial setup, when the material is being fed into the die. Mistakes such as misfeeds, pilot piercing, double metal, sheared cutting sections, and stock hang-ups often occur.

Perforating is defined as a process of making a hole by removing a slug. During perforating in a stamping operation, a punch shears and breaks a slug out of the part material and then pushes the slug into a matrix (die bushing). The matrix hole is larger than the punch point. A clearance must be maintained constantly around the entire punch point.

Horizontal payoff of coiled materials on pallet uncoilers can help reduce downtime for coil changeover, increase coil handling efficiency, and improve operator safety.

If you're a die designer, a standard precision progressive die can present countless challenges for you. Some of these dies have to produce thin slots, small holes, or tricky coins.

With the tooling trade in its current challenging economic situation, some tool companies are being forced out of business, losing money, or entering into highly competitive markets.
Many of today's consumer products, commercial and industrial processing machines, and automotive components are being exposed to continually higher temperatures and more severe corrosion.

Since the early days of metal stamping, removing scrap from stamping dies and presses has caused many headaches. Because scrap is not the primary product companies produce, it receives less attention than the finished products coming off the press.
