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.

Because of sluggish economies and uncertain markets, the need to hone a competitive edge is more sharply defined. Many stampers are doing this by taking control of their material inventory and production schedules by adding a cut-to-length blank shearing line.An in-house blank shearing line...

Bend angles are among the most frustrating geometric features to control in metal stamping. This is due primarily to two factors – the inconsistency of the mechanical properties in the metal being bent and the die design.

All businesses tied to the metal forming industry are scrambling to find areas in which they can lower costs without sacrificing quality. Adding to this burden are a tight cash flow and a lack of financial resources to invest in process improvement equipment. Therefore, the savings must come from doing more with less.

To promote real-world stamping training, the Tooling & Manufacturing Association (TMA) wanted to create a resource whereby stampers could receive a consistent, recognized, hands-on education on the industry's most current equipment.

The most disruptive type of failure in any tooling application is when the tool cracks. To prevent this type of failure in cold-work applications, it's important to select the correct steel.

As manufacturers worldwide strive to reduce costs and streamline their production processes, the market for surface-sensitive materials continues to expand. Surface-sensitive materials include all prepainted steel products and nonferrous decorative materials, such as copper, brass, and stainless steel.

Stretching or embossing, not to be confused with drawing, is the process in which the part's geometry is obtained by stretching the metal into a forming cavity.

It is not unusual for me to perform a few magic tricks when holding a conference on stamping die drawing, troubleshooting, or processing. Later on, I may disclose the magicbehind the trick. I do this for a couple of reasons: first, to entertain the conference attendees, and second, to show them that there is no such thing as magic, only physics.

Sheet metal manufacturers are under constant pressure to improve and document quality while reducing costs. Furthermore, original equipment manufacturers are shifting responsibility for quality inspections to suppliers, adding extra burdens. New, complex product designs and rigorous processes, such as deep drawing and the growing use of exotic materials, are placing greater demands on both quality assurance and development departments.

Mechanical presses are challenged to provide high-speed production with a greater number of hits per minute, smaller batch runs, and quicker die changes.

In this era of global warp speed and virtual reality, calculating the deep draws of progressive dies or the springback of metal is performed by simulation software instead of the earlier trial-and-error method. These software programs essentially replace the artistic methods of diemaking with...
