The pressure is on
The 400-ton pressure testing setup shows the die components and bumper blocks. The traditional method of measuring pressure distribution in stamping operations—the die spotting blue technique—indicates the pressure points but not how much pressure. This makes it difficult to... Read more...

Using analog technology to errorproof the stamping process
Measuring important part features using analog sensors during the stamping process can reduce the need for time-consuming in-process checks, expensive attribute gages, and costly part-sorting at the press.
A die protection program that prevents mis-hits and die crashes and prevents unplanned... Read more...

Sensors clear the way for high-speed stamping
Tennessee Stampings (Portland) LLC stamps 100 million ride control components (struts and shocks) annually. To sustain high-speed stamping, the company puts sensors on all of its dies to prevent collisions and the production of defective parts that would bring its presses to a screeching... Read more...

Where sensors make sense
Sensor-driven errorproofing can help stamping shops prevent the production of bad parts, die crashes, and downtime. Metal formers today find that increasingly customers are no longer satisfied with just a low percentage of defective parts, measured in parts per thousand. Today customers... Read more...

Coming to your sensors
The most difficult aspect of implementing a stamping sensor program is figuring out where to place the sensor. For example, in this application, two stamping sensors on opposing ends of the die face each other and communicate across an air gap that runs the length of the die. (Photos and... Read more...

Error-free tube fabrication
In addition to detecting the weld seam, some modern electronic sensors are sophisticated enough that, when properly programmed, they can differentiate between a good weld and a bad one. Picture the activity in a typical automotive assembly plant. Dozens of synchronous industrial processes... Read more...

Implementing a stamping sensor program—uphill
Stamper and toolmaker Ultra Tool & Manufacturing, Menomonee Falls, Wis. had been installing basic stamping die protection for 15 years. Whisker sensors, positive stops, and, in some cases, part-out sensors comprised the limited sensor system for dies that ran in automatic mode. However,... Read more...

Controlling double sheet in stamping operations
Almost everyone has experienced a double-sheet problem. Copiers, printers, and fax machines sometimes feed two sheets, which then jam the machines and have to be removed.
While two sheets of paper seldom cause major harm to office equipment, two sheets of metal can cause major damage to tools... Read more...
