Stretching metal's forming limits with HSP lubricants
The trend in metal stamping is to use more and more aluminum and other lightweight materials, such as advanced high strength steel (AHSS). The need for technology to help improve metal flow of these materials in deep-drawing applications also is increasing. In many cases, a stamper's original... Read more...

High-speed feeding techniques
The maximum operating speed of a stamping operation should be limited, in theory, only by the maximum number of strokes per minute (SPM) that the press can achieve. In reality, production speed is limited by other factors as well. For instance:
1. The uncoiler may not unwind... Read more...

Radiographic and ultrasonic weld inspection
Radiographic and ultrasonic weld inspection are the two most common nondestructive testing (NDT) methods used to detect discontinuities within the internal structure of welds. The obvious advantage of both of these testing methods is their ability to help establish the weld's internal integrity... Read more...
