Originally die protection was developed just to prevent damage to the tool and die during the operation of a stamping press. As sensor and controls technology knowledge has evolved and stampers knowledge of it has expanded, die protection technology has been expanded into other applications, such as increasing production rates and to perform quality assurance.

A Midwestern manufacturer sought to improve productivity on its nearly 10-year-old Verson transfer press. Although the press was in good condition, the original ETF transfer, which had endured 28 million press hits, was causing considerable maintenance costs and lost production. The stamper retrofitted the Verson transfer stamping press with a Schuler Automation AT series tri-axis transfer. This resulted in a 10- to 40-percent improvement in cycle times.

In the home appliance industry, designs are constantly updating to meet consumer tastes and changing market demands. For the stamping supplier forming a new bracket for a new design, high production volumes necessitated tripling the number of shifts. But tripling the number of shifts increased labor costs, as well as utility and material delivery costs. The stamper decreased the labor hours to resume a single-shift operation by implementing quick die change and magnetic die clamping.
