With major technology shifts in how stamping presses are fed, stampers are now able to realize increased processing speeds, improved processing flexibility, better quality, reliability and easier setup. The advancements in press feed technology include space-saving line configurations, pilot release, transfer/progressive operations and scratch-free processing, i.e., can gently handle prepainted coil. Even with these advancements,
Pure copper is very ductile, which means it has a high elongation. Pure copper can be annealed at 12,000 to 15,000 PSI yield strength, and when reduced or cold worked substantially, can go to 45,000 PSI yield strength. Copper at elevated temperatures can be 6,000 to 15,000 PSI yield strength. Pure copper can be made
AC variable frequency drives vary in horsepower from 1 to 10,000. AC variable frequency drives are energy efficient. They only use the amount of electrical energy required for the job. In rolling mills, it is very common to use a fraction of the horsepower that is available. By having an energy efficient AC variable frequency
Cluster mills can be 10-high, 14-high, or 18-high. In all cases, cluster mills are designed to reduce stainless or high carbon, high strength alloy steels, or any material when reducing increases the yield strength. Cluster mills have the advantage of running very light gauges under precision tolerances. As an example, a Cauffiel 18-high rolling mill
