We talk a lot about the new reality for coil coaters. Their customers are demanding smaller lot sizes and more frequent shipments. Often they are asking for delivery of just a portion of a coil!
This has driven coil coating runtimes down proportionately. The average coating system run is now less than one hour. In turn, this translates into 1–2 color changes per hour. And if you do the math on that, it extends out to more than 30 color changes per day!
