In extruder drives, the ratio of net power requirement to installed power is very small, a condition known as a power "mismatch." Depending on cable type, cable/conductor diameter, insulation thickness, line speed, and pulling force, cable manufacturers have until now been forced to pay a lot of money for unnecessary power consumption every year. This paper discusses opportunities to make incremental improvements in extrusion lines that deliver significant cost savings. In particular, it discusses a new (and patented) drive technology.
