The wire, now soft and flexible, is passed through an extruder, where either a single or double coating of plastic is applied. High-density polyethylene pellets, colored one of ten industry-standard colors, are fed into the cool rear section of the extruder; as they are pushed forward, they are heated until they melt. Exiting the extruder, the coated wire, now traveling at approximately 60 miles per hour, passes through another cooling trough and is coiled on takeup reels.
