METHOD FOR MANUFACTURING ELECTRIC WIRE

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing electric wire capable of efficiently manufacturing high quality electric wire.

SOLUTION: The method for manufacturing the electric wire includes: a material supply stop process (step S02) for detecting that amount of resin required for coating a wire rod with a remaining length to reach a set length is supplied to an extruder to stop the supply of the resin to the extruder; a linear velocity switching process (step S03) for shifting an operation to a lower limit linear velocity coating operation for coating the wire rod with the resin by setting the linear velocity of the wire rod to a low linear velocity which is slower than a regular linear velocity and equal to or faster than a lower limit linear velocity, after stopping the supply of the resin to the extruder; an outer diameter control response changing process (step S04) for quickening a response speed of outer diameter control of the wire rod according to the extruded flow of the resin from the extruder, after stopping the supply of the resin to the extruder; and an outer diameter control stopping process (step S07) for stopping the outer diameter control at a point when the electric wire is extruded by the set length.
