Abstract

PURPOSE:To obtain resin coating having uniform thickness and high adhesion strength at a high speed by following method in which an inserting bore is expanded at the front end of an inner die having inserting bore for a long bar, and the angle between the expanded part a the bore and an annular discharging port is caused to be an acute angle. CONSTITUTION:A metal die for extrusion with coating has an inner die 1, an outer die 2, a die lip 3 and an annular discharging port 4 etc., and an inserting bore 5 through which a long bar 6 is inserted, is arranged in the inner die 1. The inserting bore 5 is expanded at the front end 12 of the inner die 1, and the angle between the expanded part of the bore 5 and the annular discharging port 4 is caused to be an acute angle. Consequently, the resin film which has been drawn out, can coat the bar 6 with thin coating layer at a high speed, and simultaneously, the adhesion of the resin film which is extruded from the annular discharging port 4 to the die surface, is prevented.
