They accurately produce products of various shapes such as connecting pins and flat cables and meet diversified needs of customers.

Shaped Wire Drawing Dies
Features

Wire material having better surface luster and higher dimensional accuracy can be obtained in comparison with the wire rolling method, a method of manufacturing wire materials of various cross sections. These dies can be used for a wide range of cross sections in addition to square shapes.

Application

Copper wires such as flat cable, connecting pins for OA equipment, decorative articles such as necklaces, copper wires for automotive alternators, small motors, actuators and voice coil motors.
