METAL FERRULE AND METHOD OF PRODUCING THE SAME

Document Type and Number:

WIPO Patent Application WO/2001/048270

Kind Code:

A1

Abstract:

A dimensionally accurate small-sized metal ferrule and a method of producing the same, wherein the energy cost is low and an expensive molding machine or mold is not required. A metal ferrule having an inner diameter of 0.125 - 0.130 mm and an outer diameter of 2.0 - 3.0 mm. Further, a metal ferrule having an inner diameter of 0.125 - 0.130 mm and an outer diameter of 0.25 - 1.25 mm, and a small-sized metal ferrule having an inner diameter of 0.126 - 0.128 mm and an outer diameter of 0.25 - 0.9 mm. The metal ferrules are produced by forming a metal film on the outer surface of a metal core wire of minute outer diameter by electrocasting to form a metal column of predetermined outer diameter, cutting the metal column into predetermined lengths to provide columnar blocks, thrusting a jig into the core wire end surface portion in one end surface of such columnar block to project the core wire out of the other end surface of the columnar block, and pulling out the core wire by gripping the projected core wire portion.
