Document Type and Number:

WIPO Patent Application WO/2005/090645

Kind Code:

A1

Abstract:

The invention provides a method of producing an electrocast tube having a fine inner diameter, and an electrocast tube. It also provides a thin wire material for production of an electrocast tube having a fine inner diameter. An electrocast tube producing method comprising the steps of forming an elecrtodeposit around a thin wire material (30) by electrocasting, and removing the thin wire material (30) from the electrodeposit, wherein the thin wire material (30) is removed either by heating the electrodeposit for thermal expansion or by cooling the thin wire material (30) for contraction, so as to form a clearance between the electrodeposit and the thin wire material (30), followed by gripping and pulling, or sucking the thin wire material (30) or physically pushing it away or blowing gas or liquid to push it away.
