TUBE FOR FIXING AND PROCESS FOR PRODUCING THE SAME

Document Type and Number:

WIPO Patent Application WO/2007/142312

Kind Code:

A1

Abstract:

A tube for fixing that is improved in durability; and a process for producing the same. Bottomed prime tube (1) of a metal with plastic capability while rotating the same around its axial line is subjected to spinning machining for reducing the thickness (A) of side wall thereof to a thickness of 20 to 50 μm to thereby obtain metal original form (4). The metal original form (4) after the spinning machining is segmentalized into metal tube (6). The surface (6a) of the metal tube (6) is sandblasted to thereby attain impartings of residual compression stress and surface roughening. The sandblasted surface is furnished with fluororesin coating (7), and the fluororesin coating (7) is heated to thereby induce thermal shrinkage thereof. Thus, the fluororesin coating (7) is shaped into the metal tube (6), thereby obtaining tube for fixing (8).
