Title:
MANUFACTURING METHOD FOR WIRE HARNESS
Document Type and Number:
WIPO Patent Application WO/2011/136201
Kind Code:
A1
Abstract:
Disclosed is a manufacturing method for a wire harness having a shape-retaining member and protector comprising a thermoplastic material, said manufacturing method enabling the easy formation of the axial shape of the shape-retaining member and protector into a predetermined shape during manufacture. The manufacturing method has: a first step, in which the periphery of an electrical wire is coated by a body (13) to be molded comprising a thermoplastic material, and in which the body (13) to be molded is formed into a predetermined cross-sectional shape and dimensions by applying pressure thereto while heating the body (13) to be molded at a temperature at which plastic deformation is possible because of the thermoplasticity; and a second step, after the first step, in which the body (13) to be molded is formed into a predetermined axial shape while at the temperature at which plastic deformation is possible because of the thermoplasticity, and is cooled after being formed into the predetermined axial shape. In the second step, the shape-retaining member (12) obtained through the first step is inlaid in a molding section (721) formed in a lower mold (72) of a second molding body (7), forming the axial shape of the shape-retaining member (12), which is then cooled.
