Abstract:
PURPOSE: A manufacturing method of a micro type spring is provided to improve the installation stability of the spring and to reduce the manufacturing cost. CONSTITUTION: A photosensitive unit(130) in which the photosensitive solution coagulates in the outer circumference of a wire(110) having the cross section of the predetermined shape is formed. The beam is spirally emitted to the photosensitive unit and is dipped in a developer. A mold(140) in which a groove(132) of helix is formed in the photosensitive unit is made. The mold is put into a predetermined molten metal bath and the molten metal is charged in a groove. The molten metal is solidified and the metal unit is created. The mold is dipped in the photosensitive unit solution and the mold is eliminated. A wire is dipped in the photosensitive solution. The photosensitive solution coagulates in the wire outer circumference by adding the heat to the wire.
