  • Publication number: 20090195934
    Abstract: A spring member manufacturing device that manufactures the spring member by laser irradiation includes a laser irradiation unit including a plurality of laser irradiation devices that perform predetermined laser irradiation with respect to the spring member. In the spring member manufacturing device, the laser irradiation devices are configured so that laser irradiated conditions different from each other are preset for the respective laser irradiation devices, and are arranged so that the respective irradiated positions do not overlap each other. The laser irradiation apparatus is constituted by combining laser irradiation devices having laser irradiation conditions being 2 to the (n?1)th power, n being a positive integer,of predetermined minimum adjustment amount for adjusting load on the spring member. The combination of the laser irradiation devices are selected in accordance with load adjusting amount required for the spring member.

  • Publication number: 20080012185
    Abstract: Light is irradiated to a light curing resin material within a mold. The light penetrates through the light curing resin material at a position off a mask. The light curing resin material gets cured at the position off the mask. The mold in this manner serves to form the contour of a molded product. On the other hand, the mask partly blocks the light. An uncured section is established in the light curing resin material behind the mask. When the light curing resin material is removed from the uncured section, the uncured section provides a hole, for example. If the mask is finely formed, it is possible to form a fine hole in an easier manner in a shorter time. It is possible to realize the mass production of a molded product having a fine hole.
