PURPOSE:To fix a preform preset within a cavity of a mold to the mold without interposing thermoplastic resin and injection-mold a molded product having more higher quality, in a SRIM (structural and reactive injection molding method). CONSTITUTION:A preform body 26 which is comprised of a reinforced fiber 25 and possesses magnetic properties or is obtained by adding the magnetic properties is arranged within a cavity 22 beforehand prior to injection of a mixed solution. After fixing of the preform to molds 20, 21 by the magnetic field from a magnetic substance 23 fitted to the molds 20, 21 or outer region of the molds 20, 21, the mixed solution is injected within the cavity 22. |
