    Abstract: Seed holes (h) are formed by discharging a pressure medium (G) in a resin body (R) injected in a cavity (4) of a die (MS1). By expanding the cavity (4), supplying the pressure medium (G) to the seed holes (h), a size of the resin body (R) is increased, making the seed holes grow, to have a molded resin plate (Vr1) made of the resin body increased in the size and formed with the seed holes grown to internal voids (Vd).

    Abstract: A plastic window panel for an automotive vehicle comprises a plastic panel of a transparent noncrystalline organic high polymer. Silica particulate is dispersed in the plastic panel and has a particle size not larger than wavelengths of visible light. The plastic window panel is produced by one of a first method and a second method. The first method comprises (a) providing a first solvent in which the silica particulate having the particle size not larger than wavelengths of visible light is dispersed, and a second solvent in which the transparent noncrystalline organic high polymer is dissolved; (b) mixing the first solvent and the second solvent to obtain a resin composition; and (c) molding the resin composition under heating. The second method comprises (a) providing the silica particulate having the particle size not larger than wavelengths of visible light; (b) mixing the silica particulate into the organic high polymer which is in a process of formation of the organic high polymer, to obtain a resin composition; and (c) molding the resin composition under heating.
