Document Type and Number:
Japanese Patent JP2014208468
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method for producing a resin molding, in which the resin molding having excellent surface gloss is obtained by using a filler-containing specific polycarbonate resin.SOLUTION: The method for producing the resin molding comprises the steps of: using the filler-containing resin obtained by incorporating an inorganic filler in the polycarbonate resin containing, at the least, a dihydroxy compound-derived structural unit having a specific structure; injecting the filler-containing resin into an injection molding metal mold, the surface temperature of whose cavity is made equal to or higher than 60°C; and discharging the resin molding in such a state that the surface temperature of the cavity of the injection molding metal mold is lower than that of the cavity thereof, when the filler-containing resin is injected, by 10°C or more. The time to be taken since the step of injecting the filler-containing resin until the step of discharging the resin molding is controlled to be within 2 hours.
