Abstract:
1. A molding method for manufacturing a resin molding by charging a resin composition comprising fibrous filler (A) and crystalline resin (B) in molten state into a die by injection, the resin composition comprising not less than 7 wt % to less than 30 wt % of the fibrous filler (A) and more than 70 wt % to not exceeding 93 wt % of the crystalline resin (B), the method comprising: charging the resin composition in a molten state into the die when a temperature of the die is in a range of Vicat softening point −20° C. to less than a melting point of the resin (B), thereby shaping the resin composition, after the resin composition is shaped, holding the temperature of the die for a predetermined time in a temperature range from a crystallization temperature −10° C. to the crystallization temperature +10° C. of the crystalline resin (B), and cooling down the die to a temperature which allows taking-out of a molded product.
