56 ABSTRACT In accordance with the present invention, there are provided processes for molding saturated crystalline polyester resins into a desired shape by supplying said resins to a molding machine, which processes are characterized in that the starting saturated crystalline polyester resin is heated in the molding machine to a temperature above its melting point and allowed to reach in a substantially molten state to a compression section of the molding machine, thereby molding the melted starting resin into the desired shape, or the starting saturated crystalline polyester resin is heated to a temperature above its melting point to bring to a substantially molten state and supplied to the molding machine, thereby molding the molten starting resin into the desired shape, and that the crystallizing temperature Tc2 of the molded article obtained thereby and the crystallizing temperature Tc1 satisfy the relationship of Tc1 - 20 ? Tc2 ? Tc1, and also molding equipments for saturated crystalline polyester resins employed therefor.
