<P>PROBLEM TO BE SOLVED: To provide an effective method for manufacturing an injection molded product which can cool a resin molded product in a high-cycle manner. <P>SOLUTION: A cooling solvent includes at least one of perfluorocarbon, hydrofluorocarbon, hydrofluoroether, and perfluoro ketone. The method uses the cooling solvent which is liquid at normal temperature and which has the following characteristics (a)-(d): (a) the boiling point is lower than 100°C, and the freezing point is equal to or lower than -50°C; (b) steam pressure at 25°C is 5-28 KPa; (c) density at 25°C is equal to or higher than 1,050 kg/m<SP>3</SP>; and (d) surface tension at 25°C is equal to or lower than 20 mN/m. By using such a cooling solvent, the high-cycle cooling can be achieved. <P>COPYRIGHT: (C)2011,JPO&INPIT |
