The foam slush molding apparatus of this invention comprises a mold and a hot air jacket, and an optional heat retaining hood. The hot air jacket and the optional heat retaining hood are provided along and a certain distance apart from the molding surface on which a resin is heated and fused. The molding surface and the jacket form a first hot air chamber for heating, and the jacket and the optional heat retaining hood form an optional second hot air chamber for heat retention. The apparatus permits uniform heating and foaming at an efficient molding cycle.
