COOLING METHOD AND COOLING DEVICE OF MOLDED RESIN PRODUCTS
20210107186 · 2021-04-15 · ·

The present invention relates to a cooling method and a cooling device of molded resin products which are made from a synthetic resin as a raw material and are ejected from a press molding apparatus. An object of the present invention is to shorten a molding time and ensure product quality. A molded resin product M which is ejected from a die in a still hot state is supplied on plural jigs 30 on a rotational stage 26 in a cooling chamber 24 from an inlet 34. Dry mist F is sprayed from nozzles 60 of spraying units disposed at upper portions of the cooling chamber 24 to the molded resin product M. The dry mist F sprayed from the nozzles 60 to the molded resin product M is vaporized under a heat amount in which the molded resin product M has. Thereby, the heat is removed from the molded resin product M, and the cooled molded resin product M is ejected from the outlet 38 without adhesion of a water droplet. The dry mist is sprayed in a state that the cooling chamber 24 is closed. The molded resin product M during cooling is mounted on the jig 30 for preventing deformation due to gravity.

Method of producing a metal form containing dispersed aerogel particles impregnated with polymers
10981216 · 2021-04-20 · ·

A method of producing a metal form containing dispersed aerogel particles impregnated with polymers comprising a method of impregnating an aerogel with polymers, placing the aerogel impregnated with polymers within a dissolved polymer, cooling the dissolved polymer to create a polymer form with dispersed aerogel particles impregnated with polymers, adding molten metal to the polymer form, vaporizing the polymer form, replacing the polymer form with molten metal, and cooling the molten metal to yield a metal form containing dispersed aerogel particles impregnated with polymers. Dispersing the aerogel particles impregnated with polymers within the polymer form prior to adding molten metal allows the aerogel particles to be fully dispersed throughout the metal form.
