The invention provides a method for manufacturing a buoy and the buoy manufactured through the method. The method for manufacturing the buoy comprises the following steps that A, elastic foam materials are put in a lower mold uniformly, and an upper mold and the lower mold are closed; B, the upper mold and the lower mold are heated to raise the temperature in the molds; C, the upper mold and the lower mold are loosened, and the upper mold is lifted, so that the elastic foam materials in the upper mold and the lower mold are expanded to be formed into a semi-finished buoy; and D, the semi-finished buoy is trimmed, and the finished buoy is obtained. The solid buoy formed through one-time foaming and manufactured through the method is resistant to acid and alkali, anti-aging, high in elasticity, good in comfort and high in reliability; the method for manufacturing the buoy is simple and ingenious; the foaming quality is improved, the buoy with two colors can be manufactured, and the attractiveness of the buoy is improved.
