In this method, a preform is firstly formed, a preform is heated, a preform is biaxially stretched in a mold, a stretched bottle is held in a mold, and a hot air of 160-240 DEG C is blown into the inner cavity of the bottle and heated for 0.5-5 seconds. , Blow in cold air below 100°C. When the bottle is cooled below 100°C, open the mold and take the bottle. The hot air pressure is 0.5～4.0Mpa, the air pressure is 2.5～3.0Mpa, and the mold temperature is 60～100°C. By using this method, the polyester bottle can obtain the best crystallization and setting effect, the heat resistance of the polyester bottle can be improved, the hot filling temperature of the PET bottle can be increased to 115° C., and the sticking phenomenon does not occur, and the production efficiency is improved. ,reduce manufacturing cost. Sovereignty Item 1. A method for manufacturing a high-temperature-resistant polyester bottle. First, a preform is produced, a preform is heated, and a preform is biaxially stretched in a mold. The feature is that the biaxially stretched bottle is kept in the mold. The bottle is blown into the hot air at 160-240°C and heated for 0.5-5 seconds. Then, cool air below 100°C is blown into the bottle, and the bottle is opened after the bottle is cooled to below 100°C.
