摘要： The method comprises the following sequence of stages of operation: feeding the blowing air into the parison enclosed in the mould (1), with the maximum pressure characteristics required for the blow moulding thermoforming cycle, and maintaining this blowing condition for a minimum period depending on the characteristics of the container to be produced; reducing the blowing air pressure to a specified minimum level sufficient to keep the blown container adhering to the inner walls of the mould (1) which contains and shapes it; discharging the blowing air at low pressure from the inside of the blown container, in such a way that the inner surface of the container is bathed by a flow of air which is constantly renewed at the appropriate flow rate, which rapidly reduces the internal temperature of the container, while the external temperature of the container is reduced by contact with the walls of the mould (1) which are cooled by the forced circulation of a cooling fluid; interrupting the blowing cycle and the said cycle for the discharge of the cooling air at low pressure, and appropriately reducing the pressure inside the formed container, in such a way that the container can be discharged from the mould which can be prepared for the execution of a new operating cycle.
摘要翻译：该方法包括以下操作步骤：将吹入空气送入包封在模具（1）中的型坯中，具有吹塑热成型循环所需的最大压力特性，并根据要生产的容器的特点; 将吹送空气压力降低到足以保持吹塑容器粘附到包含并成形它的模具（1）的内壁的规定的最小水平; 从吹出的容器的内部排出低压吹送空气，使得容器的内表面被以适当流量不断更新的空气流沐浴，这迅速降低了内部温度容器通过与冷却流体的强制循环冷却的模具（1）的壁接触来减小容器的外部温度; 中断吹送循环和所述循环以在低压下排放冷却空气，并适当地降低成形容器内部的压力，使得容器可以从可以准备执行的模具中排出一个新的运营周期。
