However, the water expansion process has the defects in the preparation of the special-shaped kettle:

(1) the water injection core rod suitable for the special-shaped kettle is complex to manufacture, and the inner wall is easy to form scratches in the process that the water injection core rod extends into the kettle blank;

(2) the water expansion die with the port for sealing water is adopted in the conventional kettle, namely the shapes of the sealing element and the kettle port are kept consistent, so that the sealing element is attached to the kettle blank port, and the water sealing effect is achieved. But for the irregular kettle with an irregular port, the sealing is difficult, and the main reason is that the conventional water sealing piece is difficult to be attached to the shape of the port of the irregular kettle blank, so that the requirement on the shape of the water sealing tendon is very high, and the water sealing effect is difficult to ensure.

(3) In addition, as for the water expansion die with the water sealed port, after the water sealed beef tendon reaches a fracture fatigue state after being used for a period of time, tiny chips are generated and are brought into the water expansion cavity by high-pressure water flow, so that concave points are formed on the inner wall of the kettle blank.

Therefore, the water expansion mold for the conventional kettle is difficult to adapt to the water expansion mold for the special-shaped kettle, and is used for improvement.
