[0059] The method has positive pressure inflation: the compressed air provided by the air compressor is adjusted to a predetermined test pressure (such as 5-20Kpa) through a pressure regulating valve, and then the sealed cavity between the test mold and the product is filled with air through an electromagnetic valve. After the inflation setting time ends, the electromagnetic valve is closed for pressure stabilization.

[0060] Pressure stabilization: in the pressure stabilization stage, after the compressed air reaches a stable state, the pressure sensor records the pressure P1 when the pressure stabilization is completed.

[0061] Test: after the pressure stabilization time reaches, the leakage test stage is entered, and the pressure sensor detects and records the pressure change.

[0062] Judgment: according to the pressure change, it is judged whether the product is qualified. If the test pressure P1 is greater than the lower limit of the set inflation pressure and the pressure change value is less than the set upper limit of the leakage, it is determined to be qualified; otherwise, it is unqualified.
