Most of the products of the face painting machine do not have any inflatable port, for the face painting machine test products without air vent, there is no way to directly inflate the method of testing (that is to say, if the face painting machine has a breathable hole, you can use the face painting machine airtightness testing equipment to directly carry out the waterproof testing of the face painting machine). Therefore, it is necessary to make a test mold for the product according to the shape of the face painting machine, place the product in the mold, inflate the mold through the airtightness testing equipment of the face painting machine, detect the real-time pressure changes through the precision sensors inside the airtightness testing equipment of the face painting machine, and give the results of the inspection according to the set parameters so as to realize the waterproof testing of the airtightness of the face painting machine. Moreover, the airtightness testing equipment uses compressed air instead of water, because the face painting machine is also a kind of electronic product anyway, and the circuit board will cause problems when it encounters water, therefore, even if the waterproof testing of the face painting machine fails, it will not cause secondary damage to the product due to water ingress.
