The technology of wine bottle is usually made of glass by hot melt casting. It has the advantages of high density and strong sealing. Its waterproof or not is directly related to its shelf life. Therefore, in the process of production and filling, manufacturers have to test the water resistance of wine bottles. Harris technology has been doing a lot of research in the field of water resistance testing. This time, we will share the waterproof test cases of Jinjiu bottles, hoping to give you a reference.
Water proof tester for strong wine bottle
1、 The shape of Jinjiu bottle and the display of test difficulties
1. The shape of the wine bottle is made of glass with high density. The overall shape is irregular. The head is the butt joint of the bottle cap, and the butt joint of the bottle cap is fine;
Strong wine bottle
2. The shape of Jinjiu bottle is more precise, so it is impossible to use direct detection method to fill gas into the bottle, which is unfavorable to the accuracy of detection results.
2、 Breakthrough of waterproof test difficulty of Jinjiu bottle
1. The overall structure of the toasting bottle has a high degree of precision. Harris technology has specially customized a mold for the bottle. The whole mold is nailed according to the length, width and height of the bottle. When testing, as long as the bottle is put into the groove, the whole shape is just right;

2. Put the strong wine bottle into the tooling mold and connect it with our instrument. There is a valve island, gas tank and other parts inside the instrument and the program we set. After connecting, press the start button when testing the wire. When testing, the upper and lower molds will be closed. At the beginning of testing, the upper and lower molds will be closed, and the instrument will fill the upper mold with impurity free gas, so that the waterproof condition of the opposite wine bottle can be judged by the air saturation inside the mold;
Waterproof test process of strong wine bottle
3. If the bottle of strong wine is not sealed and air leakage occurs, the leakage value in the instrument will be larger and larger, and the pressure value will drop. At this time, it can determine whether the bottle of strong wine is leaking, and the instrument test results will also show ng, which means that the air tightness test fails. If there is no air leakage in the tested strong wine bottle, the gas in the tooling mould will be in a constant state after inflation, the pressure value and leakage value displayed on the instrument are also stable, and the test result of the instrument will display the word OK, indicating that the waterproof test has passed.
