Today, our test case is the waterproof and breathable film of watchAir tightness testAs can be seen in the figure below, there are many buttons and some ventilation holes on the edge of the middle frame of the watch in the figure. These places are the most easy places for water to enter. If the customer is in a closed or high air pressure place, these holes must be ventilated to keep the internal and external air pressure of the watch stable. Air permeability and waterproof at the same time, which requires our equipment to conduct accurate testing.

Our company will customize a tooling according to the products provided by customers, and then use 300kp air pressure to test, first put the product into the fixture for fixation, and then press the switch to start the test.

The detection principle is to fill the air pressure into the water tank, use the air pressure to the water pressure, and then make it align with the waterproof and breathable film through the blue pipe shown in the figure to complete the detection process; After the test, take out the product to see if there are small water drops on the surface of the reverse water permeable membrane. If there are small water drops, it is ng. If there are no small water drops, then the waterproof permeable membrane is OK.
