A sports watch is a must-have prop for outdoor enthusiasts. Sports watches are different from ordinary watches and are generally waterproof, shockproof, and drop-proof.For sports watches with waterproofing, 3ATM waterproof watches are the most basic starting point for waterproofing.The so-called 3ATM waterproof watch refers to a waterproof watch that can withstand 3 atmospheres of pressure.

The waterproof testing product that Hirays is going to make this time is 3ATM for sports watches.Waterproof test。

As can be seen from the appearance of the test product, this sports watch does not have an inflation port.For products without an inflation port, they cannot be tested by directly inflating them. Waterproof testing needs to be done by making a mold for the test product.This detection method is called indirect testing method.The picture below shows the mold we made based on the shape of the sports watch.

Because the customer's waterproof requirement for the watch is 3ATM, 3ATM is equivalent to the pressure of 30 meters underwater.The pressure at a water depth of 30 meters underwater is converted into air pressure of 300kpa. According to this requirement, the test pressure of this outdoor watch is 300kpa, and the upper limit of leakage is 0.1kpa. The upper limit of leakage is determined by the product and must be obtained by testing the actual leakage of the product.The air intake time is 5s. Because the test pressure is particularly large, it takes a long time for the pressure to stabilize. The pressure stabilization time is set to 15s. The test time is 5s.

The air tightness testing process of the Hirays air tightness detector (also known as waterproof testing equipment) is divided into three stages: inflation-stabilization-testing.Set the corresponding test parameters, and the system automatically performs inflation, voltage stabilization and testing.According to the parameters we set, the system automatically determines the quality of the product and issues an alarm for products that test NG.

Connect the air tightness detector and test tooling together through the factory air source and power supply, enter the corresponding test parameters to start the test.Only required for the operator

Our instruments can be used with simple training, and the operation process is easy to learn.

Hiraysi intelligent sealing tester is a new type of high-precision non-destructive testing equipment.It mainly uses compressed air as the medium to apply a certain pressure to the inner cavity or surface of the product to be tested, and then uses a highly sensitive sensor to detect changes in pressure to determine the tightness of the product to be tested.Because it uses compressed air as the medium, there is no secondary pollution to the product. At the same time, the detection speed and accuracy are better than water detection (air molecules are smaller than water molecules and the leakage speed is fast), so it can be implemented on a large scale in production lines.

For waterproof watches, Hirays Technology has tested watches with different waterproof levels.There are mainly 3ATM watch waterproof testing and 5ATM watch waterproof testing.
