As the most important part of the watch, the watch movement usually undergoes some modifications to the overall movement of the watch.Waterproof test, the following is a detailed picture of the waterproof test carried out by Hirays on the head of the customer's watch: 

The mold designed by Hirays for customers is a two-in-one mold that can test two watch heads at the same time, speeding up the factory's waterproof testing efficiency and saving equipment expenses for the factory.Because the customer's watch machine head is a complete machine without any place for air intake, we designed this mold for the customer to completely seal the test product and test it by filling the mold with compressed air.Sealing performance of watch head, this detection method is an indirect testing method.

The waterproof testing medium used in the watch head is compressed air. As a testing medium that simulates water, compressed air has smaller molecules and is a non-destructive test.

Our testing process is divided into three steps: air intake stage-Stabilization stage-testing phase.According to the waterproof level of the product and the size of the customer's product.The parameter settings of test time and test pressure are as follows:

Air intake time:5S

Stabilization time:5S

Test time:5S

Test pressure:30KPA

Leak limit:0.05KPA  

This test parameter is set according to the test situation of the product and cannot be universal. If your product also needs to be tested for waterproofing, please feel free to consult us.Hirays Technology。
