In the field of precision instruments, the quality of watches is crucial.The air-tightness of the entire watch is one of the key indicators to measure its quality.
There are strict and precise testing requirements for the complete watch to be tested.The test pressure is set at 300kPa, with metered air intake taking only 3 seconds, followed by a 10-second inflation process, followed by a 10-second stabilization time.This was followed by a test time of 5 seconds and a deflation time of 3 seconds, for a total test duration of 31 seconds.Every time node has been carefully designed to ensure the efficiency and accuracy of the detection process.
In terms of detection methods, a combination of large leak determination and finished product testing is used, along with customized molds and testing platforms.The customized mold can perfectly fit the shape of the watch and provide stable support for testing; the testing platform ensures the consistency and reliability of the testing environment.In this way, the air-tightness performance of the entire watch can be comprehensively and accurately tested.
The instruments used for the test are HC high-precision differential pressure air tightness detector and supporting test platform.With its high-precision measurement capabilities and stable performance, this detector provides strong technical support for the air-tightness detection of the entire watch.
More importantly, the complete watch to be tested will be judged as a qualified product only when the leakage value specified during the testing process does not exceed 100Pa.This strict standard ensures that only watches with excellent air-tightness can enter the market, providing consumers with reliable time measurement tools.
In short, through strict testing of the air-tightness performance of the entire watch, from the fine setting of testing requirements to the scientific selection of testing methods, to the use of advanced instruments, every link demonstrates the persistent pursuit of quality.This not only sets a quality benchmark for the watch industry, but also provides useful reference for the testing of other precision instruments.
