In industrial manufacturing, product reliability and safety are critical. To ensure product quality, both air tightness testing and air pressure testing are essential, but they serve different purposes.
Air tightness testing, as the name implies, evaluates whether a product can maintain a seal when pressurized, ensuring waterproof performance. Products such as electric toothbrushes and mobile phones need to prevent moisture intrusion to function properly. During the test, the product is pressurized, and the pressure change over time is monitored to detect any leakage. For custom sealing fixtures, test adapters, or connection components used in these tests, Hansheng Automation provides precision machining services based on customer drawings and specified tolerances, helping achieve stable and repeatable sealing conditions.
Air pressure testing, on the other hand, evaluates a product's ability to withstand pressure. By applying gas pressure higher than normal working pressure, the test checks whether the product maintains structural integrity and strength under high pressure. For example, new energy batteries undergo air pressure testing during the design stage to ensure they do not rupture under high pressure. For non-standard high-pressure test chambers, reinforced connectors, or custom pressure-resistant components used in these tests, Hansheng Automation can machine parts according to customer specifications, supporting reliable high-pressure testing setups.
Which products require air tightness testing? Almost all products with high sealing requirements need this test, including home appliances, automotive components, medical devices, and electronic products such as mobile phones and tablets. These products must ensure no internal air leakage to avoid performance or safety issues.
Air pressure testing is mainly applied to equipment that withstands high pressure. In aerospace, pipeline equipment, pressure vessels, and new energy batteries, products face significant pressure during actual use, so air pressure testing is necessary to ensure sufficient mechanical strength.
