IP waterproof testing cost effective and low? Airtightness testing is the best solution

This article introduces IP65, IP66 and IP67 waterproof testing, pointing out that traditional water testing is costly and inefficient, while airtightness testing is low-cost, non-destructive and quantifiable. Precision Industrial Technology's automated test system uses the pressure drop method and differential pressure method to achieve efficient and accurate testing, and improve product quality and market competitiveness.

From soaking to gas testing: 3 minutes to understand the whole process of the technological revolution of the airtightness and waterproofness testing of cell phone cases

This paper describes the change of waterproof testing technology for airtightness of cell phone cases. Traditional water immersion testing has problems such as high cost, low efficiency, rough results and strong subjectivity. Modern airtightness testing equipment uses gas to simulate water pressure and accurately detects leakage through the principle of pressure drop or flow rate, which has the advantages of high precision, non-destructive testing, scientific data management, etc. It brings quality assurance and commercial value to cell phone manufacturers, and it will be developed in the future towards higher precision, faster speed, and more intelligent direction.
