Die castings have excellent mechanical properties and physical properties. They can have various comprehensive properties of strength, hardness, and toughness, and can also have one or more special properties, such as wear resistance, high and low temperature resistance, corrosion resistance, etc. Therefore, power battery casings also tend to use metal casings, but the metal casingswater proofIt's always been a problem.

Products to be tested: Auto parts

Die castings can be manufactured asAuto parts, automotive die castings, motor casings, etc. Die castings are generally relatively precise components and are generally not allowed to leak. This must be determined by air tightness testing equipment.

Product to be tested: motor housing

The traditional detection method, the water immersion method, generally introduces a certain pressure of gas into a closed cavity, sinks the workpiece into the water, and observes whether there are bubbles overflowing.The testing efficiency of this method is not high, the tools are inconvenient to use in the production line, and the test results are manually determined and the standards are not rigorous, which has a greater impact on the results.

Products to be tested: automotive die castings

With the improvement of waterproof detection technology, the current mainstream waterproof detection method is air tightness detection.Hirays air tightness and waterproof testing equipment uses compressed air as the testing medium. Even if the product fails to pass the test, it will notFor secondary damage, everyone knows that air molecules are smaller than water molecules, so the test results will be more accurate.This is also why forThe reason why everyone uses air tightness testers for waterproof testing of precision instruments.
