Equipment used: Hirays’ HC Classic Series Air Leak Tester
Solution: using indirectly test function, the INPUT PRESS is 15Kpa, the Filling time is 5s, the stable time is 8s, the testing time is 5s .During the test, if the leak does not exceed 50pa, the product is qualified.
According to the projector lamp design test mold, put the test product on the mold, start the equipment, the upper mold and the upper mold close sealing product, the testing start, through the process of inflation, pressure stabilization, testing and other processes to monitor the pressure change of the internal air pressure of the mold.
