The current automotive controllers (die-casting parts) need to reach the IP67 protection level. After taking into account the needs of customers, Hi Ruisi Technology has used the following equipment and solutions for it:
Equipment used: Heruisi HC classic series air tightness testing equipment
Solution: Use direct test method, test pressure 10KPA, inflation time 10S, voltage stabilization time 3S, test time 3S, leakage limit 0.3KPA. Design the test mold and tooling according to the structure of the automobile controller, put the product on the mold as required, start the upper mold and press to block the opening and the top, and the side cylinder pushes sideways to block the side line holes to form a seal inside the product Cavity. The instrument enters the test program to inflate, stabilize, and test the inside of the product, and detect whether the product has leaks by monitoring the change in the internal air pressure of the product. The system automatically determines whether the product is OK or NG according to the set parameters.
