In special equipment and complex systems, in addition to conventional wire harnesses and connectors, there are many special connection methods, and their sealing performance also directly affects the reliable operation of the system. Whether it is welded connections in high-temperature environments, crimped connections under special working conditions, or precision connections in micro-devices, professional sealing performance verification is required. Hirays provides professional sealing testing solutions for the unique needs of various types of special wire connections to ensure the long-term reliability of the connection system under complex workingconditions.
