All plastic parts undergo strict quality inspection, including checks on appearance, dimensional accuracy, and material performance to ensure compliance with design specifications and process requirements. Each component must be free from defects and deformation to guarantee proper fit and function in subsequent assembly stages.
Each LED circuit board is thoroughly inspected for soldering quality, component placement, and electrical performance. We ensure all solder joints are secure, with no cold soldering or short circuits, and that all components meet design specifications. This guarantees the stability and reliability of the LED illumination in the final product.
Semi-finished products undergo comprehensive inspection to verify assembly quality, component completeness, and functional performance. Each lighting unit is checked to ensure all parts are correctly installed and operating as intended, in full compliance with quality control standards at each stage of production.
Real-time quality monitoring is conducted directly on the assembly line, with each step of the process carefully checked to identify and correct any issues as they arise. This ensures that every lighting unit maintains high-quality standards throughout the entire assembly process.
Finished exit signs and emergency lightings on the assembly line undergo aging tests that simulate real-world usage conditions. Each unit is operated continuously for a set period to evaluate its stability and reliability. This process ensures long-term performance and minimizes the risk of failure during actual use.
Finished products undergo comprehensive aging and charge-discharge cycle testing to assess long-term performance and battery durability. This ensures that even after repeated charging cycles, the lighting unit maintains stable functionality, meeting the high reliability standards expected of emergency lighting equipment.
Regular random sampling is conducted on inventory to perform charge-discharge cycle testing, ensuring that all stocked products maintain stable performance and healthy battery status during storage. This prevents performance degradation or failure due to prolonged shelf time.
Each product undergoes professional electrical testing, including insulation resistance, dielectric strength (hi-pot), and full functional checks to ensure compliance with national and industry safety standards. These tests guarantee that every unit is safe, reliable, and ready for use.
Acceptance criteria: 100% compliance with export certification standards.
