This video demonstrates the crucial quality inspection process in cable production. Experienced quality control workers are conducting meticulous visual examinations of finished cables at the end of the assembly line. Operators skillfully rotate the cables with both hands, using adequate lighting to carefully inspect the insulation jacket from different angles for scratches, dents, or deformations. They pay special attention to the injection molding quality at connector interfaces, checking whether metal terminals are properly aligned and secured, while using their fingers to gently feel the surface for any abnormal protrusions. This traditional yet effective inspection method combines the acute observation of human eyes with tactile feedback, allowing timely detection of subtle defects that automated equipment might miss. Each cable that passes inspection receives a quality approval label, ensuring that all products meet the highest quality standards before leaving the factory. This reflects the manufacturer's strict quality control and uncompromising commitment to craftsmanship.
