The Quality Inspection and Quality Management Departments ensure compliance with these standards, adopting a "one-vote veto" system where components that do not meet the "Quality Specification" are neither inspected nor used in production. All products undergo a rigorous testing process after leaving the production line. They are subjected to a 72-hour full-load aging test at an ambient temperature of 45°C and are individually tested in accordance with GB7260-87 and GB/T2859.1-1993 standards. Specific test items are detailed in the inspection report. Due to the advanced design of our products and the comprehensive quality management implemented within the company, our products are highly reliable, have a long service life, and are delivered quickly. We offer a two-year warranty, promising to replace any product with non-human-induced quality issues with a new one.
