Our factory upholds the principle of "Quality from the Source." 

All raw materials pass rigorous multi-stage inspections before being approved for production. 

The assembly line utilizes dual-positioning jigs to guarantee error-free component insertion. 

Semi-finished units undergo individual voltage stability tests, while final products endure 4-hour extreme environment aging. 

QC teams perform full inspections on every batch for appearance, functionality, and durability, followed by laser-engraved certification marks. 

With 12 critical checkpoints from raw materials to finished goods, we deliver precision-engineered quality at every step.
