Material control starts before production. Metal materials are selected according to product structure, machining requirements, and application standards. For conductive parts, suitable high-conductivity copper materials are used where required.
Before materials enter production, they are checked against confirmed technical requirements and internal production standards. Only materials that meet the required specification are released to the next step.

Production starts from raw materials and continues through in-house machining and assembly. This allows tighter control over key dimensions, product structure, and fitting condition throughout the manufacturing process.
Each step follows confirmed drawings, process requirements, and internal standards. For key fitting positions and assembly-related areas, the focus is on dimensional accuracy, correct assembly position, and stable batch-to-batch control.
Inspection runs through machining, assembly, and final packing. Checking focuses on key dimensions, fitting condition, assembly position, product appearance, model information, and order accuracy.
Before shipment, every order goes through 100% pre-shipment inspection. Quantity, labels, packing condition, and product confirmation are checked before delivery to reduce model errors, packing mistakes, and shipment inconsistencies.
