Through process iteration on the production line, the comprehensive yield rate of the main continuous mold production line of Tebang Precision Stamping has steadily increased to * * 98.5% * *, and the average mold life has increased by about 20% compared to the previous generation. By optimizing material utilization (the industry average loss rate has decreased from 8% in 2020 to 5.5% in 2025 [^ 6]) and deploying online testing, the unit cost of stamping has been further reduced.

This upgrade mainly covers high-frequency precision components such as electronic shielding covers, connector terminals, and chassis mounting brackets, with tolerances that can be stably controlled at the ± 0.05mm level, meeting the strict consistency requirements of equipment manufacturers.
