Quality

The inherited technique on the production line helps maintain a high standard of quality. We are continuously striving to improve both our technologies and equipment. At the same time, we intend to institute a quality guarantee system that our customers will readily accept. The finished tools will go through rigorous inspection. And they are 100% inspected, whether it be 10 pieces or 500 pieces. No spot check on our final inspection.
