Its documented production includes two lines and annual capacities of 100,000 sets each for mortise locks and mortise lock bodies, plus 50,000 door locks. The supplier reports ISO 9001 certification, while many products reportedly hold CCC and CE certifications.

These statements provide explicit evidence of management-system certification and product certifications, although the records do not identify the specific certified models or certificate validity dates.

It also reports six to ten years of total R&D engineer experience and identifies innovation as part of its development strategy, supporting a positive indication of technical and innovation capability.
