Ruicheng Precision Machinery primarily specializes in producing ball-expanding plugs. We were among the first in China to engage with ball-expanding plugs and strictly adhere to production standards. Currently, our company boasts over 20 high-precision automation devices, capable of meeting the demands of medium to large-scale customers. In 2017, we obtained the international ISO9001 quality management system certificate. Guided by the principle of 'quality first, reputation first', we continuously learn, innovate, and strive to provide customers with top-notch products and excellent services.

Unlike many of our peers, we place greater emphasis on the safety and reliability of seals, never tolerating any negligence in the production process. We rigorously select materials, employ unique heat treatment techniques, and adhere to domestic and international industry standards in production and processing.
