To strictly comply with EMERSON's stringent requirements for material purity, machining precision and sealing performance, we have fully implemented a comprehensive quality control philosophy of "One Process, One Report." From precision ball machining and NDT to micron-level dimensional calibration and final high-pressure leak testing—each manufacturing step is accompanied by corresponding inspection documents and original data records. This establishes a complete quality assurance system that is traceable, verifiable and replicable, ensuring every product's performance parameters fully conform to technical specifications.
We own a systematic and transparent manufacturing and quality assurance system.By virtue of this system, we not only continuously supply EMERSON with ball accessories that are compliant, reliable and highly compatible, but also gain its long-term trust through outstanding product consistency and rigorous process management.Eventually, this cooperation has made us EMERSON’s exclusive supplier in this field.
