Quality Assurance Capability

Our company's medical-grade CNC machining has a reasonable and standardized quality control system, which is scientific and rigorous. A strict three-check system is implemented, namely self-inspection by the operator, patrol inspection by the dedicated inspector, and final inspection by the quality department. The company is equipped with coordinate measuring machines, projectors, micrometers, vernier calipers, height gauges, roughness meters, hardness testers, etc. for testing. The critical dimensions CMK are ≥ 1.67. Quality tools such as APQP (Product Quality Pre-Planning), FMEA (Failure Mode Analysis), MSA (Measurement System Analysis), SPC (Statistical Process Control), and PPAP (Production Part Approval Process) are adopted to ensure the stability of part quality. The first-piece inspection → small-batch trial production → mass production process quality tracking.

Compliance Assurance

Sanluo Precision factory strictly follows the standards set by the World Health Organization for medical-grade CNC machining. It can also follow the standards specified by the customers. We strive to learn and understand the regulations of various countries and regions. For example, the regulations of the United States include FDA 21 CFR Part 820 (quality system regulations), 510(k) pre-market notification, and PMA (pre-market approval). The EU medical device regulations, namely MDR 2017/745, CE certification and the preparation of technical documents. In China, there are YY/T0287 medical device quality management system, CFDA registration inspection.
