Centered on core principles including "customer focus, continuous improvement, and fact-based decision-making", the ISO 9001 Quality Management System establishes a full-process quality control framework for hydraulic enterprises. Starting from the raw material procurement stage of hydraulic components (such as pumps, valves, and cylinders), the certification system requires enterprises to establish a rigorous supplier access and evaluation mechanism, and conduct physical and chemical performance testing on key raw materials like steel and seals to ensure controllable quality at the source. During the manufacturing process, standardized operating procedures (SOPs) are adopted to regulate processing accuracy, assembly techniques, and cleanliness control. For instance, CNC precision machining technology is applied to the hole machining of hydraulic valve blocks, and pressure testing, tightness testing, and other procedures are implemented to eliminate common quality issues such as internal leakage and external leakage. Before product delivery, in accordance with ISO 9001 requirements, comprehensive performance testing is conducted, including flow testing under rated pressure, oil temperature adaptability testing, and life fatigue testing, to ensure that each hydraulic device and each set of hydraulic systems meet the customer's technical requirements and industry standards.
