Yuethai operates advanced flexible manufacturing lines designed for both high-volume output and tailored production. All hydraulic system components are delivered with a certified cleanliness level of NAS 7, ensuring reliable performance.
To guarantee product quality and consistency, we apply rigorous testing at 100% of critical quality control points, using advanced inspection equipment and processes. Our internal validation procedures are built to exceed industry standards, reinforcing our commitment to quality, reliability, and customer confidence.
Raw Material Area
As a precision hydraulic solutions manufacturer, Yuethai Hydraulics places lifecycle quality consistency at the core of our products. Starting from the source selection, we strictly control raw material quality and conduct rigorous testing on key parameters such as hardness and surface roughness. This ensures the consistency and reliability of base materials, providing a solid foundation for precision manufacturing and long-term stable operation.

Aluminum Alloy
Special-Shaped Castings
Production Area
Leveraging a highly automated and advanced manufacturing system, Yuethai Hydraulics has established a stable and efficient production capacity. Multiple vertical and horizontal machining centers operate in coordinated workflows, enabling high-precision and high-efficiency manufacturing. Among them, vertical 4-axis machining allow one-time forming of complex structures with excellent dimensional accuracy. Combined with intelligent flexible production lines, the horizontal machining centers support continuous production of complex, multi-surface, and high-difficulty components, delivering outstanding consistency and productivity.
In addition, precision equipment, including honing machines, coordinate measuring machines (CMMs), and ultrasonic cleaning systems, is deployed to ensure controlled quality and stable delivery throughout the entire process, from machining to final shipment.

Inspection Area
Yuethai has established a comprehensive quality management system covering raw materials, production processes, and pre-delivery inspection. Multiple performance tests—including pressure drop, response behavior, pressure characteristics, and proportional control performance—are conducted. These tests are combined with validation under extreme operating conditions, such as service life evaluation, high-pressure resistance, and high-temperature endurance, forming a closed-loop, multi-dimensional quality inspection system. This ensures long-term reliability and stable performance of products during operation.
