In this article, we will delve into the intricate details of our quality control procedures at each stage of our production line, highlighting the key elements that contribute to our superior hydraulic rotary actuators.
WEITAI makes the 100% testing for raw materials
At WEITAI, we conduct thorough testing for all our raw materials to ensure their quality and reliability. Every batch of raw materials undergoes comprehensive testing and inspection before they are used in the production of hydraulic rotary actuators. This rigorous testing helps us eliminate any substandard or non-compliant materials, ensuring the highest level of quality in our products.

Safety stock for raw materials. Stock by Special Marks

To maintain a smooth production process/semi-products/seals, we maintain a safety stock of raw materials. This extra inventory acts as a buffer to mitigate supply chain disruptions. We categorize and mark the stock with special identifiers, making it easier to track and manage. This system helps us optimize inventory management, minimize downtime, and ensure efficient production of hydraulic rotary actuators.

Six Axis CNC Milling Center to Ensure high precision of gears and shaft

In our CNC workshop, we utilize a state-of-the-art Six Axis CNC Milling Center to utilizes six axes of motion, allowing for precise movement and positioning of the cutting tools. This level of control ensures that every gear and shaft we produce meets the exact specifications and tolerances required for optimal performance. With the use of this advanced machinery, we can achieve tight tolerances, smooth surface finishes, and excellent dimensional accuracy in the production of gears and shafts. The Six Axis CNC Milling Center enables us to deliver products that exhibit exceptional precision, resulting in improved functionality and reliability in our hydraulic rotary actuators.

CNC parts Dimension Testing and Hardness Testing
Dimension testing involves using precise measuring equipment to verify that the CNC parts meet the specified dimensional requirements. This includes measuring various aspects such as length, diameter, angles, and other critical dimensions. By conducting dimension testing, we ensure that the parts are manufactured within the desired tolerances and meet the design specifications. In addition to dimension testing, we also perform hardness testing on the CNC parts. This test helps us assess the hardness properties of the materials used. By measuring the hardness, we can ensure that the parts have the necessary strength and durability to withstand the operational requirements and environmental conditions they will encounter.

High Precision Welding
We utilize a WELDING ROBOT in our manufacturing process to ensure high precision in welding operations. This advanced robotic system is designed to perform precise and consistent welds on our hydraulic rotary actuators. By employing the WELDING ROBOT, we achieve accurate positioning, controlled heat application, and uniform weld quality, resulting in superior structural integrity and reliability of our products.

Visual Cleanliness Testing
Visual testing for cleaning involves visually inspecting components or surfaces to ensure they are free from visible contaminants or residues. Trained inspectors carefully examine the cleaned parts using appropriate lighting and magnification tools if needed, ensuring that the cleaning process has effectively removed any unwanted substances. This testing helps maintain product integrity and compliance with cleanliness standards, ensuring the quality and reliability of the components.

100% Pressure Testing
WEITAI ensures 100% pressure testing. There are 4 testing platforms in the pressure testing workflow for a full-capacity operation. All actuators should be held 30min with load to test the inner&outer leakage, torque, turning angle, etc.
WEITAI will continue to devote itself to the research and development of hydraulic rotary actuators and will launch power tilt soon. Catch up with the world's top brands like HELAC rotary actuators/HKS actuators. Through our dedication to quality control, advanced manufacturing processes, and continuous improvement, we are confident in our ability to deliver outstanding products that enable our customers to excel in their respective fields.
We value long-term partnerships and collaborative relationships, recognizing that by working together, we can drive innovation, create value, and achieve mutual growth.Forproduct information, please send an email to
