1. Incoming material control
For all materials and parts supplied by suppliers, we carry out a series of checks, such as size, strength, hardness, roughness, etc. And we have AQL standard to ensure the accuracy and reliability of finished products.

2. Production flow control
In the assembly line, a series of 100% on-line checks are performed on motor components such as rotors, stators, commutators and rear covers. Operators will conduct self-inspection and quality control through first inspection and shift inspection.

3. Finished product quality control
For the finished product, we also have a series of tests. Routine test includes gear groove torque test, temperature adaptability test, service life test, noise test and so on. At the same time, we also use the motor performance tester to score the motor performance to improve the quality.

4. Shipment control
Our products, including samples and finished products, will be professionally packaged and sent to our customers after production is completed. In the warehouse, we have a sound management system to ensure that the product shipment record is in order.
