We control quality in every production step carefully. The most advanced CAD systems are used to develop updated and better models. Before production, all raw materials must be approved by our QC team under strict inspection. Then we’ll do tolerance check, roundness test, roughness test, clearance check, noise test and vibration test etc. step by step in the process of manufacturing. The test equipments frequently used are: Roundness Test Device, Vibration Measurer, Hardness Tester, Metallographic Microscope and Lifetime Testing Equipment etc. Finally Our QC team will check the markings, exterior quality and packages before shipment.


Besides workshop test, some newly-develop products will be sent to our Automobile Service Garage to take a practical running test on taxies to ensure timely improvements and reliable quality.
To meet customers’ satisfaction, we offer 100 percent quality guarantee: on the one hand, we make sure all products must pass our quality control system before shipment; on the other hand, if any defective products are found by our customers after shipment, we’ll replace the defective products by good products at no cost. All our quality control guidelines are made and implemented in accordance with the management system of ISO9001:2000. We aim to offer products with the best combination of value and performance.
