From the bloom check to tensile or ultrasonic test, Tedrail will take a serious control of the manufacturing to guarantee the quality of axle. 4 How do we guarantee the quality? Experienced Design Engineering After our talented engineers get your drawings, they'll quickly grasp it and point out the key-points. Mature Workshop Directing Mature workshop directing will make sure the manufacturing process precisely control the quality so that the customer's demands will be confirmed. Comprehensive Tests and Inspections Tedrail will carry out comprehensive tests to make sure the quality of Axle. Any test in relevant production procedure must be approved or the axle will be eliminated. Test Category Chemical Analysis Tensile and Impact Test with Mechanical Analysis Micrographic/Microscopic Test Macrographic /Macroscopic Test Ultrasonic Test Magnetic Test Appearance and Dimensions Inspection Serious Quality Assurance After the production is done, our quality assurance team will double-check every axle to guarantee that the axle meet the requirements of clients. |
