Quality

      The excellent products stem from our constant pursuit of quality. Protech CV  rigorously implements ISO 9001-2008 quality system and ISO/TS 16949 control system, and strictly carries through quality control and process control. The magnetic particle inspection is applied to 100% joints after the major heat treatment. The inner joint cavity is 100% one-on-one matched with its tripod. The strict quality control of assembly determines the final standard of quality products. In the assembling process, we strictly control the total length of the driving shafts, retractability, fit clearance and the NVH performance of the complete assemblies. The exhaustive standards of OE quality control are implemented throughout the manufacturing process.
