What should be tested for automotive materials?
As the basis of automobile production, the quality of automobile materials and parts is a prerequisite for the success of automobile production. With the increasingly advanced functions of various new models and the continuous pursuit of driving experience and safety, automobile manufacturers are required to monitor the quality and safety of materials at the source.
