Automotive Interior And Exterior Trim Parts

Automotive Interior and Exterior Trim Parts

Introduction to Laboratory

As an important part of automotive products, automotive interior and exterior trim parts directly affect the usability, functionality and safety of complete vehicle. Under the increasingly strict requirements of consumers and the background of green manufacturing, consumers are increasingly demanding on the quality of automotive interior and exterior trim parts. The performance test of the interior and exterior trim parts is indispensable for both the traditional fuel vehicles and new energy vehicles.

CVC has been deeply involved in the automotive industry for more than 20 years, and can provide a complete range of testing services for the automotive interior and exterior trim parts with abundant testing experiences and data. CVC has been approved by many automakers such as General Motors, Ford, Dongfeng Nissan, GAC Toyota, GAC Honda, Shenlong Motors, GAC, SAIC, Dongfeng, BYD, Weltmeister, Lixiang, HOZON, etc. The laboratory has more than 20 years of testing experience and data in terms of artificial accelerated aging and natural climate aging, and has a doctoral team specializing in failure analysis of automotive interior and exterior trim parts.
