Impact of ambient temperature on the perceived quality consistency of automotive interior and exterior trim components

Currently, automotive manufacturers highly prioritize the perceived quality of vehicles, with dimensional engineering being a key influencing factor. Automotive interior and exterior trim components undergo slight deformation due to temperature changes, affecting fit dimensions and imposing stricter consistency requirements. This paper examines the deformation mechanisms of typical parts under varying temperatures using dimensional engineering techniques to study the impact on component gaps. Testing quantifies changes in gap width and surface flatness during temperature variations, providing a theoretical basis for design. The research offers practical guidance for identifying potential issues early in product development and ensuring effective collaboration in production, helping companies achieve higher standards and superior quality.
