Description

technical field [0001] The invention relates to the field of decorative strip processing, in particular to an automobile decorative strip and a surface treatment method thereof. Background technique [0002] Car trim is a necessary part of every car. It not only plays an aesthetic role but also strengthens the parts. At present, people have higher and higher requirements on the appearance of automobiles, and the processing technology of decorative strips is becoming more and more complicated, so as to achieve better visual effects. Due to the single color, lack of three-dimensional sense and texture, the traditional decorative strips are increasingly unable to meet the requirements of consumers. [0003] In the processing technology of automobile decorative strips, the high-gloss paint has good fullness and high gloss, and the hot stamping process is smooth and smooth with sharp edges and corners. The hot stamping treatment is carried out on the paint surface of the car de...
