Two-tone car needs to go through the oven twice, PVC and the film on the PVC surface due to shrinkage difference, secondary baking, paint film will produce cracking problem; the interval between two baking times, ambient temperature and humidity, PVC material and film thickness will affect the cracking situation. This paper analyzes several influencing factors through experiments and solves the problem by taking relevant measures.
