Abstract Key process parameters in windshield glass forming significantly impact the final product′s quality. There is no systematic study on the sensitivity of morphological deviation to process parameters in windshield glass forming. This paper first analyzed the mechanism behind the morphological deviation of the windshield, providing a theoretical basis for optimizing the forming process. Then, the cooling stage of the forming process was simulated by the finite element method. The effects of the mold expansion coefficient, holding force, annealing temperature, and annealing rate on the morphological deviation were studied. The results show that a smaller difference in the thermal expansion coefficients between the mold and the glass leads to a significant reduction in the morphological deviation of the windshield. During annealing, the application of a hol-ding force reduces the morphological deviation as the force magnitude increases. However, once the glass transitions into its elastic state, excessive holding force may lead to fracture. Annealing performed within the temperature range below the transition point effectively minimizes morphological deviation. Within this range, the specific annealing temperature and cooling rate have a comparatively minor influence on the final deviation.
