Abstract
En 中文
Precision injection-molded plastic optical lenses are extensively utilized in imaging optical systems. Surface deviations produced during the injection molding of plastic optical lenses will immediately result in imaging quality issues. Conventional injection molding often employs an orthogonal experimental procedure to validate the chosen process parameter combination post- molding, necessitating substantial raw materials and time for numerous processes. Therefore, this article proposes a multi section method based on warpage and shrinkage behavior for deformation analysis of optical plastic lens precision injection molding. The deformation of precision injection-molded aspherical plastic optical lens utilized in imaging optical systems was examined via simulation and experimental. The findings demonstrate that the suggested method successfully performs deformation analysis of plastic optical lenses post-injection molding.
