摘要：Aspherical lens molding error is closely related to molding process parameters such as molding temperature, molding speed, annealing rate and annealing holding force. Yet controlling the forming error to improve molding accuracy by optimizing molding process parameters means not only enormous workload, but also more difficulties in reconciling with each other among the various process parameters. In this paper, the methods of mould compensation and joint geometry modification are adopted to precorrect the surface shape of the mold cavity with the aid of MSC. Marc simulation software. The results of full value error compensation simulation indicate that mould compensation is effective in reducing the compression molding error of aspherical lens, and thereby high-quality non-spherical lens can be moulded.
