超薄平板塑件注射成型质量多目标优化
Multi-objective Optimization of Quality in Injection Molding of Ultra-thin Plate Plastic Parts
摘要
Abstract
Applying warp,flatness,size accuracy as an objective of quality in injection molding of ultra-thin plate plastic parts,models were established between the quality objective and the process variables which were based on Kriging method.And,with the NSGA-Ⅱ (Non-dominated Sorting Genetic Algorithm Ⅱ),a Pareto-optimal solution of quality multi-objectives was obtained.After that,the optimal solution which met the design requirements would be sought by using the vague evaluation,which realized the multi-objectives optimization of quality in the injection molding of ultra-thin plastic parts.The optimization process was applied to the ultra-thin light guide production practice which would greatly improve the molding precision and enhance the robustness of the injection molding process as well as prove the correctness and effectiveness of the optimization process,and provide a reliable theoretical method for the ultra-thin plastic parts manufacturing.关键词
