气辅成型工艺参数正交精准设计优化
Orthogonal precision design optimization of gas-assisted molding process parameters
摘要
Abstract
Based on the dual-carbon goal,the gas-assisted molding technology can provide an effective way for plastic mold-ing to reduce carbon emissions.To design the gas-assisted molding parameters accurately,improve the gas-assisted molding quality and efficiency,and reduce carbon emissions effectively,the orthogonal optimization with a parameter interaction was studied through 3D numerical simulation and experiments.The results indicated that the parameter interaction had little ef-fect on the gas penetration length but a significant effect on the gas finger defect.Based on the range analysis,the optimized parameter group was obtained at a polymer temperature of 240℃,a gas injection pressure of 3 MPa,a delay time of 4 s,and a mold temperature of 40℃.The numerical simulation and experiments indicated that the gas penetration length and gas fin-ger under the optimized parameter group were excellent,which could be used in the actual gas-assisted molding production.关键词
