Optimization of injection molding parameters for lower chassis of luggage based on moldflow and orthogonal test
Taking the lower chassis of a bag as the research object,the injection molding numerical simulation analysis was carried out by using Moldflow and orthogonal test method.The effects of melt temperature,injection time,packing pressure,packing mode and mold temperature on the warpage were analyzed in order to find the best combination of process parameters to obtain the minimum warpage.The results showed that the influence degree of each factor on warpage deformation was as follows:packing pressure＞melt temperature＞packing method＞injection time＞mold temperature.The warpage deformation was 0.876 8 mm,which was 36％lower than the default process of 1.404 mm.It provided a theoretical guidance for the setting of the actual injection process parameters.
