Abstract
Mold flow analysis technique was widely used to optimize the design of plastic parts and to predict the molding defects of injection.Main problems of evaluating and resolving the warp or deflection of plastic parts by mold flow analysis were pointed out based on actual applied experience.Every source of error existed in the process of mold flow was described and corresponding method was shown clearly.Some basic principles and applied methods of designing pre-deflection according to mold flow results were given and good effects were obtained,which will be of great benefit to relevant technical personnel.
