The purpose of this study is to analyse, by simulation, the injection of ABS plastic parts and track results on piece deformations after the latter was removed from the mould. Injection Process. Analysis was performed using the Autodesk Moldflow professional package. The results of the theoretical analysis by numerical methods are used for optimal design of the die to reduce and eliminate the strains and defect parts.
The paper presents some aspects regarding the sheet metal deep drawing process and shape optimzation for such parts using Finite Element Analysis. Simulation based design approaches have been used for forming processes. Using similar approach, a full process simulation and optimisation was undertaken in the present work. The work done here involved computer simulations of the forming processes to evaluate the amount of strain and stress each forming process contributed to the final product. Based on the simulation results, recommendation to change the product shape were presented. Not all the virtual products should be manufactured and the Finite Element Analysis eliminate all the possible errors and let the designers to optimize the geometry before designing the Molds and Dies for Deep Drawing process.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
