Influence of Mesh Geometry and Mesh Refinement on Mathematical Models of Thermoplastic Injection Simulation Tools

摘要

The use of polymer materials by different segments of the industry has grown every year due to numerous advantages, being the injection of thermoplastics one of the processes most used to make this application viable. In order for these processes to be efficient and generate quality products, it is necessary that the polymer material be processed correctly. The simulation of thermoplastic injection is an important step in the manufacturing process of polymer products, where errors in the design and manufacture of the mold or product should be avoided even in the initial phase, as they directly affect the quality and cost of the product injected. This paper aims to perform a mesh refinement study between different mathematical models used in two thermoplastic injection systems (SolidWorks Plastics 2016 and Moldflow Synergy 2016), correlating the simulated results with the experimental results obtained in the process of trans formation of a product injected. The results showed that both software were able to simulate with certain precision the injection process studied, despite the small differences in injected masses predicted by the software.
