ANALYSIS TYPE / 10
Flow Molding and Filling
Overview
Polymer and Metal Processing involves the analysis of fluid flow, heat transfer, and material behavior during manufacturing processes such as injection molding, extrusion, casting, and metal forming. CFD simulations are used to model the flow of molten polymer, predict temperature distributions, optimize cooling strategies, and analyze material behavior during shaping and solidification. This helps in designing efficient molds, reducing cycle times, minimizing defects, and improving the mechanical properties of polymer products. Non-Newtonian fluid models capture the complex viscosity behavior of molten materials during processing.
