Extrusion

Virtual simulation can help engineers to enhance the extrusion process by modeling critical components, such as screws, to ensure a high-quality end product. Software from ANSYS quantifies mixing characteristics, residence time and shear rates in extruders, allowing engineers to evaluate how design and operating condition modifications can affect mixing quality as well as gain a better understanding of the complex motion of particles in these devices. ANSYS tools not only reveal the quality of the mixing and extruding process, but allow a qualitative comparison of different mixing and extruding configurations.
