DESIGN OF AN EXTRUSION DIE FOR PLASTIC PROFILES

摘要

The possibility is demonstrated of refined design by numerical modeling for molding channel geometry in extrusion heads for manufacturing plastic profiles. The aim of modeling is determination of channel head shape providing balanced flow at the die exit. The feasibility of modifying the molding channel using an optimization algorithm makes it possible to calculate molding channel head geometry for prescribed extruded object dimensions. A fluid dynamics Ansys Polyflow software package is used for extrusion head development.
