Plastic Flow LLC of Houghton, Mich., has released a new version of its polyXtrue extrusion simulation software for die design.
The company has developed a completely new algorithm to simulate multilayer flow during polymer coextrusion. The algorithm now allows polyXtrue to predict the interface shape between adjacent polymer layers, even for highly complex die geometries.
Other new features include:
* The software now determines the shape of the streamlines along the interface between adjacent polymer layers, so the user can pinpoint the location in the feed block that needs to be modified to get the desired interface shape at the die exit.
* The new version has many options to generate three-dimensional finite element mesh. In particular, the new software now allows boundary layer meshes as well as extruded meshes.
The software also allows users to plot more variables, including residence time distribution for each polymer layer, velocity deviation across the die exit, shape of the interface between adjacent polymer layers at the die exit, shear-rate distribution and shear-stress distribution.
