21. 9. 2022

This paper describes a case study dealing with the development of a three-layer product on a feed-block coextrusion system. The problems or phenomena that occurred during the product development experiments are explained via flow simulation and the rheological properties of the materials used. The results of the study are compared with real film samples produced during the development Article can be downloaded here. ...

Flow inside a die can be simulated by most of Compuplast VEL™ modules. An axi-symmetric or planar flow inside a die can be simulated by using the 2DFem module, any profile die can be simulated by the 3DFem module, some profile dies and designed profile dies can be simulated by using the Profile die module, flat dies, spiral dies, flat spiral dies (stackable dies) or cross-head dies can be simulated by using the appropriate module. In all these modules the...
