Multi-Layer Extrusion Simulation Module
Available from Compuplast International Inc (USA)
The COMPUPLAST® VEL™, Multi-Layer module™ is used for the analysis and design of multi-layer flow regions in coextrusion dies. Based on the Finite Element Method (FEM) of mathematical analysis, this program can provide the user with a very fast and accurate prediction of the basic flow characteristics needed to design a coextrusion system. Calculation speed is maximized by dividing the flow field into many small sections and performing a 1-D analysis, based on a fully developed flow assumption, in each section. Pressure drops, velocities, shear stresses and interface positions are some of the flow characteristics that are calculated. The user-friendly, intuitive interface and efficient solution technique allows the user to optimize channel designs quickly and easily.
