Virtual Extrusion Laboratory - Spiral Die Module

The  COMPUPLAST®  VEL™, Spiral Die module™ is used for the analysis and design of the types of dies that are typically used in tubular (blown) film production. Using the fast, Control Volume Method (CVM) of mathematical analysis, or a fully 3D Finite Element Method (FEM), this module can provide the user with an accurate prediction of the expected die performance.

The parametric geometry editor allows a user to create and optimize a design quickly and efficiently

Combine it with the Multi-Layer or 2D FEM module and you have all the tools you need to analysis and design annular type multi-layer dies.

The VEL™, Spiral Die module has been developed with the extrusion process engineer in mind.  

Many world class blown film extrusion die manufacturers use the Spiral Die module as a part of their daily design procedures. Many processors and technical service personnel use this module to study and analyze the effect of resin changes on their process

In addition to tubular film dies, this module has also been successfully applied to the design of profile, tubing, pipe and blow molding dies. In fact, any extrusion application requiring a uniform annular flow can benefit from the Spiral Die module.
