COMPUPLAST® Virtual Extrusion Laboratory - Sheet Extrusion

The COMPUPLAST® Sheet Extrusion Package™  can be used to simulate the components of virtually any sheet extrusion line configuration including the production of coextruded sheet to help troubleshoot and optimize the process. It can be used to study the effect of changes in processing conditions, materials and equipment design. 

The package can be used to evaluate existing equipment or engineer new designs. The results not only include the flow distribution but also the shear stresses that may result in material stagnation inside the die and/or poor surface quality at the die exit. The package can be applied to both mono-layer and coextrusion processes. As such, problems like interfacial instabilities can also be solved.

With the Sheet Extrusion Packages, the user can avoid many problems due to improper equipment design and also reduce the number of physical experiments when developing a new product.

The COMPUPLAST® Virtual Extrusion Laboratory™ for Sheet Extrusion consists of several modules that can be purchased individually, or in combination, to simulate the various components in a Sheet Extrusion Process. 

The applicable VEL™ Modules are:

The VEL™ for Sheet Extrusion has been developed with the extrusion process engineer in mind. 

These modules can be used to help:

  • Optimize screw design
  • Optimize flow channel
  • Optimize mono and coex die design
  • Optimize chill roll configuration

The versatility and ease of use have truly made the COMPUPLAST™ VEL™ a valuable CAE tool.

The COMPUPLAST® VEL™ for Sheet Extrusion Package can help the user understand/solve the following problems:

  • unbalanced/uneven flow at the die exit
  • poor surface quality
  • material degradation inside the die and slow purging/color change
  • instabilities in coextrusion
  • poor feed-block design
  • problems related to the extruder performance such as surging, material overheating, material degradation and burning
