Simulation software for plastic injection processes

Many plastics manufacturers are adopting numerical solutions to improve the performance of their products through more innovative and greener techniques and materials.
Then, they turned to rheology software to understand and analyze the phenomena related to the injection and expansion of polyurethane foams and other plastics.


What are your issues? How can simulation help you?


Mastering injection molding processes

To quickly and precisely analyze your manufacturing process from the injection to the cooling phase of the polymer or the expansion of the injected foam.


Anticipating defaults

To analyze your filling and expansion or cooling phases in order to predict the effects of underfilling, shrinking or even the appearance of air gaps.


Increasing productivity

To study the cycle times of your processes. Define the appropriate parameters to obtain quality parts with a reduced cycle time.

Take advantage of a wide range of plastics injection processes

REM3D_foam_injection_steering_wheelThanks to simulation, set up your standard injection processes but also more complex processes.
The thermo-rheological-kinetic coupling of the resolution allows a high level of prediction for the results, especially for foam injection and expansion.
You can estimate the minimum mass required for injection in order to perfectly fill the part but also predict the filling defects and optimize the vents and inserts location needed to the equilibrium of the expansion.
The global consideration of the rheological behaviors and the thermal phenomena during the injection cycle enables to know precisely the residual polymer thickness, especially for fluid-assisted injection.

REM3D_electrical_box_temperatureOur specialists listen to your needs and support your industrial projects with rheological analysis and quotations always
aligned with your requirements.
Thanks to our characterization laboratory, you can get material data perfectly fitting your own formulations to perform simulations with the most qualified data.

Optimize your processes of injection molding

Thanks to predictive simulation, analyze precisely heating maps, pressure evolutions but also foam density everywhere in the part.
Detect molding defects (unfilling, weld zone, shrinkage area,) and aesthetic defaults (setting up of the parting line, orange-peel skin effect) prior to manufacturing.

Then, you can optimize your development phase and validate innovative designs that reduce the weight of your final parts.

Testimonial DOW Benelux

“Accuracy of the simulation results is within the accuracy typical within experimental reproducibility. The REM3D® validation on industrial part shows a realistic flow pattern, predicts minimum fill and allow us to optimize molding conditions (temperatures, gating, venting). Finally, we obtain good density distribution prediction. Indeed, the software takes into account pressure effect (both internal and external) and gravity orientation, both processes parameters important for us.”
