Rheology & Structure calculations
Predicting how the material will behave before manufacturing
Numerical simulation makes it possible to anticipate injection defects, deformations and failures — before any investment in tooling. CadNov masters these tools to reduce your iterations and secure your projects.
Why simulate before molding?
A mold costs between €5 000 and 80 000. A change after the first shot costs between €2 000 and 30 000. Simulation makes it possible to identify problems upstream — when corrections still cost nothing.
Our expertise
CadNov combines the plastics engineer's hands-on knowledge with mastery of numerical simulation tools. Our analyses are always grounded in the reality of manufacturing — not just theoretical calculations.
Polymer rheology
Understanding how the material behaves to process it better
Measuring viscosity as a function of shear rate. Selecting the optimal injection grade.
Analysis of filling, cooling and warpage. Prediction of weld lines and sink-mark areas before the mold is made.
Determining the optimal injection point to balance filling, reduce residual stresses and avoid deformation.
Analysis of the polymer's thermomechanical behavior under real conditions. Verification of material / process / requirements compatibility.

Structure calculations (FEM)
Checking the mechanical strength of your plastic parts before production
Verification of strength under static load. Identification of high-stress areas, failure risks and safety factors.
Calculation of displacements under load. Verification of dimensional conformity in service. Prediction of warpage and functional clearances.
Determination of natural vibration frequencies. Avoidance of resonance phenomena in service. Analysis of impact response.
Reduction of material mass while maintaining mechanical performance. Ideal for injection-molded parts to be optimized for material cost.
