Simulation in 2K injection molding

Filling studies in 2K silicone injection molding

Simulation-based analysis for optiomal tool design 

 

Filling studies show how silicone material behaves in the mold even before the mold is created. They significantly improve process stability and enable precise design in silicone injection molding—especially in 2-component injection molding.

Key analysis points:

  • Optimal positioning of the injection points
  • Meaningful filling pattern
  • Early detection of air pockets
  • Temperature and pressure distribution in the mold
  • Analysis of shrinkage and warpage
  • Multi-cycle analysis for real series conditions

Advantage: Reduced iteration loops, lower development costs, higher process reliability.

 

FEM simulations

Component optimization prior to manufacturing

FEM simulations (finite element method) enable the mechanical properties of silicone components to be calculated precisely in advance. This allows us to ensure that components are resilient, function reliably, and can be produced economically in later use.

We simulate:

  • Stresses, deformations, and component stiffness
  • Optimal wall thicknesses and material distribution
  • Component design based on real loads
  • Compliance with technical requirements and specifications

Result: Weak points become visible—and are eliminated before they arise.
