Plastic injection molding - Simulation and optimization

We simulate for you the complete injection moulding process of your plastic components. This includes the filling process of the component, the optimization of the distribution system as well as the regulation of the nozzles. We optimize the temperature distribution of the mold and generate the appropriate cooling strategy and determine a suitable holding pressure profile.

We determine strength properties of virtual extruded bodies for measures to prevent jetting, bubble inclusions, seams or hollow cavities. The finite element analysis provides the statements about stress concentrations, strength and vibration behaviour. Virtual injection molding and FEM analysis are repeated, to feasibility and to keep the costs under control. We support the same applications with other filling simulation software.

We give answers to questions:

  • How does the form fill?
  • Visible errors occur
  • Do distortions or deformations occur?
  • Can alternative materials be used?
  • Changeover times
  • Quesions about the cooling process
  • How large is the closing force?
  • What is the fiber orientation like?
  • Questions about the reprint phase
  • How long is the cycle time and can it be reduced?
  • Questions relating to shrinkage and delay
  • Questions on cascade optimization
  • Questions on the optimization of the gas pressure process
  • Distribution systems
