Injection molding and transfer molding simulation

To uncover risks and optimization potentials at an early stage, Hahn-Schickard utilizes injection molding simulations of thermoplastic or thermoset plastic components in the product development.

We continuously improve the accuracy of the injection molding simulation with experimental filling studies and the measurement of injection-molded parts.

Successful development of a plastic product and the associated injection molding tool with ever shorter development times requires a high degree of interdisciplinary competence, which necessitates extensive expertise in plastics engineering. The injection molding simulations help the tool designer in the design phase to better understand the filling of a plastic part and to identify problems, such as air bubbles or weld lines in the part. Moreover, our material database is a reliable basis for calculating process-specific variables, such as fill times, tool thermal properties, holding pressure times, cooling times, and many other parameters.

Rheological configuration

  • Fill behavior
  • Balance and optimization of the gating system, as well as gate position, and gate area
  • Formation and position of knit lines and air bubbles
  • Calculation of cooling time/crosslink time for thermosets
  • Calculation of fiber orientation
  • Loading of inserts

Thermal configuration

  • Temperature development in the tool and part
  • Optimization of tool thermal properties (e.g. cooling water/heating cartridges)
  • Influence of tool inserts

Other processes:

  • Two-component injection molding
  • Use of the material orientation for FEM
