Calculating the mold-filling process for thin-walled injection moldings

Thin-wall molding

The application of rheological calculation programs in the design of injection moldings and injection molds is now state-of-the art. The programs required have undergone constant further development over the past few years.

The manufacturing of large-sized thin-walled parts like a panoramic roof made of Makrolon is supported by rheological calculation programs.
The manufacturing of large-sized thin-walled parts like a panoramic roof made of Makrolon® is supported by rheological calculation programs.

With the latest generation of programs, it is possible to divide up the flow channel cross-section into a number of layers and thus calculate injection moldings with very thin walls as well.

Freezing effects can be simulated under conditions similar to those that prevail in practice (These effects play a key role, particularly with thin walled molded parts).

Improved programs with the finite difference method lead  to more precise results.
