- Abstract:
- Due to the huge difference between macroscopic part size and micro-feature size, the injection molding filling process with micro-feature is a typical geometric multi-scale structure flow and heat transfer problem. The flow and heat transfer behavior of the injection molding process with microstructure was analyzed by numerical and analytical methods, the macroscopic filling process was dynamically simulated based on the finite element/finite difference method, and the quantitative relationship between the filling distance in the microstructure and the inlet pressure, size, flow velocity and material properties of the microstructure was established by the analytical method, and the effects of macro mold temperature, injection rate and micro-feature size on the micro-feature filling distance were analyzed in detail.
