| Résumé : |
Short product lifecycles and high demands on injection molded parts require efficient product development methods. Besides new process management strategies, simulation is an important component at an early stage of product and mold development. This article validates the simulation of the water-assisted injection molding technique, compares two fluid-assisted injection molding techniques (FAIM) and presents a typical practical application. |

- Residual wall thickness as quality feature
- Validation of the simulation with a comparison of the cooling efficiency of WAIM vs GAIM
- Practical decision-making aid : which process is suitable ?
- Simulating the grip for the thermomix
- Fig. 1 : Simulation of the media line with water bubble and distribution of the measurement positions and measurement points of the residual wall thicknesses over the cross-section
- Fig. 2 : Comparison between reality and simulation with the aid of the redidual wall thicknesses (T, L, B, R), eccentricity (E) and the area ratio of the displaced molten core (A) for MP2 and MP 3, indicating the 3δ range
- Fig. 3 : Numerical comparison of the cooling efficiency of WAIM and GAIM indicating the sensor position on the media line for the measurement
- Fig. 4 : Because of its digital capabilities, the Thermomix has become known as the 'iPhone from Wuppertal"
- Fig. 5 : Movable moldhalf (AS), stationary mold half (DS) with slide elements show open
- Fig. 6 : Overview of the simulation model with temperature-control system, cold runner, cavity and overspill cavity. Simulating the grip for the mixing bowl of the Thermomix, showing the water bubble in the part overspill cavity |
