| Résumé : |
Thermoplastic foam injection molding enables lower melt viscosity due to the addition of blowing agent, which is also attractive for the production of thin-walled packaging. Since injection molded packaging is often decorated through in-mold-labeling, it is important to understand how the blowing agent affects adhesion between the film and the molded part to avoid bubble formation at the interface. |

- Lower injection pressure due to the addition of blowing agent and IML
- Influence on Film Adhesion and Optical Appearance
- Influence of blowing agent on molded part warpage
- Foam injection molding in thin-wall applications
- Figure : Selecting the right IML film is critical for visually appealing molded parts
- Fig. 1 : Sheet geometry with flow aids was used for the tests
- Fig. 2 : The injection pressure is reduced by the blowing agent
- Fig. 3 : Influence of different IML films on the injection pressure with and without blowing agent for PHC27 and a 0.5 mm thick sheet
- Fig. 4 : Warpage X is defined as the distance between the highest and the lowest point in the side view of the sheet
- Fig. 5 : Influence of IML film on the molding warpage of a 0.5 mm thick sheet of PHC27
- Table 1 : The following polypropylene grades were processed in the trials using the MuCell process
- Table 2 : IML films with different optical and haptic properties and thicknesses were selected for the back-molding tests |
