| Résumé : |
In the processing of long fiber-reinforced thermoplastic (LFT) components, the properties are significantly influenced by the mold temperature. Through variothermal process control, the optical and mechanical properties of LFT components are improved and the required compression force for component production is decreased. As a result, the investment in compression technology can be reduced. |
| Note de contenu : |
- Dynamic temperature changes for near-surface temperature control
- Halving the compression force
- Improving surface quality
- FIGURES : 1. Process sequence of LFT compression molding : conventional and variothermal - 2. Design of variothermal compression mold and exemplary temperature profile at mold - 3. Compression force depending on the heating circuit temperature - 4. Comparison of surface qualities of variothermal and conventional LFT compression mold components
- TABLE : Mold surface temperature after 8 min heating time depending on the heating circuit temperature |
