| Résumé : |
In a research project being carried out by the IKV and KTP, the influence of geometric and process parameters on the quality of the screw connection in the direct assembly of thermosetting plastics has been analyzed. The research results show that, in addition to the geometric design, the production parameters offer additional optimization potential for the reliability of the screw connection. The compactness and curing degree of the parts exert the largest influence. |
| Note de contenu : |
- Measuring the torque guarantees a reliable screw joint
- Geometry influences flank coverage and quality of the screw connection
- Injection molding parameters further optimize the quality of the screw joint
- Fig. 1 : In order to better understand the influences exerted on direct screwing processes in thermoset molding compounds, the screw connection is designed and optimized in an iterative process
- Fig. 2 : Sketch of the screw-in tube with the varied geometry parameters. A modular mold structure allows an analysis of the different tube geometries
- Fig. 3 : Influence of the geometry parameters : a high differential torque provides for adequate space before failure of the screw connection and thus ensures a higher quality of the joint
- Fig. 4 : Evaluation of the significance analysis: the largest influence on the quality of the screw connection comes from the holding phase and the subsequent curing time
- Table 1 : Factors and steps for the injection molding tests |
