Systèmes de refroidissementIndex. décimale : 668.4 Plastiques, vinyles Résumé : Based on simulations and prototype production, the influence of an additive manufactured injection molding tool cavity on the manufacturing process was investigated. Due to the improved cooling performance, the cycle time can be reduced by approximately 10 %, whereas at the same time, a high dimensional stability of the polybutylene terephthalate (PBT) component can be achieved. Note de contenu : - Metal substitution for the new mobility
- Conformal cooling from additive manufacturing as the method of choice
- Highest dimensional accuracy as a must for metal rep
Lacement
- Increasing cooling performance for higher production efficiency
- Gentle material treatment while faster processing
- Successful realization of the project

Torsion (mécanique)Index. décimale : 668.4 Plastiques, vinyles Résumé : Plastic/metal hybrid structures for industrial applications have been established for years, e. g. for front-end carriers in automotive vehicles. Previously, in assembly injection molding joints were based on form/force fit or friction locking. Novel adhesion promoters now permit adhesive bonding of hybrid structures with improved component properties. Note de contenu : - The hylight process
- Confirmed by close-to-production tests
- Weight savings of some 20 percent possible
- FIGURES : Established plastic/metal hybrid structures : front-end carriers, for example, are mounted in automobiles (here in the Ford C-MAX) as mass-produced lightweight hybrid components - 1. Improved component properties : concepts for joining metal and plastic components and their characteristics - 2. Erlanger carrier : the model component combines important design features of series parts, thereby permitting complex components tests - 3. Hylight process : the processing chain for producing plastic/metal hybrid components - 4. Test setup : hood latch test and torsion test - 5. Overview of the front-end carrier's performance increase - 6.
