Résumé : |
If several unfavorable conditions come together, the demands on joining technology grow, especially for medical technology products. Not only do they have to be leak-proof, but also satisfy requirements for validated and traceable welding processes. |
Note de contenu : |
- Weld force profiling and graphical representation of the parameters
- The ultrasonicc generator
- Tracking software for traceability
- FIGURES : 1. Secretion bottle with cap : welding the materials used (HDPE and LDPE) ightly proved a challenge - 2. Circumferential weld seam : a round blue cap is welded onto a transparent secretion bottle - 3. Product line : a vertically adjustable fixture was required to compensate different heights - 4. HiQ Dialog 6200 : The ultrasonic welding machine has a vertically adjustable tool holder and can display the weld course graphically on its 15-inch screen - 5. The courses of the parameters joining distance (RPN), power (P), and force (F), as well as the correct selection of amplitude (here : 45.9 µm) and requency (here : 20,268 Hz) are the keys to successful process settings |
