Drug delivery systems
Inhalers, nebulizers, nasal drug delivery systems
These drug delivery systems require precise and reliable assembly to ensure accurate medication delivery throughout the product’s service life. Conventional thermal joining methods often introduce heat into adjacent areas, which can lead to component deformation, dimensional deviations, or stress on sensitive drug delivery mechanisms. Ultrasonic joining technology concentrates the energy precisely at the joining area, enabling strong, reproducible joints while minimizing the thermal impact on other components.
Components: Metered-dose inhalers (MDI), pressurized metered-dose inhalers (pMDI), dry powder inhalers (DPI), soft mist inhalers
Industry: Medical
Material: Polypropylene (PP)
Joining processes: Ultrasonic welding, riveting, embedding, spot welding
Benefits: High-precision, fast joining of plastics and filters
Requirements
- High leak-tightness to protect the drug
- Precise positioning of functional components
- High dimensional accuracy for reproducible dosing
- Low thermal impact on sensitive components
