Welding or embedding of thin membranes or films represents a great challenge that is easily mastered by ultrasonic welding. Moreover, the technology ensures unrestricted functionality, weld tightness, and particle purity, along with high outputs.
Housings of electrical components protect the functionality of the sensitive interior parts. Particularly with complex parts geometries, such as grip plates of surgery tools, ultrasonic welding provides solutions with dimensional accuracy and stability.
Tight and mark-free welding is possible with ultrasonics. The process fulfills absolutely all prerequisites, for example required for blood and dialysis filters. Medical products - many lives depend on their correct functionality
Due to soft welding by means of ultrasonics, facial masks have a remarkably high wearing comfort. Strong bonding of the multi-layer structure and good breathing permeability are guaranteed by continuous processing, as well as providing for high production rates. Fixation of elastic straps can be easily realized.
Ultrasonic sealing is the preferred technology for:
- Surgical face mask
- Duck mask
- 3D thermoformed blister mask
Sealing of medical packaging using ultrasonics guarantees tight joints despite powdered or pasty contents since ultrasonic vibration squeezes any product residues out of the sealing zone. Fast and safe welding of functional components by means of ultrasonics is also ensured, e.g. spouts on films. The use of less costly films is possible since no hot sealing layers are required.
Laminating or perforating different materials for wound dressing so that they remain breathable, sterile and soft – that is possible with ultrasonics. Due to the low energy input, ultrasonic welding does not have any negative effect on absorbency and feel.
