The requirements for quality and safety of medical parts are very high: in addition to tightness, strength and minimal generation of particles, process validation and process stability also are important factors in manufacturing.

Ultrasonic welding allows for outstanding process monitoring and traceability, as well as data acquisition.

Application groups

Membranes, adaptors, connectors

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.

Surgery instruments, functional components

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.

Fluid containers, filters

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

Breathing masks

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.

Sachets, pouches, and secondary packaging

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.

Wound dressing, bandaging material

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
