Ultrasonic Medical Welding

Ultrasonic medical welding ensures maintained functionality of the components and provides continuous process monitoring unrivaled by other processes. Up to 130 different process reference data are available and can be visualized.

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 medical devices allow for outstanding process monitoring and traceability, as well as data acquisition.

Application Engineering

Succcessful ultrasonic solutions

Membranes, adaptors, connectors

Welding or embedding of thin membranes or films represents a great challenge that is easily mastered by ultrasonic welding medical devices. Moreover, the medical device welding 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.

Ultrasonic sealing is the preferred technology for:

  • Surgical face mask
  • Duck mask
  • 3D thermoformed blister mask

During the pandemic, face masks have become a daily companion for all of us. They protect ourselves and give us security when dealing with others. In addition, they have long been part of everyday working life in many system-relevant professions. Especially when worn for longer periods of time, it becomes apparent that some masks are more comfortable to wear than others.

Modern ultrasonic welding technology sets a clear difference here compared to other joining techniques. Welding by means of ultrasound achieves a high level of wearing comfort with soft edges. The soft connection of several fleece layers and the secure fixation of the elastic bands are guaranteed. The absence of adhesive also ensures good breathability.

These advantages make daily wearing of the masks easier, especially for sensitive groups of people such as seniors and children. 

Sachets, pouches, and secondary packaging

Sealing of medical packaging using ultrasonics guarantees hermetic seals 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.
