Ultrasonic welding of medical devices is preferred by the industry because it typically removes the need for harsh chemical solvents or adhesives. This means any biocompatibility concerns that are common in the industry can be eliminated.
With ultrasonic welding systems from Herrmann Ultrasonics, manufacturers can enjoy continuous welding capabilities with a strong weld output. This equipment also produces faster welds, eliminating bottlenecks within their operations and increasing the speed of the entire manufacturing process. With medical device welding equipment from Herrmann Ultrasonics, users can monitor the process and optimize the system through a central control tablet. This provides greater ease of use as well as centralized data for making the most informed decisions concerning the efficacy of the technology.
Welding or embedding of thin membranes or films represents a great challenge that is easily mastered by ultrasonics. Moreover, the medical device welding 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 for medical applications provides solutions with dimensional accuracy and stability.
Wearable Medical Devices like Continuous Glucose Monitors (CGM) benefit from the use of ultrasonic welding. This gentle and clean technology uses high-frequency sound waves to weld the device together without adding excess stress to the delicate parts of the CGM systems while simultaneously eliminating the need for additional chemicals like glue or solvents.
Tight and mark-free welding for medical devices is possible with ultrasonics. The process fulfills absolutely all prerequisites, for example required for blood and dialysis filters. Welding of medical devices ensure correct functionality, based on industry standards, saving millions of lives.
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 with ultrasonic fabric welding for medical devices.
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 us 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.
Utilizing ultrasonics for medical component welding presents numerous advantages when compared to other joining techniques. When used for face masks, it provides a high level of comfort with durable connections between fleece layers, and the secure fixation of the elastic bands. 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.
Sealing of medical packaging using ultrasonics enables the ability to displace powdery or pasty filling goods from the seal area, which sets the foundation for creating a hermetic seam. Fast and safe welding of functional components utilizing ultrasonics is ensured, e.g. spouts on films. The use of ultrasonics provides material cost savings by decreasing headspace, resulting in a narrow seam.
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 medical welding does not have any negative effect on absorbency and feel.
