ULTRASONIC TECHNOLOGY FOR MASKS
ULTRASONIC SEALING IS THE PREFERRED TECHNOLOGY FOR
Surgical face mask (level 1-3)
(flat) with elastic threads, bands or extended fleece with ear cutout
Respirator mask N95, N100 (duck mask)
(“duck beak”) in different versions with vertical or horizontal fold, with or without breathing valve
3D thermoformed blister mask
with or without breathing valve
Surgical face mask (level 1-3)
Requirements surgical face mask
The material structure consisting of several layers is joined at various points by ultrasonic bonding for face masks to ensure shape and stability.
Technical solution surgical face mask
For high volumes, the product is being manufactured on a high-speed system of face mask machines with two ultrasonic stations:
In the first station, the fold and the edging, including the nose clip and the pleat fixation are continuously bonded. In the second station, after cutting and turning by 90°, the elastic threads or tapes are intermittently welded.
Configuration options surgical face mask
Our ultrasonic technology for face masks ensures the highest-quality results. For example, the MICROBOND CSI system with different sonotrodes and engraved anvils is used in high-speed continuous lines. Ultrasonic welding for face masks takes place in two stations. The patented MicrogapControl technology ensures continuous, reproducible bonding quality and allows a production rate of up to 1000 products per minute.
For small quantities, a quick-change system of individual components can be used instead of the MICROBOND CSI system. It is also possible to use a HiQ DIALOG welding machine integrated in a line or as a workstation for intermittent welding.
Web rolls 1,2,3: Three layers of nonwoven material are unwinding; inlaying melt blown layer determines filtering norm; more layers are feasible as well
Web roll 4: Nose-clip material (plastic or wire) is unwound, cut and inserted into NW layers
Ultrasonic station 1: Welding of layers lengthwise (including inserted nose-clip material) and middle fold (duck beak)
Web roll 5: Elastic material for ear loops is being cut and fed
Ultrasonic station 2: Welding of elastic threads or straps onto mask; folding of mask for last weld step
Ultrasonic station 3: Welding of side seams; mask is then stacked and packed
Respirator mask N95, N99, N100 (duck mask)
Requirements duck mask
The horizontal or vertical fold for the 'duck beak' is ultrasonically bonded; the lateral edges and the elastic fixation are also welded. If necessary, a breathing vavle is welded onto the mask by means of ultrasonics.
Technical solution duck mask
For high volumes, the product is being manufactured on a high-speed system with three ultrasonic stations: In the first station the layers are being bonded together and the nose clip is welded in In the second station the elastic bands are affixed After folding, the side seams are welded in the third ultrasonic station
Configuration options duck mask
The MICROBOND CSI system with different sonotrodes and engraved anvils is used for high-speed continuous lines. Welding takes place in three ultrasonic stations. The patented MicrogapControl technology ensures continuous, reproducible bonding quality and enables a production rate of up to 500 masks per minute.

3D thermoformed blister mask
Requirements 3D thermoformed blister mask
With this type of mask, a circumferential weld around the complete edge of the mask is performed, the elastic bands are welded and if necessary, the valve is welded on..
Technical solution and configuration options 3D thermoformed blister mask
The scope of supply for automated systems consists of a quick-change system with individual components or a VE SLIMLINE.
