Many companies become lateral entrants in the mass production of Respirators, With the Ultrasonic cutting and welding Technology, respiratory masks can be mass-produced in a particularly resource-saving manner. Telsonic has adjusted to the current situation. The specialist in ultrasonic cutting and welding offers tailor-made equipment for the production of respiratory masks with significantly reduced delivery times.

Respiratory masks consist of different layers of fleece and cover material, depending on the application. Flat blanks are the starting product for the masks. They have to conform to a certain shape and be on the cut edges. Both can be implemented in one operation using ultrasound technology.

This is how ultrasonic cutting and welding work

Telsonic ultrasonic weldingA Form die and one oscillating at an ultrasonic frequency Tools contour parts are cut. The edge zone in the cut area is sealed by heating at the same time. Openings for valves or feedthroughs for looping the carrying straps can also be quickly made with clean cut edges using the separating welding process.

No residue forms on the blade, the process is practically wear-free and requires little energy without additives such as B. Glue. In addition, the cycle times for ultrasonic cutting and welding are extremely short. The modular ultrasonic components from Telsonic can be integrated very flexibly into automatic production lines.

The Control software The ultrasound system offers various trigger functions and welding modes. With multi-level amplitude and force profiles, all cutting, separating, welding and joining operations in protective mask production can be covered in high quality - from cutting and sealing the cut edges to welding the breathing valve and fixing nasal bridges and carrying straps.
