Welding of medical devices
WELDING OF MEDICAL DEVICES
Medical devices that are ultrasonically welded in very large amounts are almost always filters for:
- Oxygen therapy
- Pediatric dialysis
- Cardio therapy
- Intravenous therapy
- Catheters’ terminals
The fantastic advantages of using ultrasonic welding is in the repeatability of the operation, the filing of machining data, the welding speed and the aesthetic cleanliness of the welding itself.
Each single product must be designed to be welded with ultrasounds, also identifying the degree of mechanical and hydraulic sealing and, potentially, the types of stresses and testing to which they are subjected to.
Sonotrodes and the installation guide pieces are always built ad hoc and are mainly made of a titanium alloy.
Welding machines used for the production of medical devices can be used with various frequencies, from 35 to 20 kHz.
SONIC ITALIA makes available its technical expertise and its ultrasonic cutting and welding equipment to OEMs.
