SoniXs Ultrasonic Sealing Technology
Joining the two open ends of the strap loop is decisive in the modern strapping technology: Economical efficiency in terms of Total Cost of Ownership combined with outstanding performance are in demand. Mosca’s proprietary SoniXs ultrasonic sealing heads have revolutionized strapping systems offering significant and proven advantages over traditional heat-seal technologies, including cost, maintenance, and longevity across all industries and applications. SoniXs sealing heads are available on most bundlers, and all load securing systems and unitizers. It is now our customers preferred method of sealing on strapping machines from Mosca.


Sustainable, efficient and economical with reliable performance
Using ultrasonic waves to weld strap ends together, SoniXs technology is able to safely and reliably seal, creating no harmful smoke, fumes, or smells often associated with heat or friction sealing methods. For increased sustainability, SoniXs only uses energy during the sealing process with no warm-up time required.

What is ultrasonic welding and how does it work?
When strapping is sealed with ultrasound, low-amplitude, high-frequency vibrations are transmitted to both ends of the plastic strap. The sonotrode - the heart of the ultrasonic unit - welds the strap ends together, ensuring an even, extremely stable seal to secure the products. Thanks to the unique embossing at the sealing point, our customers can also easily detect and prevent tampering.
In contrast to thermal welding processes, SoniXs are produced with low process heat: This reduces energy costs and increases safety during the sealing process, as no emissions are emitted. The self-calibrating system is also user-friendly and requires minimal maintenance. At the same time, it reduces wear, as no residue is produced during the sealing process.
Wesentliche Vorteile
+ INCREASED SEAL STRENGTH
SoniXs allows strapped products to withstand significant stress, enabling the use of thinner, narrower strapping materials without loss of performance.
+ COST SAVINGS
Increased seal strength reduces cost and the amount of strap needed per package without negatively impacting package quality or security.
+ LASTING DURABILITY
The innovative lever-type plunger, knife and horn drive with sealed bearing design ensures maximum service life with less wear.
+ CONSISTENT SEALING
The self-calibrating system monitors major parameters before every seal for consistent sealing in any environment.
+ WORRY-FREE PRODUCT SECUREMENT
SoniXs seals PP, PET and Paper straps with broad tension ranges, ensuring tight straps and secure bundles under all conditions and during transportation.
+ ENERGY CONSERVATION
SoniXs only uses power during the strapping cycle compared a heat-sealing system that uses constant resources.
+ LOW MAINTENANCE
Minimal maintenance is required as no residues are created during the sealing process. Our tool-less sealing head can be disassembled in 30 seconds allowing for quick and easy maintenance access.
+ SEALS PP, PET AND PAPER
Switch between PP, PET and Paper strap when needed. (Minor adjustments and part change may be required.)
<strong>WORK SAFETY & FIRE PROTECTION</strong>
As there is no significant heating during welding using SoniXs technology, there is no risk of injury. Furthermore, there is no fire risk for highly inflammable goods.
+ LOW NOISE LEVELS
The SoniXs sealing process causes no perceptible mechanical noise, which contributes to a pleasant working environment.
+ EFFICIENT
Thanks to the very short sealing time, ultrasonic sealing technology meets the high demands of tightly scheduled production.

The best solution for harsh wet environments
The stainless-steel corrosion-resistant version of Mosca‘s SoniXs sealing head is used in all Mosca stainless-steel bundlers for greater durability and performance in harsh and wet conditions found in meat, seafood, and poultry processing environments.
Combined with an IP56 cabinetry standard, Mosca‘s stainlesssteel range of strapping machines allows our customers to regularly achieve high cycle counts with low maintenance, a rarity in the industry.
