MS sonxTOP Ultrasonic Plastic Welding Machines
Ultrasonic plastic welding is a method of joining two pieces of thermoplastic together seamlessly using high frequencies. An ultrasonic plastic welding machine converts high-frequency electrical energy into high-frequency mechanical energy to fuse parts without changing their state from solid to liquid. Since no melting occurs, the joints created are so strong and seamless that they even rival the material characteristics of injection molding. In addition, ultrasonic technology is used to make clean and precise cuts through many types of materials.
Ultrasonic plastic welding machines are used throughout nearly every industry, including automotive, food and beverage, medical, aerospace, electrical, and more. This technology is used to process and join films, textiles, and thermoplastics, or even cut foods. At MS Ultrasonic Technology Group, we offer a range of custom and standard ultrasonic plastic welding machines, including the MS sonxTOP series. Our machines provide versatile solutions for many applications, including consumer goods, medical technology, automotive, and more.
Features of Our Ultrasonic Plastic Welding Machines
Ultrasonic plastic welders from MS Ultrasonic Technology Group have been engineered to provide the highest possible level of performance and innovation. Some key features you’ll find in our MS sonxTOP series include:
Our machines are designed with modular components, facilitating maximum customization and adaptability. Choose between a tabletop design, column, or inline machine based on your needs. We also offer all the accessories you might want, such as work tables or sound-insulating cabinets.
Our unique, patented preciSer® servo drive delivers unrivaled precision as well as force and speed control.
We've incorporated numerous safety features, including real-time error detection and remote monitoring using our specially developed app.
A 100% electric drive concept provides energy-saving capabilities and helps contribute toward sustainable manufacturing. Our equipment delivers high productivity without the need for costly compressed air.
An intuitive interface simplifies machine setup and operation. We use touchscreen technology and clear and intuitive HMI color displays. The icons and graphics are instinctive to use, and all information is presented in clear, easy-to-read tables. In addition, we've made it simple to read and save welding parameters.

MS sonxTOP ultrasonic plastic welding machines are able to comply with even the smallest tolerances and produce repeatable, high-quality results for welding paths and processes. Our technology provides unrivaled positioning accuracy that greatly reduces reject costs. We developed this technology based on a universally applicable drive concept to ensure a maximum range of uses throughout industry-diverse applications.
It’s also possible to network multiple ultrasonic servo processes and operate them centrally from a single controller. Since there are no manual machine adjustments, making changes between jobs is fast and effortless. Simply recall an established program and begin production. It’s fast and simple to change workpiece carriers and resonant units, and since no additional tools are required, downtime is significantly reduced.

Ultrasonic Plastic Welding Machine Industry Applications
Our ultrasonic plastic welding machines are used throughout numerous applications, including the following:
Our technology is used to produce both interior and exterior automotive components, from instrument panels and column claddings to wheel arch trims and tailgates. Automotive applications benefit from the flawless appearance and short process times our equipment facilitates.
The medical industry demands high performance and safety. Our equipment produces medical devices that adhere to the most stringent quality standards while performing at maximum efficiency. Produce dialysis filters, blood pumps, protection masks, infusion filters, and many other types of medical and pharmaceutical devices while adhering to FDA, ISO 14644-1, and all other relevant requirements.
Everything from washing machine covers to electronics and packaging can be created using MS sonxTOP technology. Our systems create consumer goods that adhere to the highest safety and performance standards. It is also used to safely integrate an electronic component within a housing without damaging any sensitive surrounding electronics. Our equipment is suitable for both small batches and full-series production.
Our technology contributes to fabric-related manufacturing by cutting and sealing both fabric and nonwoven edge fibers. Our machines are easily integrated into an existing concept or a new system and can help create everything from hygiene articles to hook-and-loop fasteners, awnings, and much more.
Safety and cost-effectiveness are extremely important in the food industry. Our technology creates perfect packaging seals to prevent contamination along seams and effectively joins spouts or valves to packaging materials. MS sonxTOP and our MS sonxSYS systems provide precision cutting and food processing for everything from cakes and confectionaries to cheese without squeezing or deforming the products.
