Welcome to Sonobond Ultrasonics

Sonobond Ultrasonics, Inc. is a leading provider of ultrasonic metal welding and textile bonding equipment for industries around the world.

In 1960, the company—then known as Aeroprojects—received the first patent ever awarded for ultrasonic metal welding. During the intervening years, Sonobond has earned an outstanding reputation for its pioneering work and quality engineered products. Today we manufacture a complete line of bonding and welding equipment for companies in the metals, plastics, and nonwovens/textiles industries. These include units for applications in aerospace, apparel, appliance, automotive, battery, body armor, electrical, electronic, environmental, filtration, HVAC, photovoltaic, and medical fields.

No adhesives, solder, thread, or other consumables are used. Instead, the process features a specially-designed head that channels high-frequency vibrations to create a rapid, localized buildup of heat in non-ferrous metals, rigid plastics, or synthetic fabrics. The resulting heat is then used to weld, bond, cut, or slit these materials without heating the surrounding area. The process is energy-efficient, ultra-reliable and produces consistent quality results.

Sonobond Ultrasonics equipment is available in both stand-alone and modular form. The modular units are designed for convenient integration into a production line or custom machinery. All models are easy to operate and require only minimal training.
