Ultrasonic Plastic Welding
Ultrasonic plastic welding solutions deliver a reliable seal even on the most sensitive and exacting applications
Ultrasonic plastic welding is a fast and efficient technique that creates a strong, clean and hermetic seal, while increasing production without compromising quality. It is used for packaging, medical devices and other specialized applications that require a high-quality seal.
With high-performance ultrasonic welding machines and equipment, manufacturers can use fully automated solutions to create a reliable seal without the use of consumables. This advanced welding technology helps you meet environmental goals by increasing recyclability, reducing packaging material and eliminating chemicals adhesives and solvents.
Ultrasonic energy has been used to join thermoplastics for over 70 years. It is frequently chosen when parts are too complex or expensive to be molded in one piece.?
In ultrasonic plastic welding, a vibratory motion at the horn face (amplitude) is transferred to the part.? The vibrations move through the part and creates friction at the interface between the parts. Creating heat, then melting. When cooled, a weld is formed.
The ultrasonic welding process converts electrical energy into mechanical vibrations causing the plastics to join.?
In the ultrasonic stack, the converter transmits the energy through the booster causing the horn to vibrate.?
The converter is made up of piezoelectric ceramic disks that expand and contract at the same frequency of applied electrical energy.?
The booster increases or decreases the amplitude of the vibrations to provide the optimum amplitude for the material, size and type of assembly.
The Ultrasonic Welder is comprised of an actuator/stand and ultrasonic stack. The systems can be integrated into fully or semi-automated environments. Stand-alone models include an independent power supply and control interface.?
The systems support multiple weld modes, amplitude stepping and full control capabilities.

When Bosch needed to solve their packaging?challenges, they turned to Emerson’s joining technology expertise. Using Branson ultrasonic technology, Emerson delivered an integrated solution that met their unique requirements. The process provides a secure seal and consistent valve function.
After discovering that a design change compromised the integrity of their seal, Blendtec was forced to stop production. They enlisted Branson to develop a solution to ensure error-free production. Branson quickly and effectively delivered a custom solution within hours.
