Ultrasonic Plastic Welding

Emerson ?welding solutions deliver a reliable seal even on the most sensitive and exacting applications.

Pairing Consistent Joint Quality with Streamlined Operation

This fast and efficient technique creates a strong, clean and hermetic seal, increasing production without compromising quality. It is used for packaging, medical devices and other specialized applications that require a high-quality seal.

High-performance benchtop and fully automated solutions create a reliable seal without the use of consumables. This advanced technology helps you meet environmental goals by increasing recyclability, reducing packaging material and eliminating chemicals adhesives and solvents.

How it Works

Ultrasonic Plastic Welding

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.

Conversion Sequence

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.

Ultrasonic Welder

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.
