Ultrasonic Horns & Fixtures
Available in titanium, aluminum or hardened steel!
Sonitek offers full manufacturing and design services for Ultrasonic Horns & Part Fixturing/Nests with fast lead times.
Custom Ultrasonic Horns
Engineered to fit your special welding requirements
Nodal Plunger
|
A built-in spring-loaded isolated clamp is used to reduce stress damage on certain welding applications. They are ideal for staking applications that require a pre-clamp for a tight assembly. |
 |
Composite Horns
|
Ideal for welding large parts requiring high amplitude avoiding deep reliefs into the horn. They are also used to stake multiple studs or install several small inserts, reducing the need for additional welders. Large composite block horn for welding complex geometries. |
 |
Contoured Horns
|
Machined into the face of any horn directly from the molded part. These chrome plated horns are designed to weld complex geometrical shapes often found in the toy and medical industry. Contoured milled block horn (Chrome plated aluminum). |
 |
Standard Ultrasonic Horns
Exponential & Catenoidal Horns
|
These horns are available with tapped faces for replaceable tips up to 1" in diameter or with solid faces up to 2-1/2" and are available in titanium, aluminum, or hardened tool steel. All tapped horns are machined from titanium. Special faces can be machined onto these designs including contour milling and EDM machining. |
 |
Rectangular Horns 26" Long
|
Standard designs are available in lengths up to 26" long with a 2-1/2" maximum width. All of our horns are designed to vibrate with even amplitude across the entire face at reduced power. |
 |
Round Horns: Solid & Hollow
|
These horns are available with high or low gain ratios and are made from titanium or aluminum. The face diameter (working surface) can start at .010" O.D. and any dimensions up to 6" with a flat solid face. Plating such as hard chrome, carbide coatings, and titanium nitride are commonly used to protect against wear. |
 |
Block Horns/ Couplers
|
Machined from aluminum only, these horns are available up to 9" x 12". They require higher power units to run efficiently. Extender horns are sometimes attached to the face to weld applications requiring high amplitude or for parts with high profiles requiring deep relief cuts into a horn's face. |
 |
Composite Designs
|
Composite designs with standard horns allow us to provide concentrated energy where it needs to be. Any combination of horns can be "COUPLED" together to solve your welding application. |
 |
Round Solid Horns
|
(Larger horns have slotted faces) Up to 12-1/8" O.D. these horns are the most efficient designs for ultrasonic welding. |
