Ultrasonic Tooling

Accusonics manufactures ultrasonic horns that are designed and manufactured to resonate at the correct frequency for many different machines. These typical frequencies are 15, 20, 25, 28, 30, 35, or 40 kHz (as well as some other frequencies), which the most common is 20kHz. However, since every application is unique, custom manufacturing assures that all special requirements are accommodated. Horns are acoustic devices and are designed to resonate at the frequency of the ultrasonic machine you are using. Therefore, the shape and length are extremely important, so they resonate correctly.

Most common horn materials are Aluminum, Titanium, and Steel..

  • Aluminum is the softest of all the materials. It can be chrome plated, or anodized to help decrease marking and increase wear resistance. It is the least cost of the 3 different types of materials, but will also wear faster. It is also the lightest of the materials.
  • Titanium wears better than the aluminum. It is normally the choice for longer running applications, and where more amplitude is needed to weld plastics that require more zip. It has the best elasticity of the 3 materials.
  • Steel is hardened for wear resistance. It is used widely where the plastic has a lot of filler such as glass or talc in it, or driving inserts into plastic bosses. Steel does have limitations on the amount of amplitude it handle, so most steel horns are smaller horns with less gain.
