Plastic & Metal Welding Tooling


We design and manufacture a wide range of ultrasonic tools, sonotrodes/horns, with varying frequencies for all makes of machines, suitable for all welding applications.

High-Grade Aluminium is an excellent acoustic material from which to manufacture a  sonotrode.  It is relatively inexpensive and easy to machine. It can be anodised or hard anodised to reduce wear when welding lightly filled materials, plus anodising help prevent marking on white materials.


However, not recommended for the following;

  • Ultrasonic spot welding or riveting, though OK for low volume of trials

  • High gain applications and materials with medium to high levels of filler.

High-Grade Titanium is a very good acoustic material from which to manufacture a sonotrode. With tungsten carbide coating of the welding face, it shows good life even with high levels of fillers.

Tool Steel is suitable for a sonotrode after hardening and is ideal for thread inserting. With high internal resistance, it is only suitable for low to medium amplitude application.

CPM Steel is suitable for the manufacture of high amplitude sonotrodes. It can be precision harden up to 64 Rc to give excellent wear resistance when high levels of fillers are present in materials.

Frequency of Tooling Manufactured:-  20KHz, 30KHz, 35KHz, 36KHz & 40KHz

To suit most manufacturer's equipment, for example; Branson, KLN, Rinco, Kerrys, Hurfurth, Duckane, Telsonic, Mecasonic, Hermann, and Weber.

Holding fixtures along with its geometry is used to position and support the mouldings being processed.

Fixture Materials include steel, aluminium and cast resins. Sensitive Mouldings can be further protected by lining the fixture with materials such as cork or rubber PTFE
