DSONIK Ultrasonic Horn & Fixture Manufacturing

Precision Engineered for Reliable Ultrasonic Welding

At DSONIK, we understand that the performance of an ultrasonic plastic welding system depends heavily on two critical components—the ultrasonic horn (sonotrode) and the welding fixture. Even the most advanced ultrasonic welding machine cannot deliver consistent results without a properly designed, accurately tuned horn and a rigid, well-matched fixture.

With strong expertise in ultrasonic welding technology, DSONIK designs and manufactures customized ultrasonic horns and fixtures according to the geometry, material, welding area, and production requirements of each component.

Precision Ultrasonic Horn Manufacturing

Every DSONIK ultrasonic horn is engineered to achieve efficient transmission of ultrasonic energy from the transducer and booster to the plastic component. Particular attention is given to resonance frequency, amplitude distribution, stress concentration, contact surface, and dimensional accuracy.

Depending on the application, horns can be developed in aluminium alloy, titanium, or other suitable engineering materials. Our horn-development approach includes:

• Customized horn design according to component geometry
• Precise frequency tuning to match the ultrasonic welding system
• Optimized amplitude and vibration characteristics
• CNC machining for dimensional accuracy and repeatability
• Slot and relief design for larger or complex horns where required
• Surface treatment and wear-resistant solutions for demanding applications
• Final testing and tuning before installation

Customized Welding Fixtures

A correctly designed fixture is equally important because it supports the component during welding and helps maintain accurate alignment between the horn, weld joint, and plastic part.

DSONIK manufactures application-specific fixtures designed to provide stable support, accurate positioning, minimum component movement, and repeatable loading. Fixture materials and construction are selected according to component geometry, production volume, surface sensitivity, and welding pressure.

Horn & Fixture as a Complete Welding Solution

Instead of treating the horn and fixture as independent tooling, DSONIK focuses on them as a matched ultrasonic tooling system. Correct alignment, contact distribution, part support, amplitude, welding pressure, and joint design are evaluated together to achieve stronger and more consistent welds.

This approach helps manufacturers reduce common problems such as weak welding, leakage, marking, component deformation, inconsistent weld strength, excessive vibration, horn heating, and premature tooling failure.

Why Choose DSONIK?

From simple plastic components to complex industrial assemblies, DSONIK provides application-oriented horn and fixture development for industries including automotive, electrical and electronics, appliances, packaging, medical components, filters, consumer products and engineering plastics.

Our objective is simple: maximum ultrasonic energy transfer, minimum process variation, and dependable tooling life.
