Ultrasonic System for Automatic Welding Machine
Robotic automation welding technology delivers greater flexibility in series production and assembly, significantly boosting productivity. The compact, lightweight ultrasonic actuator is easy to assemble and can be readily mounted on robotic arms. When integrated with robotic automation control systems, these actuators achieve highly efficient, repeatable ultrasonic welding results
The ultrasonic actuator consists of a converter, coupler, horn, cylinder, and cylinder support. In addition to standard ultrasonic welding machines, MCSONIC offers a comprehensive range of ultrasonic actuators tailored for machine builders and automation specialists. Backed by over 10 years of ultrasonic welding expertise, we provide professional consultation and customized solutions to meet your specific needs.
Ultrasonic actuator assembly connected to the Robot:
| Component | Function |
| Mounting | Robotic arm, gantry or custom line fixture |
| Converter | Industrial ultrasonic transducer that turns the generator signal into vibration |
| Coupler | Carries the vibration from the converter down to the horn |
| Horn | Welding contact, profiled to the joint on your part |
| Cylinder | Applies the welding stroke |
| Cylinder support | Carries the stroke assembly and bolts to the machine |
| Body | Compact and lightweight, easy to assemble and mount |
| Generator | Matched to the actuator for the application |
| Frequency | Confirmed with our engineers against the part and stack |
Unsure which ultrasonic system fits your workpiece or production line? MCSONIC's engineering team helps you select the right machine, horn or blade configuration before you order, backed by over 15 years specializing in ultrasonic cutting and systems widely used in factories worldwide. We support customization of key parameters, integration into existing automation lines, and clear guidance on installation, commissioning and daily operation. Our after-sales engineers help troubleshoot issues remotely or on site, and selected systems support remote diagnostics. Send us your drawings, samples or cycle targets and we will recommend a practical configuration.
The actuator is built around an industrial ultrasonic transducer and supplies the weld stroke itself. Everything around that stays with your machine: feeding and clamping the part, the generator and its settings, and the motion that brings the joint under the welding head. Because the stack is built for your part, the unit can be added without changing how the line feeds or holds components.
Yes. Carried on a robotic arm, the actuator can be programmed to weld one position, move on to the next and repeat, which is often simpler than installing a full ultrasonic welding system at every point. The number of welds and the part design decide how those positions are sequenced; send us the drawing and we will advise on a practical order.
It is designed to be carried by a robotic arm and to mount into automated production equipment, so the fixing plate is specified against your robot model or fixture drawing. The compact, light body also suits gantries and custom frames where a welding press would not fit. Share the interface details with our engineers and we will confirm the plate and stack before the unit is built.
The horn sits at the end of the stack and can be replaced when the weld area changes or the contact face wears. Fit the new ultrasonic horn, then re-check the weld settings on trial parts, because a different profile changes how the energy reaches the joint. Send the revised part drawing or a sample so the horn is profiled to the joint before you run production.
Because there is no press base or separate column to house, the space taken up is essentially the welding head itself, its mounting plate and a route for the cables. That matters in cells where parts move through a fixture with limited clearance above or beside the joint. Tell us the clearances you have and we will confirm the mounting arrangement and stack length before the unit is built.
Work like this is usually handled as a custom ultrasonic plastic welding solution: the horn, stack and mounting details are set against your drawings and the way your cell presents the part, so a revision normally means updating the stack rather than replacing the whole unit. Tell us what has changed — part geometry, material or cycle — and our engineers will confirm what needs to be rechecked before you run production.
