Ultrasonic Plastic Welding machine

Ultrasonic Plastic Welding Machine

High-quality ultrasonic transducer, strong power, good stability. Welding fast, each welding time only 0.01-9.99 seconds. Titanium alloy mold, for a variety of environments, difficult to damage. Compact design, small space. Low noise, good working environment. Low energy consumption, high efficiency, no distortion, no pollution, welding firm, and convenient operation. It can be accurately set and quickly adjusted parameters. Metal paint box, beautiful appearance, durable resistance to fall.



As a joining process for industrial thermoplastics, the ultrasonic method is very well proven in practice. Particularly in the production of mass- produced parts, the process offers definite advantage over previous methods such as for instance high strength,clean weld seams, fast processing time, extremely low rejection rates and low energy consumption. In addition, this technique can be used successfully for riveting, forming, stacking as well as embedding of metal parts into thermoplastic materials.

This Desktop High Power Ultrasonic Welding Machine adopts new generation of ultrasonic welding technology, which greatly shortens the processing time; a few milliseconds can complete the welding.


1.Rugged construction using the highest quality components provides superior performance precision and reliability.

2.Digi-Trac tuning automatically tracks the resonant frequency digitally.

3.Ultrasonic overload protection,with status indicator for ease of troubleshooting. The overload power limit is based on true RMS power output level.

4.Remote pneumatics availability offers increased flexibility in system integration

5.Line Voltage Regulation compensates for line fluctuations assuring consistent amplitude.

6.LED readouts display parameter settings - during setup and operation for easy reference and monitoring. LEDs are large and easy to read in most light conditions.

7.Hydraulic Speed Control offers precision hydraulic control of the melt velocity. This is critical to achieve maximum weld strength in staking, inserting and shear joint applications.

Working Principle

Ultrasonic welding machine is the use of ultrasonic generator to convert low current frequency to high frequency AC, then the same frequency of mechanical vibration by ultrasonic transducer.

Mechanical vibration transmitted to the ultrasonic welding joints by the amplitude modulator, the vibrational energy welding joints received transfer to the workpiece to be welded joint. In the region, the energy through friction converted into heat energy, to melt the plastic.

After vibration stopped, maintain short-term pressure makes the weldment on artifacts in molecular link way solidification as a whole.
