Ultrasonic Welding Plastics

Nordell have a comprehensive range of Ultrasonic welding machines and equipment along with many years of expertise in ultrasonic welding plastics. Our factory is operational 24 hours a day over two 12 hour shifts giving us the ability to provide ultrasonic welding services, fulfilling all your requirements.


We are able to ultrasonically weld a wide range of thermoplastics as well as products such as electronics and windows into instruments, case welding, Piezo stack sounder welding, insertion and general component joining.

What Is Ultrasonic Welding?

Ultrasonic welding is an industrial technique whereby high-frequency ultrasonic acoustic vibrations are locally applied to workpieces being held together under pressure to create a solid-state weld. It is commonly used for plastics and metals, and especially for joining dissimilar materials.


In ultrasonic welding, there are no connective bolts, nails, soldering materials, or adhesives necessary to bind the materials together. A notable characteristic of this method is that the temperature stays well below the melting point of the involved materials thus preventing any unwanted properties which may arise from high temperature exposure of the materials.


For joining complex injection moulded thermoplastic parts, ultrasonic welding equipment can be easily customized to fit the exact specifications of the parts being welded. Ultrasonic welding of thermoplastics causes local melting of the plastic due to absorption of vibrational energy along the joint to be welded. In metals, welding occurs due to high-pressure dispersion of surface oxides and local motion of the materials. Although there is heating, it is not enough to melt the base materials.


Ultrasonic Welding Of Plastics


Ultrasonic welding can be used for both hard and soft plastics, such as semi crystalline plastics, and metals. The understanding of ultrasonic welding has increased with research and testing. The invention of more sophisticated and inexpensive equipment and increased demand for plastic and electronic components has led to a growing knowledge of the fundamental process.
