What is Ultrasonic Welding?

Plastic products in all shapes and sizes have become an important part of our world. With a wide range of applications, their importance is often understated. When it comes to welding plastics, particularly wherever uncommon shapes need to be fused, ultrasonic machines offer an excellent approach. But what exactly are they, and how do they work?

Ultrasonic Machines in a Nutshell

What are ultrasonic machines? In a nutshell, they facilitate welding on plastics and metal through the use of high-frequency vibrations. These vibrations cause the material being welded to soften, from where pressure can be applied to fuse them together.

It offers an efficient and accurate approach to welding soft materials, particularly when odd dimensions make it difficult for other approaches to welding to achieve accurate results.

So let’s take a look at how it works:

How do they Work?

Plastic or metal parts are held together in the ultrasonic machine between a metal nest and a horn. Through this, pressure is applied to the material.

The horn then produces high-frequency vibrations which are substantial enough to cause the material to heat up and soften. Since there is pressure placed on the material through the nest, as it heats up, the pressure applied causes the parts to fuse together.

Once the objects have been fused together, the vibration stops, causing the material to cool and solidify.

This results in a completed weld and a solid object that cannot be separated afterwards.
