The Importance of Ultrasonic Plastic Welding

What Is Ultrasonic Welding? Ultrasonic plastic welding is a state-of-the-art technology used to form a permanent bond. Mechanical vibrations generate frictional heat until the plastic parts reach melting point and can be pressed together. The advantage of ultrasonic plastic welding is that it can be applied to embed metal parts...

Practical Uses of Ultrasonic Welders

Ultrasonic welders have multiple uses. Frequently applied to fuse small- and medium-size thermoplastic parts, ultrasonic welding machines are used in automotive applications, computers, electronics, toys, textiles and house appliances. How Do Ultrasonic Welders Work? Plastic parts are joined together through pressure and high frequency mechanical vibrations, which create frictional heat...

The Components of Ultrasonic Welding

In ultrasonic welding, there are three variables to consider: time, pressure and amplitude. All three need to be taken into consideration to control the process. But before we can delve into these considerations, we need to understand the main components of this type of welding. Ultrasonic welding equipment consists of...

Companies Rely On Ultrasonic Welding

Back in the 1960s, the first plastic car was created using ultrasonic welding. Its creators had hoped that plastic cars would replace metal cars. It didn’t happen. Plastic cars never caught on. But ultrasonic welding did, and in a big way. Today, several industries including packaging companies, computer conglomerates, electrical...

Thermoplastic Polymers Suitable For Ultrasonic Plastic Welding

Understanding Ultrasonic Plastic Welding Ultrasonic plastic welding relies on the materials softening and not necessarily melting with increased temperature. This makes ultrasonic plastic welding suitable for thermoplastic polymers, but not thermosets. So what does this all mean? Most thermoplastic polymers have an amorphous structure with varying degrees of crystallinity (the...
