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...
