Manufacturers have several options for joining plastic components, including mechanical fasteners, adhesives, heat welding and ultrasonic welding. Each technology has different advantages depending on material, product design, production requirements and cost considerations.
Ultrasonic welding uses high-frequency mechanical vibration to generate localized heating at the joint interface. This can allow suitable thermoplastic components to be joined quickly without traditional adhesives or mechanical fasteners. The process is particularly useful where repeatability and automation are important.
This comparison guide explains the basic differences between ultrasonic welding and other plastic joining technologies and helps manufacturers understand when ultrasonic welding may be a suitable choice.
