The automotive industry uses many plastic components that require reliable and repeatable joining methods. Ultrasonic welding can be considered for suitable thermoplastic assemblies because it can produce localized heating at the joint interface and achieve short cycle times.
Automotive applications may include housings, interior components, electrical parts, filters and other plastic assemblies. The exact welding configuration depends on the material, component geometry, joint design and production requirements.
This article explores how ultrasonic welding can be used for automotive plastic components and what manufacturers should consider when selecting ultrasonic machines, converters, boosters and horns.
