FAQ – Ultrasonic Welding for Smart Vehicle Systems
Ultrasonic welding is the ideal solution for joining thermoplastics in automotive applications. It delivers strong, precise bonds for materials such as PP, PA, PBT, ABS, and PC+ABS blends. This process ensures reliable joints without adhesives or heat damage, making it perfect for a wide range of products and high-volume production.
Learn more about the right materials for ultrasonic welding in our free white paper “The most important success factors for component design”.
Ultrasonic welding creates strong, lasting connections by using mechanical vibrations and minimal force. During the welding time of 100 to 300 ms, friction at predefined joint areas melts the plastic in a controlled way. This forms a high-strength molecular bond without exposing the part to excessive heat or mechanical stress.
The result: joints that stay sealed and secure, even under extreme conditions like temperature changes, vibration, and mechanical loads – perfect for cameras, sensor housings and ADAS components.

Ultrasonic welding is exceptionally safe for delicate components.
The process uses mechanical vibrations and minimal force, applied only at predefined joint areas. Advanced control systems allow precise adjustment of parameters such as welding force and amplitude, ensuring consistent results without exposing sensitive electronics to heat or stress.
Sensitive electronics inside sensor housings, cameras or ADAS modules remain fully protected, while the process creates a strong, hermetic seal that keeps out dust, moisture, and other environmental influences.
Ultrasonic welding systems are designed to integrate smoothly into new or existing production environments. Their compact design helps save space, and plug-and-play functionality simplifies setup. Technical support from our global Team Automotive is always available to assist you with integration, helping you achieve maximum efficiency with minimal engineering effort.

Ultrasonic welding offers several practical advantages compared to adhesives and laser processes.
Unlike adhesives, it requires no curing time or additional materials, reducing process steps and eliminating consumables. This saves large sums in operating costs and reduces the machine footprint.
Compared to laser welding, ultrasonic welding works with a wide range of thermoplastics without needing transparent layers, making part design more flexible. The process is fast, energy-efficient, and suitable for automated production, delivering consistent, high-strength joints while supporting sustainability goals.
