Automotive Plastic Welding Solutions | Ultrasonic Welding for High-Volume Production

Intro

Automotive plastic components require high structural strength, tight dimensional control,

and long-term consistencyFor EU and US automotive factories and Tier suppliers, welding solutions 

must perform reliably under multi-shift production, strict quality standards, and continuous process

validation.

Our automotive plastic welding solutions are designed to deliver stable weld strength, cosmetic-safe 

appearance, and repeatable results, supporting modern automotive manufacturing requirements.

Typical Applications

• Interior trim components (panels, clips, brackets)

• Functional plastic parts (sensor housings, covers, caps)

• Fluid-related components (reservoir parts, valves, connectors)

• Air duct and HVAC plastic assemblies

• Electrical housings and protective enclosures

Key Challenges

• High-volume production requires extreme process stability

• Inconsistent weld strength leads to functional failures

• Cosmetic defects are not acceptable for visible components

• Tight cycle time requirements limit process window

• Automation integration is often mandatory

Solution Highlights

• Precision-controlled ultrasonic welding ensures stable weld strength across long production runs

• Automatic frequency tracking maintains consistent energy output under varying part tolerances

• Rigid mechanical structure minimizes vibration and positional deviation

• Optimized horn and fixture design protects cosmetic surfaces

• Automation-ready architecture supports integration into automotive production lines

Recommended Systems

High Precision Ultrasonic Welding Machine

• Designed for continuous, high-duty-cycle automotive production
