What factors affect the quality of ultrasonic plastic welding?

The quality of ultrasonic plastic welding (such as welding strength, sealing performance, appearance integrity, etc.) is influenced by multiple factors working together, and it needs to be comprehensively controlled from dimensions such as equipment parameters, material properties, workpiece design, and process operations. The following are the key influencing factors and their mechanisms:

1. Equipment parameters: Core control of energy and process
2. Material properties: Foundation of welding compatibility
3. Workpiece design: Key to energy transfer and melting control
4. Welding head and fixtures: "Bridge" for energy transfer and stability guarantee
5. Operations and environment: Interfering factors for process stability
