Ultrasonic Welding of PCTG Products
Fenómeno del problema
After ultrasonic welding of the products, the strength is insufficient and the weld line easily comes apart.
Análisis de la causa
The welding parameters are improper (amplitude, time, pressure), product moisture absorption affects the welding effect, and the energy director design is poor.
Solución
Optimize the welding parameters; dry the products before welding; optimize the energy director design.
Conclusión clave
PCTG ultrasonic welding requires drying the products and optimizing the parameters.
