Ultrasonic Welding of PCTG Products
Problem Phenomenon
After ultrasonic welding of the products, the strength is insufficient and the weld line easily comes apart.
Cause Analysis
The welding parameters are improper (amplitude, time, pressure), product moisture absorption affects the welding effect, and the energy director design is poor.
Solution
Optimize the welding parameters; dry the products before welding; optimize the energy director design.
Key Takeaway
PCTG ultrasonic welding requires drying the products and optimizing the parameters.
