Low ultrasonic welding strength of PET injection molded parts
Sorun Belirtisi
The strength of PET injection molded parts after ultrasonic welding is insufficient, and the weld line easily breaks.
Neden Analizi
Improper welding parameters (amplitude, energy, time unsuitable); product moisture absorption affects welding; energy director design is poor.
Çözüm
Optimize welding parameters; dry the products before welding; optimize energy director design (triangular cross-section).
Temel Çıkarım
PET ultrasonic welding requires dry products and optimized parameters.
