PETG ultrasonic welding insufficient strength
Sorun Belirtisi
After ultrasonic welding of PETG products, the welding strength is low and they easily separate at the weld.
Neden Analizi
Ultrasonic welding parameters improper (amplitude, pressure, time not suitable), welding surface design poor, product moisture absorption affects welding.
Çözüm
Optimize welding parameters (amplitude 60-80%, pressure 0.2-0.4MPa); optimize energy director design; dry the products before welding.
Temel Çıkarım
PETG ultrasonic welding requires optimized welding parameters and joint design.
