PETG ultrasonic welding insufficient strength
문제 현상
After ultrasonic welding of PETG products, the welding strength is low and they easily separate at the weld.
원인 분석
Ultrasonic welding parameters improper (amplitude, pressure, time not suitable), welding surface design poor, product moisture absorption affects welding.
해결 방법
Optimize welding parameters (amplitude 60-80%, pressure 0.2-0.4MPa); optimize energy director design; dry the products before welding.
핵심 요약
PETG ultrasonic welding requires optimized welding parameters and joint design.
