PETG transparent part optical distortion
문제 현상
When viewing objects through PETG products, distortion and deformation occur (optical distortion).
원인 분석
The product surface is uneven or thickness non-uniform causing uneven light refraction, internal stress causes local refractive index changes.
해결 방법
Optimize the flatness of the injection molded surface; uniform wall thickness; fully anneal to reduce internal stress.
핵심 요약
PETG optical distortion is a serious defect for transparent packaging.
