PETG product fatigue fracture
문제 현상
Fatigue cracks appear under repeated bending or vibration loads and propagate to fracture.
원인 분석
Stress concentration points initiate fatigue cracks, internal stress in the product accelerates fatigue, and the material fatigue strength is insufficient.
해결 방법
Improve the design to reduce stress concentration; increase mold temperature to reduce internal stress; toughening modification if necessary.
핵심 요약
PETG fatigue performance is closely related to internal stress and design.
