Stress cracking of PLA injection molded products
Fenómeno del problema
The product cracks during storage or use.
Análisis de la causa
The molding internal stress is too large (fast cooling), and the inherent brittleness of PLA is sensitive to stress concentration.
Solución
Raise the mold temperature to reduce the cooling rate; avoid sharp corners in product design; anneal at 60-80°C.
Conclusión clave
PLA stress cracking is related to its inherent brittleness.
