Unstable shrinkage of EAA
Fenómeno del problema
The shrinkage of EAA products fluctuates ±0.8%, exceeding the ±0.2% requirement
Análisis de la causa
Molecular weight differences between different batches of EAA cause shrinkage changes; processing temperature fluctuations affect crystallinity and thus shrinkage
Solución
1) Strictly control the consistency of raw material batches; 2) Stabilize the processing temperature ±2°C to ensure consistent crystallinity; 3) Reserve adjustment space for mold shrinkage compensation
Conclusión clave
Unstable shrinkage is caused by batch differences and temperature fluctuations; raw material and temperature control are the key
