ABAK warpage deformation
Fenómeno do problema
ABAK products warp; although improved compared to pure PA, management is still required, with crystallization and stress acting together.
Análise das causas
ABAK has better warpage resistance than pure PA; however, crystallization shrinkage of the PA component, uneven cooling, and internal stress still cause deformation; uneven wall thickness aggravates it; improper mold temperature.
Solução
①Control mold temperature uniformly at 60~80℃; ②optimize the holding pressure curve; ③design uniform wall thickness; ④ensure sufficient cooling time.; After adjustment, take consecutive samples to verify the effect, and resume mass production only after confirming stability
Conclusão principal
ABAK warpage improvement is an advantage over pure PA; however, process management is still necessary; uniformity is the core.; After confirming effectiveness, fix the parameters and practices into the work instructions to prevent recurrence
