HIPS Product Cracking
Fenómeno do problema
HIPS products crack after a period of use.
Análise das causas
Internal stress release or contact with chemical media induces environmental stress cracking; HIPS is sensitive to oily media.; during on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based only on experience
Solução
①Reduce molding internal stress; ②avoid contact with incompatible media; ③do media compatibility verification; ④anneal when necessary.; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Conclusão principal
HIPS cracking should check two factors: stress and media; food contact applications should especially pay attention to the influence of oils.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
