Sorun Belirtisi
Insufficient strength and dimensional stability of tire cord
Neden Analizi
Tire cord requires high strength and low shrinkage; ordinary spinning processes cannot meet the requirements of skeleton materials; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Çözüm
Select high-viscosity chips; high-ratio drawing and heat-setting process; test dry heat shrinkage according to cord standards; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Temel Çıkarım
Tire cord is a dedicated route of high-viscosity chips plus high-ratio drawing; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
