PCABS Rail Transit Interior
Problem Phenomenon
[Problem Phenomenon] High-speed rail and subway interior parts require flame retardancy, low smoke, and impact resistance
Cause Analysis
Flame-retardant low-smoke PC/ABS meets rail transit standards such as EN45545; used in interior panels, air ducts, and seat components; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solution
Select low-smoke flame-retardant grades for rail parts; verify according to EN45545; prevent warpage for large-size parts; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Key Takeaway
PC/ABS rail interiors, low smoke and flame retardant, pass EN45545; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for similar problems in the future
