PCABS Automotive Exterior Application
Sorun Belirtisi
[Problem Phenomenon] Rearview mirror housings, grilles, and pillar trims require weather resistance and appearance
Neden Analizi
Weather-resistant grade PC/ABS (containing UV stabilizer) is used for exterior parts; but its long-term sun exposure weather resistance is inferior to ASA/PMMA, and high-requirement parts need coating or weather-resistant alloys
Çözüm
Select weather-resistant grade PC/ABS with coating for exterior parts; evaluate ASA types for high sun exposure parts; verify by xenon lamp aging; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Temel Çıkarım
PC/ABS exterior parts require weather-resistant grade plus coating, and sun exposure parts should be selected carefully; 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
