PCABS Electroplating Decoration Application
Problem Phenomenon
[Problem Phenomenon] Automotive and home appliance decorative parts require metallic appearance and heat resistance
Cause Analysis
Electroplating-grade PC/ABS has good surface adhesion, and after chrome plating it has a metallic appearance and better heat resistance than electroplated ABS; widely used in grilles, door handles, and decorative strips; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solution
Select electroplating-grade PC/ABS for decorative parts; eliminate substrate surface defects; verify coating adhesion and thermal cycling; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Key Takeaway
Electroplated PC/ABS has metallic appearance and heat resistance, the main force for decorative parts; 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
