PPO High-Gloss Grade Surface Maintenance
Fenómeno del problema
[Problem Phenomenon] Scratches on PPO high-gloss appearance parts and mold replication decay
Análisis de la causa
PS modification in MPPO slightly reduces gloss, and high-gloss parts depend on the mold surface condition; mold wear and contamination are directly transferred to the product; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solución
Regularly polish and maintain the mold for high-gloss parts; prevent scratches and contamination during molding; select high-gloss grades when gloss requirements are extreme; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Conclusión clave
The face of PPO high-gloss parts lies in the mold, and polishing maintenance is routine homework; after confirming effectiveness, solidify 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
