Polishing Process
From Scratch Grading to Final Inspection
A professional screen polishing line is not only one machine. It needs scratch grading, protection, matched consumables, correct timing and final quality control.
Grade the Screen

Protect the Device
Use suitable fixtures and protective glue when the screen polishing process requires protection.
Treat Deep Scratches
Use deep scratch treatment before final polishing for severe screen conditions.
Buff and Polish
Restore clarity, brightness and smooth surface appearance with matched powder and pads.
Inspect Results
Check finish quality and decide whether the screen can move to higher-value inventory.
Polishing Consumables
Consumables Matched to the Machine and Process
The polishing result depends on the complete system: machine settings, glue, pad, powder and operator process.
Protective Glue
Used to protect the phone and prepare the screen surface before polishing workflows.
