Principle

Aluminum Polishing Methods
Different post-CNC polishing techniques achieve specific surface outcomes:

Mechanical Polishing
Uses abrasive tools (wheels, belts, pads) to physically smooth surfaces. Ideal for:
• Removing machining marks
• Creating consistent grain/mirror finishes
• Preparing parts for anodizing/coating

Chemical Polishing
Applies chemical solutions to etch and smooth surfaces. Suitable for:
• Intricate/delicate parts incompatible with mechanical polishing
• Achieving uniform finishes on complex geometries

Electropolishing
Electrochemical process removing microscopic surface layers. Benefits include:
• Superior surface smoothness and cleanliness
• Enhanced corrosion resistance
• Medical, aerospace, and cleanroom applications

Vibratory/Tumbling Polishing
Vibrates/rotates parts with abrasive media. Best for:
• Batch processing of small components
• Edge deburring and smoothing
• Creating satin/matte finishes

Technical Parameters

PACKING

Packing Process
Our packaging combines EPE foam and Kraft paper:

Interior Protection: EPE foam safeguards aluminum profiles against impact damage

Exterior Protection: Kraft paper shields against moisture while ensuring package integrity
