3. Horizontal or Vertical patterns available

• Plate Aluminum Polishing:

2. Widths of 72" or more for #4 Brush finish
3. Horizontal or Vertical patterns available

• Tube and Pipe Aluminum Polishing:
1. Round or Square shapes
2. Brushed longitudinal finish for round shapes available

• Extrusions
• Die castings
• Sand castings
• Permanent mold castings
• Machined parts
• Fabricated parts
• Forgings

In our aluminum polishing, we reduce scrap - Our robot and automatic polishing processes use calculated material removal to reduce scrap caused by pitting, breakout or polishing error. Most castings have a very small layer of good material which is critical to find to produce good parts. Once the layer is broken, porosity continues to worsen. These automatic and robotic polishing processes create very consistent results.

Common finishes for aluminum polishing:
• Mirror: #7, #8
• Brushed: #4, #6
• Prep for paint or powder coat
• Prep for chrome
• Prep for anodize

In many cases, we provide a buffed finish prior to coating instead of the traditional belted finish. Through automation, we can offer great pricing and you start with a much higher quality surface. The smooth mirror surface allows you to easily inspect prior to the coating process with no grit lines to worry about showing through your coating.
