Green mold Surface Finishes
We provide finishes for aesthetics and performance: anodizing, polishing, sandblasting, coatings, and heat treatment. Let’s find the right one!
As Machined
This machined finish is rough and displays tool marks, representing the most basic form of surface treatment without any additional finishing or polishing.
Anodizing
It creates a protective oxide layer on aluminum, increasing corrosion resistance and hardness, and allowing for dyeing to enhance appearance.
Polishing
Polishing smooths surfaces to a high sheen, enhancing appearance and reducing roughness while offering some corrosion protection.
Brushed Finish
A brushed finish has fine, parallel lines for a textured look, enhancing grip and reducing fingerprints.
Sandblasting
Sandblasting uses high-pressure air and abrasive particles to clean or texture surfaces, enhancing adhesion for coatings.
Electropolish
Electropolishing is an electrochemical process that smooths and brightens metal surfaces, removing imperfections and enhancing corrosion resistance.
