Aluminum profile 3 types of mechanical finishes before anodizing

Mechanical finish methods can give aluminum profiles several different types of surface texture – from rough or patterned to a mirror finish.

Here are the most popular 3 mechanical finishes for aluminum profiles before anodizing

1. Brushing

A brushed finish is cosmetically appealing and looks like stainless steel, brushing aluminum profiles.

Brushing is beneficial for blending extruded die lines and covering some imperfections.

It is available in a wide range of textures based on different brushing mesh wheels.

Aluminum profiles can be anodized in different colors or bright dipping anodizing after the brushing.

2. Polishing

Polishing gives aluminum profiles a smooth and shiny surface.

After going through the aluminum profile polishing machine, they come out with a significant specular reflection and mirror-like look, polishing aluminum profiles.

A soft cloth charged with abrasive grains is run over the extrusions to create this effect.

This process was called mechanical polishing.

For the mirror looks like aluminum profiles, which is the most important before chemical polishing.

3. Shot blasting/sandblasting

Blasting produces a unique granular appearance that can hide a lot of imperfections with a wide range of textures.

This type of mechanical finish is an outside operation with associated lead-time costs.

Some of these costs can be offset as bead blasting can cover up defects thus resulting in higher yields for each applied part.

Besides the above 3 major mechanical finishes, there are grinding, buffing, etc mechanical finishes for aluminum profiles, all belonging to mechanical finishes and that will make aluminum profiles more pattern and texture.
