Surface Finishing Guide
Because we own the facility, we control the finishing queue. Each part is inspected on-site before shipping to ensure surface consistency and dimensional integrity across every batch.
01 / Mechanical Processes
As-Machined
Ra ≈ 3.2 μm
None (Standard)
The fastest option available. Parts are delivered with visible tool marks left by the milling or turning process. Ideal for internal brackets, initial prototyping, or parts that will undergo secondary processing elsewhere.
Bead Blast
Ra ≈ 1.6 μm
+1-2 Days
Fine glass beads are blasted at high pressure to create a uniform matte texture. This process effectively removes directional machining marks and provides a consistent base for anodizing. It is excellent for reducing glare on visible panels.
02 / Chemical & Protective
Anodizing Type II
MIL-A-8625
Clear, Black, Blue, Red
A chemical process that increases the natural oxide layer of aluminum parts. This provides significant corrosion resistance and allows for decorative coloring. Type II anodizing typically adds 0.5 to 1.0 mil of thickness to each surface.
Powder Coat
2.0 – 4.0 mils
Matte, Gloss, Textured
Applied electrostatically as a dry powder and then cured under heat. Powder coating is far more durable than standard paint, providing excellent impact resistance and a wide range of RAL color options for industrial branding.
