Aluminum Hard Anodized and Painted Parts

Project Overview:

Manufacturing Process: CNC Machining
Material: Aluminum 6061-T6
Surface Finishing: Laser Engraving, Hard Anodizing, Glossy Painting
Manufacturing Tolerance: ± 0.05 mm
Quantity: 50 Pieces
Lead Time: 12 Days

The customer was from Australia and ordered this 50 aluminum parts for their fluid system. Painting three glossy colors in Red, Black and Blue on laser engraved Logo & Text was the challenge of this project. Compared to common anodizing, hard anodizing provided much stronger abrasion and corrosion resistance, so it was usually applied for mechanical parts.
Manufacturing Step By Step:

CNC machining aluminum parts. Strong cutting capability got the aluminum parts milled at tight tolerance, smooth milled surface and the milling time as short as possible. An ABS fixture was used to assist the aluminum milling.
 CNC Aluminum Prototyping CNC Aluminum Prototype
CNC Milled PartsCNC milled aluminum parts. The smooth milled surface reduced or even eliminated the hands sanding to remove cutting lines, which considerably saved the production time and cost.
Aluminum Hard Anodized PartsThe M8 tapped, Logo laser engraved and hard anodized parts. Hard anodizing improved the surface smoothness by removing the minor cutting marks as well as the surface adhesion to other coatings.
Hard Anodized Aluminum PrototypesThree glossy colors painted in Red, Black and Blue on the Logo. Painting different colors on one same surface was a challenge, which required excellent painting capability as well as finishing experience.
Hard Anodized Aluminum PartsPackaging the parts for delivery. Each part was carefully quality checked and then packaged by a foam bag for safe transportation.
