    The customer was an Australian company and ordered this 50 aluminum parts for their fluid system. The three different glossy colors of red, black and blue by painting only on the laser engraved letters and logo was the key point for this project. In addition, compared to the common aluminum anodizing, hard anodizing provided stronger abrasion and corrosion resistance, so this surface finishing was usually applied for inner mechanical parts with high abrasion resistance requirement.




Manufacturing Step By Step:

Step 1: CNC machining the aluminum part. Strong cutting capability of the CNC machine and reasonable cutting tool path controlled by the programming were the two crucial factors to get a quality machined part with tight tolerance and smooth surface, also the high milling productivity of fast material removal.

Step 2: CNC machined aluminum parts. The machined smooth surface reduced the hand sanding time or even didn't need it for removing the cutting lines, this not only saved the manufacturing time and cost, also ensured closer tolerance.
Step 3: Laser engraved and hard anodized aluminum parts. The hard anodizing finish not only removed the cutting lines well also increased the part's abrasion and corrosion resistance as well as its electric insulation performance.

Step 4: Three glossy colors of Red, Black and Blue painted on the laser engraved letters and logo. Different glossy colors painting on the one same side was the main challenge for this project, it required not only excellent painting capability and also the highly experienced surface finishing skills.
Step 5: Finished parts in packaging for delivery. Each part was quality checked and then carefully packaged by foam bag for safe transportation, then put them all in a custom wooden box for shipping by DHL Express, two days later, the parts arrived at customer's hands and worked fine for the fluid system in the testing.
