Anodizing Options for CNC Machined Aluminum Parts

●Anodizing is one of the most common finishing options, offering strong corrosion protection and enhancing the overall appearance of metal parts. Three types of aluminum anodizing are available from Protolabs:

●Type I-Chromic Acid: Provides a whisper-thin but still durable coating. Commonly used for welded parts and assemblies and as a primer before painting. Like all anodized surfaces, it is non-conductive.

●Type II-Sulfuric Acid: Harder than Type I it offers an exceedingly durable finish. Usage examples include carabiner hooks, flashlight handles, motorcycle parts, and hydraulic valve bodies.

●Type III-Hard Anodize or Hardcoat: This is the thickest and hardest anodize available and has a wide range of applications for parts and products in automotive, aerospace, heavy equipment, marine industry, general manufacturing, and military/law enforcement.

Advantages of CNC Milling:

CNC milling has a number of advantages over other manufacturing processes. Can produce quality parts of almost any shape or form Cost-effective machining for prototyping and short runs High dimensional tolerances are possible Smooth finishes can be achieved Can produce identical parts repeatedly Milling machines can operate at high speeds, producing parts quickly. A single machine can produce a wide variety of part shapes and sizes milling can be applied to many materials, including metals, plastics, and composites.CNC machines can be programmed using computer-aided design (CAD) software, which makes it easy to create and change designs.

FAQ:

Q: What's the MOQ?

We can accept low quantities.

Q: Can I get a sample for the check?

Yes, just need the sample cost, and we will return it back in mass production.

Q: What if I want custom a part but I can't draw?

We can also offer design services as long as you tell us all your requirements.

Q: I want to keep our design secret, can we sign an NDA?

Sure, we can sign the NDA before you send the drawing.

Q: How do you ship the goods and how long does it take to arrive?
A: We usually ship by DHL, UPS, FedEx or TNT. It usually takes 3-5 days to arrive. Airline and sea shipping is also optional.

Q: How to proceed with an order?
A: Firstly let us know your requirements or application. Secondly, we quote according to your requirements or our suggestions. Thirdly customer confirms the samples and places a deposit for a formal order. Finally, we arrange the production.

Q: Do the products of all the colors are the same with the same surface treatment?
A: No. about powder coating, the bright color will be higher than white or gray. About the Anodizing, colorful will be higher than silver, and black higher than colorful.
