OEM Metal CNC Machined Milling Aluminum Parts With Anodizing Precision

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.

Design Consideration for Milling:

When designing parts to be CNC milled, there are several tips to keep in mind:

(1)CNC milling machines are capable of precision so try to use this to your advantage

(2)Avoid deep pockets which are difficult to machine

(3)Sharp inside corners are often difficult so consider using a radius

(4)Apply chamfers to the top edges to reduce sharpness and improve appearance.

(5)Apply filters to the bottom of pockets to reduce the possibility of stress fractures if the component is under stress.

(6)Thin walls and other flimsy shapes can be difficult to machine as they may not hold up against the pressure of the cutting action.

(7)Try to create shapes that do not have complex curves in more than one axis – as it may be difficult to hold during machining.

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.
