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.

FAQ:
Q: How to avoid mass order quality problems?
A: Strengthen the prevention and inspection in advance of the process of production and processing, set important processes as the key point of quality control, and follow up the inspection and defense throughout the process.
Q: How many checks are performed on a project?
A: Usually, products will go through the following four inspections: incoming inspection, production first inspection, sampling inspection, and pre-shipment inspection. Among them, sampling inspection will be conducted multiple times.
Q: Will you be able to work with our engineering team to review drawings and provide quick, estimated pricing for desired changes?
A: Yes, our engineers respond very quickly. If there is anything to be modified in the product, we can offer you a new price as soon as you tell us.
