Anodizing Precision Machining Components at Worthy Hardware.

With over 20 years of experience manufacturing precision parts, we consider anodizing a reliable, economical and proven finishing process for aluminum components. Worthy Hardware uses a network of qualified partners to provide anodizing finishes to our client projects.

Available colors include clear, yellow, green, red, and black....

Then most of our customers ask”what is anodzing” and” why we need to anodize precision machining parts “.

What is Anodizing?

Anodizing is an electrochemical process that converts the metal surface into a decorative, durable, corrosion-resistant, anodic oxide finish. Aluminum is ideally suited to anodizing, although other nonferrous metals, such as magnesium and titanium, also can be anodized.

The anodic oxide structure originates from the aluminum substrate and is composed entirely of aluminum oxide. This aluminum oxide is not applied to the surface like paint or plating, but is fully integrated with the underlying aluminum substrate, so it cannot chip or peel. It has a highly ordered, porous structure that allows for secondary processes such as coloring and sealing.

Anodizing is accomplished by immersing the aluminum into an acid electrolyte bath and passing an electric current through the medium. A cathode is mounted to the inside of the anodizing tank; the aluminum acts as an anode, so that oxygen ions are released from the electrolyte to combine with the aluminum atoms at the surface of the part being anodized. Anodizing is, therefore, a matter of highly controlled oxidation the enhancement of a naturally occurring phenomenon.

 Why we need to anodize precision machining parts?

·         Durability: As mentioned above, anodization changes the aluminum substrate at the molecular level. Anodized parts will not chip, flake or flake, and have extremely strong corrosion resistance and wear resistance. If sealed properly, wait at least five years in outdoor conditions.

·         Low Cost: High value. The service life of anodized aluminum parts is longer than its sprayed or plated similar parts, and the manufacturing cost is lower.

·         Safe for the Environment: Unlike spray coating and electroplating, anodizing does not produce hazardous waste or interfere with the recyclability of aluminum.

·         Easy to Maintain: The parts look original from production and have remained in this condition for many years. Soap and water or mild detergents can remove dirt and restore the finish relatively easily.

·         Aesthetics: The precision-processed parts are anodized to preserve the metallic luster of the parts, and the color is easy to repeat, which can be used in future production.

·         Improve lubrication: For internal components, the porosity of the unsealed anodized surface can improve the adhesion and lubricity of the adhesive. However, this may expose them to contaminants, and unsealed or partially sealed parts require special attention and consideration.

At Worthy Hardware, all CNC machining parts are subject to rigorous inspection and quality assurance, according to the specification required for the project which keeps your anodized parts looking their best for years on-end. Some of the considerations for providing a quotation will be:

·         Metal type

·         Alloy, temper, and finish desired

·         Anodizing specification/requirement

·         Color considerations

·         Special packaging and protective treatment

·         Production quantities

·         Testing and certification requirements
