The term anodizing sounds very crude and highly specialized, not lifelike at all. But when we talk about mobile phone casings and cans, you must be familiar with them. You must have seen the colorful aluminum plates on the outer surfaces of many high-rise buildings! First of all, the phone cases and cans are brightly colored and pleasing to the eye and you will love them. Secondly, the mobile phone has been held in the hand, often corroded by sweat and friction, but still does not fade, bright as new, wear-resistant! This is the two major characteristics of the anodizing process!
What Is Anodizing
Anodizing is a critical step in the production of aluminum CNC machined parts. Anodizing is an electrochemical process that involves coating a metal part with an oxide surface layer. It adds sturdiness and a more appealing finish to the part. While aluminum is the most commonly anodized substrate, magnesium and titanium can also be anodized. Anodizing ensures that a part can withstand corrosion and wear and tear from prolonged use while also maintaining its cosmetic appearance under all conditions. In many cases, manufacturers send parts to a third-party anodizing service provider, similar to how heat treatment, tempering, or electroplating are handled.
Features of Anodizing
The principle of anodizing is that there is an endogenous metal oxide film on the outer surface of the metal, just like a transparent mobile phone film, which can not only reveal the luster of the metal, but also has a soft light, which can bring out the atmosphere and elegance of the product. It has several major features:
1. Corrosion and wear resistance.
2 . Good decoration, colorful.
3. Good stain resistance, no fingerprints, no stains, no fingerprints.
4. No paint, no chemicals, high fire resistance, no toxic gas at high temperature.
5. Good insulation, non-conductive.
It is widely used in exterior wall panels, electrical and electronic panels, metal panels for cabinets and kitchenware, metal ceiling panels, aerospace metal panels, parts and other places.
Why Choose Anodized Surface Film for Fingerprint Locks
First of all, the fingerprint lock is a facade project of a family, and it needs a good decorative product, so it cannot lose face; secondly, as a product that needs to be touched and pulled by hand every day, sweat corrosion and friction are unavoidable. , needs a good protective film; the surface anodizing process fingerprint lock feels as warm as jade in the hand, the metal in everyone’s imagination should be cold and stiff, but this process is to allow the metal to grow a layer of oxide film by itself (Think about the texture of the phone film in seconds)! So it’s neither cold nor stiff, but it doesn’t feel as woody as a cell phone film! This oxide film is a natural “mobile phone film” of metal, which not only plays a protective role, but because the oxide film is transparent, the texture of the metal is revealed from the oxide film! Gives a light metallic sheen!
The new surface anodizing process is greener and healthier, with good corrosion resistance, salt spray resistance, no rust, no foaming, no peeling and peeling. The endogenous oxide film is not easy to change color, and the fingerprint does not remain, which improves the compactness, is more wear-resistant, scratch-resistant, and has higher strength.
As a security product for thousands of households, the fingerprint lock is fireproof, insulating, and does not produce toxic gas insulation, which can help the security effect. Most fingerprint lock products are manufactured by traditional processes such as electroplating or plastic. The environmental protection effect, decoration, and performance parameters are far lower than the anodizing process and will be replaced by more and more anodizing processes in the future.
