Metal finishing is important for a variety of reasons. Bright Dipping is a chemical pre-finish which produces an extremely high luster on aluminum. The bright dipping process is performed on raw product and before the anodizing process. It is a preferred method of pre-treatment for the
bulk anodize process as it creates a smoother surface on the part. The smoother the surface, the easier it is to secure the bulk fixture to obtain a better yield. And also helps improve the appearance when aesthetics are almost as important as a low price in automotive applications. While there are various types of anodizing that can be used to finish aluminum, one type of finishing process applicable across a variety of industries is bright dip anodizing.
Bright dip anodizing offers several distinct advantages over other types of surface treatment methods, making it a clear choice when cosmetic finishes are critical to your product. Let’s explore these benefits more closely to see why you should use bright dip anodizing on your aluminum components instead of other anodizing pre-treatment processes.
Bright dip anodizing is a chemical polishing process designed to brighten and embolden aluminum, usually to enhance the aesthetic of a metal part. It uses a combination of phosphoric and nitric acids, which level the roughness of the aluminum surface and help increase its specularity.
As a result, no deposits are left on the surface after treatment, which leads to a clean, attractive part that is smooth and better protected from scratching. Parts that are finished via bright dip anodizing are often brighter and can have a glossy appearance, depending on the type of anodize process assigned.
Because bright dip anodizing can help create such attractive end parts - and in various colors, to boot – they're often used to enhance aftermarket automotive parts and components, light reflectors, appliances, architectural features, sporting goods, and even industrial and military components, among others.
One of the biggest benefits associated with bright dip anodizing is the fact that when it's done correctly, it can significantly enhance part aesthetics due to its brightening ability. Parts finished via bright dip anodizing are glossy, smooth, and can be done in any color.
There are various other benefits to this part-finishing method as well:
The bright dip process is commonly used with aluminum metal parts, specifically alloys 2011, 2014, 2024, 5357, 5457, 5557, 6061, 6063, 6463, 7075 and others The more aluminum in the alloy of your part, the brighter it has the ability to be.
It's a metal finishing method applicable to industries that include automotive, medical, cosmetic applications, industrial components, and more. It can also be applied to safety-critical components and parts that require a high degree of reliability. And with the bright dip pre-treatment, typically the amount of material removed during this process is equivalent to the amount of coating put back on the part, so that tight tolerances are relatively unaffected.
It's also worth noting that not every finishing shop can perform a bright dip anodize service. It also tends to be a complex process, with the solution needing to be operated at a very specific temperature and contained in the appropriate environment for best results. Beyond all of this, there's a level of skill required for a successful end product as well.
