Bright Dip anodizing is a chemical process that is used for the achievement of sparkling and almost mirror finish. The process is similar to chemical polishing. This technique is applied on aluminum to not only for aesthetics but also for lengthening the lifespan on the aluminum’s treated part.
Because the bright dipping technique comes in a broad range of colors, it is usually used to enhance products cosmetically. The products which can be artificially enhanced are:
Sporting and recreational products such as paintball guns, baseball bats, and flashlights are also goods that can be upgraded through the bright dipping process.
The polished dipping process involves two back to back processes. Bright dipping is the electro-brightening treatment that provides the aluminum a high luster and glossy look. While anodizing is the method that adds extra protection from fading, scratching, and, most importantly, corrosion.
Bright Dipping encompasses a solution of nitric and phosphoric acid that polishes microscopic roughness, changing the surface’s texture. Often, additives are used to the blend to enhance its brightening capability and to reduce nitrogen oxide fumes. Since this process evens out the tiniest surface irregularities and leveling the minutest valleys and peaks, the aluminum comes out with a highly reflective and enhanced sheen.
Anodizing encompasses dipping the aluminum in the electrolyte bath along with a cathode; a protective oxide layer is formed on the surface of the part, which is subject to treatment through passing an electric current through the bath. Due to the additional oxide layer, anodized aluminum has an extended period compared to non-anodized or untreated aluminum.
Anodizing through bright dipping has the following background:
Receptive metal to bright dip anodizing is aluminum alloy. Further, the brightness degree depends upon the alloy type together with the surface finish of the part. The alloys which are hard tempered produces high lusters. The below-mentioned aluminum alloys are suitable for bright dipping:
Many companies, sometimes an odd aluminum profile manufacturer, offer anodizing services. However, not all organizations have bright dip provisions due to the involvement of complex processes. The phosphoric-nitric acid solution should be functioned at a specified temperature and contained in a walled tank in the well-ventilated room.
To get the best anodizing service, you must contact the company who has obtained all one-stop source for every metal finishing requirement. The bright dipping service company must have developed CNC machining, metal fabrication and extrusion function.
