As a well-known brand in the industry, Yongxing aluminum profiles have been well received by users, and the key is quality. From the material quality, tolerance requirements and surface technology of aluminum profiles, we have been planning high-standard, strict-demand industrial production lines. The various aluminum profiles that appear on the market are of varying quality and at different prices. How should customers choose? The small series of Vietnam Yongxing Aluminum Industry Co., Ltd. can simply tell you to look at the quality and cost-effectiveness.
So, how does Yongxing Aluminum judge the quality?
The aluminum alloy is composed of elements such as aluminum, silicon, and magnesium. Each element has a specific content standard. Magnesium is expensive, and some manufacturers reduce the amount of expensive elements to a minimum or below the standard range, thereby saving costs. Even some manufacturers mix waste aluminum into materials, and sometimes it is estimated that there are many harmful ingredients, and these ingredients are not 6063 or other brands at all. Finally, the mechanical strength of aluminum products is reduced, and the difference in the price of aluminum profiles is not surprising. Formulations of various alloys of aluminum alloys produced by regular manufacturers can ensure that the content of each element is within the specified range, and the requirements are very strict. Each of them has their own data and they are kept secret. Qualified formula can guarantee the quality of the profile, otherwise, no matter how it is processed, it can not meet the requirements.
The melting and casting of aluminum rods is also very important. At present, domestic melting furnaces, in the 1940s, have the most primitive furnaces of the 1990s, but also have melting furnaces such as coal, steam, oil and electric heating, chimneys or chimneys without chimneys. Under normal circumstances, no matter what kind of fuel is used in the melting furnace and the casting furnace, the chimney should be used. Otherwise, the exhaust gas and the slag will be dissolved in the aluminum water, and the slag package will inevitably occur. Manufacturers with high product requirements should be equipped with homogenization equipment. In the process of smelting and casting, various trace elements can be evenly distributed to ensure the quality of the final Yongxing aluminum.
In order to enhance the protection of the aluminum profile substrate, some surface treatment is usually performed. Different surface treatment film thicknesses have certain differences according to actual needs. The film thickness units are generally expressed in μm (micrometers), and are usually abbreviated as μ. The thickness of several commonly used surface treatment films of Yongxing Aluminum in Vietnam is described as follows:
1. Aluminum alloy anodized surface treatment film thickness:
According to the application requirements, the thickness of the surface oxide film of the aluminum profile is mainly divided into four grades. The average surface film thickness of Vietnam Yongxing aluminum alloy profiles is 10μm, 15μm, 20μm and 25μm, respectively, and the local content is not less than 8μm, 12μm, 16μm and 20μm, respectively.
2. Surface treatment film thickness of aluminum alloy powder coating: The film thickness of aluminum alloy powder sprayed surface coating is generally not classified, the average film thickness is not less than 40 μm, and the local film thickness is not less than 35 μm.
3. Fluorocarbon sprayed aluminum alloy Vietnam Yongxing aluminum surface treatment film thickness:
The film thickness of aluminum alloy fluorocarbon sprayed surface is usually divided into two types: 2 coating 1 baking, 3 coating 2 drying, 2 coating average film thickness 30μm, 3 coating average film thickness 40μm, local film thickness not less than 25μm And 34μm.
The basic processes for the anodizing treatment of Yongxing aluminum materials are: surface cleaning, anodizing, coloring and sealing.
Surface pretreatment is mainly used to eliminate grease, impurities and the like on the surface of aluminum profiles. Generally, after several steps of degreasing (degreasing), caustic washing, neutralization, and water washing, polishing may be performed if necessary. Degreasing generally uses 4% ≤ 10% sodium hydroxide solution to remove impurities and suspended ash. Neutralization is generally carried out by acid leaching with sulfuric acid or nitric acid, first with cold water or hot water, and then with cold water for secondary cleaning. After surface pretreatment, a formal anodization process can be entered.
Film thickness of Yongxing aluminum surface treatment:
The film thickness of the aluminum electrophoresis surface is generally classified into three grades: A, B, and S.
Grade A: 12 μm oxide film + 9 μm electrophoresis film, the thickness of the composite film is not less than 21 μm.
Grade B: 9 μm oxide film + 7 μm electrophoresis film, the thickness of the composite film is not less than 16 μm.
S grade: 6 μm oxide film + 15 μm electrophoresis film, the thickness of the composite film is not less than 21 μm.
Of course, customers can negotiate the film thickness with Yongxing aluminum manufacturers according to the actual needs, so that the use of aluminum profiles is more targeted. Generally speaking, the thicker the film thickness, the better the protection of the aluminum substrate.
Share: Industrial aluminum profile frame customization process
The price of industrial aluminum profiles on the market is transparent, but many of the custom-made processes for industrial aluminum profiles are unclear. That is to say, when you customize the aluminum profile frame in an aluminum profile manufacturer, the delivery cycle is often extended because the process is unfamiliar. So today, Xiaobian will introduce to you the process of customizing the industrial aluminum profile frame for aluminum profiles manufacturers.
First, you need to tell the aluminum profile manufacturer your specific requirements and dimensions, or you can send a simple sketch to the aluminum profile manufacturer.
Second, the technicians of the aluminum profile manufacturer will communicate with the specific details according to your requirements or drawings, or go to the site for measurement.
Third, according to the data of communication or on-site measurement, aluminum profile manufacturers will give you scientific solutions, including the drawing of aluminum profile frame drawings, the selection of aluminum profile frame connection methods, and the aluminum profile specifications used for aluminum profile frames.
Workshop protection barrier
Fourth, according to the plan, the aluminum profile cutting, tapping, drilling and other deep processing services.
The fifth is to package and ship the processed aluminum profiles, or assemble the finished products for delivery. We can provide on-site installation instructions or video installation instructions.
