Aluminum anodizing is a very common aluminum surface treatment process. The whole process can protect the aluminum material and add decorative effects to the color of the aluminum material. It can be roughly divided into three stages: before, during and after anodizing. Let's take a closer look. 1. Surface pretreatment before oxidation Use chemical or physical methods to clean the surface of the profile, exposing the pure substrate, in order to obtain a complete and dense artificial oxide film. Mirror or matt (matt) surfaces can also be obtained by mechanical means. 2. Anodizing the aluminium profile after surface pretreatment, under certain process conditions, oxidation occurs on the surface of the substrate to form a layer of dense, porous and strong adsorption AL2O3 film. 3. Sealing after anodizing Use a medium-temperature sealing agent to seal the pores of the porous oxide film formed after anodizing, so as to enhance the anti-pollution, corrosion resistance and wear resistance of the oxide film. The oxide film is colorless and transparent. Using the strong adsorption of the oxide film before sealing, some metal salts are adsorbed and deposited in the film pores, which can make the profile surface appear many colors other than the original color (silver white), such as: black, bronze, Golden yellow and stainless steel color, etc.

Now more and more people accept the green and environmentally friendly light steel housing, and more and more light steel villas have become the first choice for many people. The same green and environmentally friendly all-aluminum home is also favored by residents. After the popularity of light steel villas, why is all-aluminum home also popular? Advantages of all aluminum home 1. Environmentally friendly materials The aluminum alloy profile structure used for all-aluminum furniture has absolutely zero formaldehyde, and is a material that can be recycled and reused at a guaranteed price. 2. Waterproof All-aluminum furniture is made of all-aluminum alloy profiles. It is not afraid of water or moisture. It can be washed and cleaned directly with water, and it will never rot. This feature is mainly reflected in all aluminum cabinets and bathroom cabinets. 3. Fire prevention All-aluminum furniture has strong heat resistance, and tests have shown that it can withstand a temperature difference of 200°C without damage. Even if the whole piece is lit and placed on it, its surface will not be damaged after burning for a long time, which overcomes the disadvantage that ordinary boards cannot withstand burning. This feature is mainly reflected in the cabinet wall cabinet and the all-aluminum altar. 4. Anti-insect ant All-aluminum furniture is extremely hard and is not afraid of any pests, even termites. 5. Impact resistance All-aluminum furniture has strong impact resistance. The experiment proves that it can withstand the test of 227g steel ball falling from 3m without damage, and the bending strength reaches 150Mpa. Used under normal conditions, it can last for 50 years. 6. No smell All-aluminum furniture is processed from aluminum alloy profiles and plastic-steel connectors in a clean environment, and the products have no peculiar smell. 7. No deformation High-strength aluminum alloy profiles for all-aluminum furniture do not absorb moisture and have a small temperature expansion coefficient, so they will not deform. 8.Easy to clean All aluminum furniture can be washed with detergent and water, and it is easy to clean. 9.The edge is firm The aluminum profile structure of all-aluminum furniture does not have the problem of degumming and debonding, which is common for panel doors to be glued or thermally laminated. 10.Good durability The all-aluminum furniture meets the quality requirements of the outdoor curtain wall after surface treatment such as deep oxidation and spraying.

Aluminum doors and windows are composed of aluminum frames, center pillars, and fans. Compared to doors and windows made of other materials, aluminum doors and windows have greater advantages. 1. Light weight and high strength. Aluminum doors and windows are made of aluminum material with hollow core and thin-walled composite sections, which is convenient to use and reduces a lot of weight. It also makes installation more convenient, and the section also has very high bending strength. It is also very durable when used as doors and windows, and the possibility of deformation is very small. 2. Sealing performance of aluminum alloy doors and windows The sealing performance of doors and windows directly affects their functionality and consumption. The sealing performance includes four aspects: air-tightness, water tightness, insulation, and sound insulation. 3. The shape of aluminum doors and windows is very beautiful Aluminum alloy doors and windows can be customized and matched according to your preferences. The surface of aluminum alloy can present various colors after anodizing treatment. For example, champagne color, gray color, wood grain color, etc. The window frames can be made large, making the indoor lighting brighter, effectively enhancing the contrast between indoor and outdoor, and making the home more comfortable. 4. Aluminum doors and windows have very strong corrosion resistance The oxide layer of aluminum alloy is very resistant to fading, and the surface does not require painting, so it will not fall off and is easy to maintain. With the improvement of people's living standards and changes in social values such as taste and fashion, the functions of doors and windows will also become more convenient and powerful.

Aluminum profiles are manufactured from aluminum rods or plates through processes such as hot melting, extrusion, and coloring. Characteristics of industrial aluminum profiles Aluminum profiles have good corrosion resistance and their conductivity and thermal conductivity are better than copper. They are also non-ferromagnetic materials, making them more suitable for application in the electronic and electrical industry. However, Casting defect such as shrinkage cavity, sand hole, air hole and slag inclusion are easy to appear in the production process of aluminum alloy. The use of industrial aluminum profiles 1.Architecture: Insulated aluminum doors and windows, curtain wall aluminum profiles, etc. 2.Radiator: A radiator made of aluminum profiles, which can be used for cooling various power electronic equipment. 3.Industrial production and manufacturing: industrial aluminum profile accessories, automated mechanical equipment, assembly line conveyor belts, etc. 4.Automotive parts manufacturing: automotive luggage racks, doors, body, etc. 5.Furniture manufacturing: home decoration frames, all aluminum furniture, etc. 6.Solar photovoltaic profiles: Solar aluminum profiles, frames, brackets, etc. 7.Track lane structure: mainly used for manufacturing of rail vehicle body. 8.Decoration: Made of aluminum alloy frame, used for mounting various exhibitions or decorative paintings. 9.Medical equipment: production of stretcher frame, medical equipment, medical bed, etc. National standard for industrial aluminum profiles The national standard for industrial aluminum profiles is General Industrial Aluminum and Aluminum Alloy Extruded Shapes (GB/T6892-2006), but since this standard is lower than the standard for building aluminum profiles, industrial aluminum profiles are generally controlled by Aluminum Alloy Building Shapes (GB5237-2008).

The main steps of the melting and casting process include the melting of aluminum materials, preparation of molds, and injection, cooling, detaching the mold, etc.  Firstly, place the aluminum material in a furnace for melting. And then, the aluminum liquid is transported to the mold through pipelines. The mold is designed based on the shape and size of aluminum products. And it can be the single chamber or multi-chamber. And then, the molten aluminum liquid is injected. After entering the mold and allowing the aluminum liquid to cool and solidify, the finished products will be detached from the mold. The key to the melting and casting process of aluminum products lies in the design and manufacturing of molds. The design of the mold needs to be considered various factors such as the shape, size, and thickness of aluminum products, as well as the influence of aluminum liquid fluidity and solidification. To ensure the accuracy and durability of the mold, high-precision processing equipment and materials are of great importance.

Powder spraying is the process of spraying a powder coating on the surface of an aluminum alloy substrate through electrostatic action. The adhesion, weather resistance, peeling resistance, and UV resistance of its coating are strong, and the coating is dense, which is incomparable to general surface treatment of aluminum profiles. The spraying effect is superior to the painting process in terms of mechanical strength and aging resistance, and the cost is also lower than the same effect of painting.   The powder spraying process adopts green and environmentally friendly technology, which does not contain solvents or volatile toxic substances, does not pollute the environment, and the powder can be recycled. It has the characteristics of energy conservation, safety, and less pollution. The powder spraying aluminum profile has a service life of 30 years under normal conditions. Its surface coating does not fade, discolor, or crack within 5-10 years, with uniform film thickness. Its weather resistance and corrosion resistance are superior to ordinary aluminum materials.   Powder spraying process: vertical (horizontal) spraying process flowchart: loading → pre-treatment (chromization) → spraying → curing → falling off the frame Chromizing purpose: To generate a fine and stable chromium coating on the surface of aluminum materials. This film layer has certain wear resistance, corrosion resistance, and good adsorption ability, which improves the adhesion of the coating during painting. Solidification: Powder spraying undergoes high-temperature baking, leveling and solidification to form final coatings with varying effects; In powder spraying, the baking and solidify temperature and time of powder coatings play a decisive role in the solidify performance of the coating film. Therefore, it is necessary to undergo multiple tests and classify the sprayed objects reasonably to determine the number and arrangement of hanging parts, as well as the corresponding baking and curing temperature and time, in order to ensure the quality of the coated products.   Different ratios of powders have different visual effects to meet the personalized needs of customers. Powder sprayed aluminum profiles with rich colors, uniform colors, and high cost-effectiveness are increasingly widely used in China, and the application of fashionable and personalized spraying is increasing. Powder electrostatic sprayed aluminum profiles can be constructed with various decorative effects through color matching and coordination based on the spatial relationship between walls, aluminum, and glass. The diverse colors and appearance effects of powder spraying can meet the construction needs of buildings with different styles, providing designers with a broader design space.
