The Difference and Expensive Difference Between Aluminum Alloy Doors and Windows and How to Color Aluminum Profiles-WJW Aluminum Supplier Aluminum

The difference between aluminum alloy doors and windows is cheap and expensive.
1. Profile quality.
For aluminum alloy doors and windows, the quality of the profile has always been very important. The quality of the profile includes the thickness, strength, and the thickness of the surface oxidation film of the profile itself. It is also one of the main factors to open the price gap.
2. Select hardware.
Although the domestic door and window industry is developing rapidly, in terms of product hardware, domestic goods and foreign goods still have obvious quality gaps. Some domestic aluminum doors and window manufacturers have saved costs for aluminum. When making products, they will be produced. Choose domestic goods, and some mid -to -high -end brands will choose high -end imported hardware at the expense of cost. In this way, the production cost of two types of products will further open the gap, which will naturally affect the pricing of the finished product.
3. Differences in production level.
For exactly the same group of materials, if the level of production process is different, the finished products that are finally produced are often uneven, so those low -end and low -end aluminum alloy doors and windows often do not use more finely fine It is made from high -level technology, and high -end products with high aluminum materials will be excellent during production, and every detail strives to be perfect.
Before coloring aluminum profile, the aluminum profile must be oxidized and squeezed the aluminum alloy profile. And the appearance of appearance.
The main process is:.
(1) Surface pre -processing: Use chemical or physical methods to clean the surface of the profile to expose pure matrix to facilitate the obtaining complete, dense artificial oxide film. surface.
(2) anode oxidation: The profile that is prepared on the surface, under certain process conditions, anode oxidation occurs on the surface of the substrate, generates a layer of dense, porous, and strong absorption AL203 film layer.
(3) Seal the hole: Close the membrane pores of the porous oxidation film generated after anode oxidation, prevent pollution of the oxide film, enhance the resistance and wear resistance, and the oxide film is colorless and transparent. Strong attachment, adsorb some metal salt in the membrane hole, can make many colors other than the appearance (silver white), such as: black, bronze, golden yellow and stainless steel, etc., aluminum.
