  The aluminum profile industry has become a very mature industry. The aluminum density is only 2.7g/cm. Although it is soft, it can be made into duralumin, hard aluminum, rust-proof aluminum, cast aluminum and other aluminum alloys. Nowadays, the application of aluminum housing is very extensive, let us see how to judge the quality of aluminum housing? 1. The text on the surface of the aluminum shell material is generally printed with imported inkjet codes. The text is clear, and the trademark identification, manufacturer, address, telephone, etc. are generally clearly marked. The text on the surface of the real fake aluminum veneer material is mostly printed by ordinary printing machines. Blur, its manufacturer, display etc. 2. The aluminum outer packaging material is made of high-quality raw materials, with high technical precision, and the surface and inner layers feel smooth and even. 3. The wall thickness of the aluminum shell is uniform, the aluminum veneer material is tight...

  With the development of society and the advancement of technology, equipment manufacturers have higher and higher requirements for the internal quality and appearance of aluminum alloy shell parts. In order to meet the ever-increasing internal quality and appearance requirements, manufacturers have adopted various methods to improve the internal and external quality of aluminum alloy shell parts. In production practice, the external quality of aluminum alloy parts is often improved by anodizing surface treatment process. After anodizing treatment, a layer of anodic oxide film with a certain thickness, strength and beautiful appearance can be formed on the surface of the aluminum alloy shell parts. Through electron microscope observation, it can be found that the structure of the anodic oxide film is honeycomb, and the center has a micropore that grows perpendicular to the surface of the aluminum substrate, showing the beauty of the shape that cannot be seen in other surface treat...
