First understand the formation of aluminum profiles, that is, aluminum ingots are obtained through the three processes of casting, extrusion and surface treatment to obtain aluminum materials with different cross-sectional shapes. Aluminum ingot, commonly known as aluminum rod, is the most primitive material of all aluminum profiles. The length is 8-12 meters. There are four diameters of D90mm, D105mm, D120mm, and D178mm. The domestic conventional one is made of 6063.

1. Melting and casting is the first process of aluminum production, and the main processes are batching, smelting, and casting.

2. Extrusion is a method of profile forming. First, a mold is created through section design, and then the heated round cast rod is extruded from the mold by an extruder.

3. Surface treatment is the treatment of the surface of the profile. Generally, anodized aluminum is commonly used, which gives people the visual effect of sand surface, bright white and oxidation coloring.

The formed aluminum profile can be distinguished from four aspects: use, alloy composition, cross-section size, and surface treatment.

1. Generally, domestic industrial aluminum profiles are widely used, such as aluminum alloy shelves, workbenches, automatic assembly lines, etc. Their difference lies in the different cross-sectional shapes (different uses). But they are all produced by hot melt extrusion, and then some Accessories connect it.

2. The alloy composition can be divided into a variety of alloy grades of aluminum profiles. The difference between different grades is that the proportions of various metal components are different, mainly aluminum-magnesium-silicon.

3. There are many series of cross-section sizes. This time I mainly talk about industrial assembly line aluminum profiles. Commonly used are 20 series, 30 series, 40 series, 45 series, 50 series, 60 series, 80 series, 90 series, 100 series and so on. There is also a profiled material, which is mainly processed according to the actual drawings of the customer.
