Aluminum profile automation equipment is specially used to produce and process industrial aluminum profiles. After oxidation treatment, the surface of industrial aluminum profiles produced by aluminum profile manufacturers is very smooth and beautiful, and such industrial aluminum profiles are also widely used in various fields. However, many friends have seen this situation in the process of applying industrial aluminum profiles, that is, the surface of aluminum profiles has become rough, and once its surface has a rough feeling, it will affect the appearance experience of aluminum profiles! Therefore, we must know what is the reason behind the surface roughness of industrial aluminum profiles.

The surface roughness of industrial aluminum alloy profile after chemical polishing may be caused by this defect, the high proportion of nitric acid in bath solution and acid erosion, and the surface roughness may be caused by internal tissue defects of aluminum. The specific tensile strength, yield strength, ductility and corresponding work hardening rate of aluminum profiles dominate the change of allowable deformation.

If the copper content in the bath is also high, the surface roughness will be more serious. Usually, if the nitric acid content in the bath solution is too high, the chemical polishing will react violently and there will be a "boiling" phenomenon. If the nitric acid content is normal and the copper content is high, a layer of obvious characteristic color of metallic copper is attached to the surface of the washed industrial aluminum alloy profile. If the characteristic color of copper is deep, the copper content in the surface bath is high, and measures should be taken to adjust the contents of nitric acid and copper to the normal range. If the additive contains copper, it should be added less appropriately; If the copper in the bath comes from the chemical polishing of copper-containing aluminum, measures should be taken to add copper-free additives or adjust the bath.

If the surface of industrial aluminum alloy profile is rough due to internal structure defects: as-cast structure, such as cast or die-cast aluminum workpiece; Defects such as insufficient grain refinement, looseness and slag inclusion of aluminum material; The surface roughness caused by defects such as insufficient deformation and pine-like patterns in the processing process can be prevented by improving the internal quality of industrial aluminum alloy profiles.

Industrial aluminum profiles can realize continuous high-speed stamping and are convenient to be directly processed into products.

Industrial aluminum profiles are favored by many enterprises because of their excellent performance! The aluminum products processed by industrial aluminum profiles are very beautiful and generous in appearance, but also very resistant to dirt, not easily corroded or rusted, and very convenient to clean! In addition, industrial aluminum profiles do not need to use welding technology in the processing process, which is more environmentally friendly than other materials! But now there are so many manufacturers producing industrial aluminum profiles on the market, how can we ensure that the manufacturers we choose are superior in all aspects?

Industrial aluminum profiles have good processability, and the positive alumina veneer has strong decoration and moderate hardness. It can be easily bent and formed to realize continuous high-speed stamping and facilitate direct processing into products. Without complicated surface treatment, the product can be greatly shortened. Production cycle and reduced production cost. In recent years, the number of aluminum profile manufacturers is also large, which is inevitably mixed together, so we should balance the choice and choose a good manufacturer in the purchase process.

Superior industrial aluminum profile manufacturers have a set of processes in product development, production and manufacturing. Exquisite technology and high-quality products have won the recognition of customers.
