[China Aluminum Industry Network] Aluminum products are widely used in the automotive and construction industries. Improving the quality of aluminum products is fundamental to the survival of enterprises. Aluminum materials are extremely unstable in the air and are easily generated by the naked eye. Oxide film. Due to the different processing methods of aluminum parts, such as casting molding, direct shearing of sheet metal, or mechanical fine processing, or heat treatment or welding after forming by different processes, the surface of the workpiece will be presented. Different conditions, different levels of dirt or traces, for this purpose in the pre-treatment process must be based on the actual situation of the workpiece surface to select the pre-treatment process.

In the pretreatment process, it should be noted that not all surfaces of the cast molded part are mechanically processed, and excessively thick oxide layers formed in the cast process are left on the unmachined surface, and some sand layers are also sandwiched. The machine should be used first. The method of processing or sandblasting first removes the original oxide film of this part, or after alkaline cleaning and then processing, only in this way can not only remove the original oxide layer of the unprocessed part, but also avoid the tolerance dimension change of the machining part.
Matters needing attention in the pre-processing process of the fine-worked parts: Although the natural oxide film on the surface of the fine-worked parts is formed and easy to remove, the greasy weight, especially in and around the hole, must first pass through the organic solvent. Cleaning, if directly washed with alkali not only greasy weight is difficult to remove the net, and the fine processing surface can not withstand a long period of strong alkali corrosion, the result will also affect the roughness of the workpiece surface and the tolerance of the match, compared to the end may become waste.
