When the 5052 aluminum plate is used for appearance parts, you will be very concerned about the appearance of the aluminum plate, and often some subtle problems will affect the overall effect.
The possible problems after oxidation of 5052 aluminum plate are: black silk, chromatic aberration, sand holes, etc.
1. There are many reasons for 5052 aluminum plate to produce black wire, such as the rolling oil dripped on the auxiliary machine due to poor management, and the indentation caused by excessive pressure or excessive tension on the plate surface. If it is rolled to thin material, these The dark marks will become thinner and thinner, forming dark lines or black lines, and sometimes it is difficult to tell whether it is oil or marks, or even no color difference can be seen on the surface, but it is very obvious after oxidation. For customers, if they see inconsistent appearance, they must refuse. The appearance of black silk after oxidation is the most fatal. Once this happens, there is almost no room for survival, and the losses and consequences brought about are irreparable.
2. Second, color difference. Generally speaking, color difference cannot appear in products made of appearance parts. Any customer is unwilling to accept products that are similar to "two leather faces". To eliminate these problems, it is still necessary to rely on the source machine to control them.
3. Reasons for sand holes: Sand holes are generally caused by internal structure problems, which are caused by factors such as impurities or water vapor not being removed, or other elements not being stirred evenly during ingot casting, so it is required to be in the source link of ingot casting. Control detection is good.
