At present, the classification of various aluminum plates used in industry is introduced in detail, and the manufacturing process of aluminum plates is explained. Today we mainly introduce the surface quality requirements of pure aluminum plates so that you can become familiar with the manufacturing process of aluminum plate surfaces.
The most basic point is that the surface of the circuit board must be clean and no cracks or other oxides are allowed.
Two: Indentations, scratches or rolling defects are allowed due to the imperfect process on the plate surface, but their absolute depth cannot exceed the allowable negative deviation of the sheet. Exceeding the compensation value will re-occur.
Three: The process of the aluminum plate allows the coating and the bubbles in the coating to be partially lost.
Four: Except for defects within the thickness range, the sheet metal surface can usually be repaired.
Five: Some other requirements are mainly set by suppliers and suppliers themselves, and then change the manufacturing process.
Aluminum plate surface quality requirements are key indicators to ensure the appearance and performance of aluminum plates. The following are some common aluminum plate surface quality requirements:
Surface smoothness: The surface of the aluminum plate should be flat and smooth, without obvious defects such as waves, unevenness, and wrinkles. Surface flatness not only affects the appearance of the aluminum plate, but is also directly related to its performance.
Surface cleanliness: The surface of the aluminum plate should be free of oil, dust, impurities and other pollutants. A clean surface helps maintain the original color and luster of the aluminum plate, while also preventing contaminants from causing corrosion and damage to the aluminum plate.
Surface color uniformity: The surface color of the aluminum plate should be uniform without obvious color difference. Color uniformity not only affects the appearance of the aluminum plate, but also ensures that the aluminum plate presents a consistent visual effect under different lights and angles.
Surface scratches and damage: There should be no obvious scratches, indentations, bumps and other damage on the surface of the aluminum plate. These damages not only affect the appearance of the aluminum plate, but may also reduce its mechanical strength and corrosion resistance.
