Why should the surface of aluminum veneer be polished before spraying?

The grinding process is critical in the production of aluminum veneer. Smooth surfaces, neat angles, bright colors, and so on are commonly used to assess the appearance quality of aluminum veneer products. These are distinguishable with our own eyes. Details determine whether or not a project succeeds or fails. Through these details, we can also see the quality of the manufacturer's products.

The following are three functions of the manufacturer's grinding process:

1. Can quickly remove burrs, oil, dust, and other contaminants from the surface of an aluminum veneer substrate.

2. The surface of aluminum veneer formed by sheet metal processing typically has some angles and must be polished to achieve a flatter surface. Therefore, grinding can reduce the surface roughness of the sheet.

3. Enhance the adhesion of the coating. As the paint has poor adhesion on the too-smooth surface before spraying, grinding can enhance the adhesion of the coating.

The polishing process is critical to the appearance of individual aluminum plates, yet it is clear that the polishing process has a direct impact on the product's appearance. After obtaining the raw material for the aluminum sheet, the manufacturer must go through a variety of processing steps, such as scribing and tapping. It is unavoidable that the surface will be damaged throughout the procedure, and burrs will be left on the edges. It has a direct impact on the quality of aluminum veneer items if it is not polished.

Is it necessary to polish fluorocarbon aluminum veneer before spraying? Aluminum veneer polishing is a technical difficulty. Because conventional manufacturers do not accept these burrs in their goods, polishing is also required. As a result, each piece of fluorocarbon aluminum veneer must be polished, and the surface must be smooth so that the aluminum veneer's surface is not uneven.

What kind of aluminum veneer goods meet the appearance requirement? First and foremost, the aluminum veneer surface should be free of scars and wear signs. Second, the plate's curved edge should be flat and smooth, devoid of concave and convex traces as well as tooth shapes. The intersection line should be visible, the corner should be rounded, and the rounded corners should be even and smooth. Manufacturers should pay close attention to the quality of aluminum veneer products because it is evidence of enhancing the brand value of the company.
