The blank aluminum discs is widely used in kitchenware, road signs, electronics because of low density, light weight, smooth surface, good extensibility and excellent electrical and thermal conductivity. Its surface treatment includes: sandblasting, polishing, wire drawing, electroplating and spraying.
1. Sandblasting
It makes use of the impact of high-speed sand flow to clean and roughen the metal surface, which can make the surface of the aluminum sheet circle obtain a certain degree of cleanliness and different roughness, and its mechanical properties improved.
2. Polishing
It uses mechanical, chemical or electrochemical methods to reduce the surface roughness of the workpiece to obtain a bright and smooth surface. The polishing process is mainly divided into: mechanical polishing, chemical polishing, and electrolytic polishing. This will bring the blank aluminum discs a fashion and high-end simplicity feeling.
3. Wire drawing
It is the manufacturing process of repeatedly scraping aluminum circles out of lines with sandpaper. This will will make the metal matte shine with fine luster with clear filament traces.
4. Highlight cutting
The diamond knives are reinforced on the high-speed rotating (generally 20,000 rpm) spindle of the fine-engraving machine to cut the parts, and a local highlight area is generated on the surface of the product.
5. Anodizing
Anodizing can not only solve the defects of aluminum surface such as hardness and wear resistance, but also prolong the service life of aluminum sheet circle and enhance its aesthetics. Anodized aluminum discs has been often the choice of high-end kitchenware manufacturers.
