Aluminum disc or discs of various sizes and thicknesses are usually used to make products and more creative uses. Products made with aluminum rings include capacitors, medical tubes and kitchen utensils, and beverage cans.
A press is usually used to draw circles into various sizes. Capacitors use small pots, while aluminum kitchen utensils are larger. The size and thickness of the circle match the required size and thickness of the final product. Because aluminum has good ductility, aluminum is easier to draw into its final shape than other metals. Aluminum will not rust like steel, but aluminum will oxidize and is often coated to prevent this.
In other cases, alumina is ideal. For example, with a capacitor, it can be used as a thin electrical insulator. In some cases, aluminum rings are used to make pet and key tags in their original circular shape. These circles are not drawn, but are engraved or engraved with letters. Large and thick optical discs are another kind of optical discs used in different products. They can be cut with computer numerical control (CNC) equipment or forged into shapes such as gears or brackets. In addition to the above uses, aluminum rings have many other uses because they are very suitable for further production or direct use.
The production process starts with raw aluminum, which is melted and mixed with other metals in various proportions, or kept pure and cast. Finally, it is rolled into an aluminum sheet and then wound onto a spool. In some cases, the paper is cut into smaller loops for processing, but sometimes it is used as a whole sheet of paper. These aluminum plates pass through a blanking machine, which cuts the roll of material into circles. Then stack the discs to organize them.
The cut circles are annealed to soften the cut edges because the blanking process tends to harden the edges. Annealing is a heating and cooling process in which the metal is slowly cooled to eliminate internal stress. After the circle is cut and annealed, there will be scraps left in the plate, which will be recycled back into the process as raw materials. The cutting discs are stacked, packaged and sold to various factories to manufacture many of the above products. Large users of aluminum rings can choose to buy aluminum plates and perform the blanking process themselves. This has the cost advantage of buying plates, but because the scrap needs to be shipped back to the aluminum processing company, additional material handling is required to dispose of the scrap. In addition, although the aluminum disc itself is not complicated, the final product and production usually require some thinking.
