What is the forming process of Aluminium Circle 1000 series?

The high purity and excellent physical properties of Aluminium Circle 1000 series have been widely used in various industries. Its forming process is a key link to ensure product quality and performance. The forming process of 1000 series aluminum circles will be described in detail below.

1. Raw material preparation
The first step in the forming process is the preparation of raw materials. 1000 series aluminum circles mainly use high-purity aluminum ingots as raw materials. The chemical composition of the aluminum ingots must meet the corresponding standards to ensure that the purity of aluminum reaches more than 99%. The selection of materials is crucial. Suitable raw materials can improve the performance of the finished product and reduce the generation of waste in subsequent processing.

In the preparation stage, the aluminum ingots need to be cleaned to remove oxides and impurities on the surface. This process helps to improve the efficiency of subsequent processing and the quality of the finished product.

2. Heat treatment
After cleaning, the aluminum ingots usually need to be heat treated. The purpose of heat treatment is to improve the organizational structure of aluminum and make it easier to form in subsequent rolling and stamping processes. The specific temperature and time of heat treatment are adjusted according to the specifications and forming requirements of the aluminum ingot.
After heat treatment, the aluminum ingot will soften, so that it can better withstand stress during rolling and stamping, thereby avoiding cracks and deformation. This link is one of the key factors to ensure the quality of aluminum disc forming.

3. Rolling
After the heat treatment is completed, the aluminum ingot enters the rolling process. Rolling is divided into hot rolling and cold rolling. The specific choice depends on the requirements of the finished product and subsequent applications.
Hot rolling: rolling at high temperature, mainly used for the initial forming of aluminum ingots. Hot rolling can effectively reduce the yield strength of aluminum, making it easier to shape, and is usually used to make thicker aluminum plates.
Cold rolling: rolling at room temperature, used to further thin the aluminum plate and improve its surface quality and mechanical properties. During the cold rolling process, the aluminum sheet will undergo multiple rolling to achieve the required thickness and width.
The rolled aluminum sheet is usually cut into the required size by shearing to prepare for subsequent stamping.

4. Stamping
Stamping is the most important step in the forming process of aluminum discs. After rolling, the aluminum sheets will be fed into the stamping machine for punching and cutting to form standard aluminum discs. The stamping process involves multiple steps, including positioning, punching and unloading.
Positioning: Before stamping, the aluminum sheets need to be accurately positioned to ensure that the size and shape of each aluminum disc are consistent. The positioning device usually includes a clamp and a guide device.
Punching: The aluminum sheet is cut into a circle by applying pressure through the punch of the stamping machine. The speed and pressure of punching need to be adjusted according to the thickness and material of the aluminum sheet to ensure that the cut is smooth and burr-free.
Unloading: After stamping, the aluminum discs will be collected by the automatic unloading device for subsequent processing.

5. Surface treatment and inspection
After stamping, the aluminum discs usually need to be surface treated, such as cleaning, deoxidation film and coating. This process can improve the appearance quality of the aluminum discs, and also enhance their corrosion resistance and service life.
After surface treatment, aluminum discs need to undergo rigorous inspection to ensure that their size, thickness, appearance and other indicators meet the standards. Common inspection methods include visual inspection, measurement and laboratory testing.
