1.Factors Affecting the Plate Shape of Capacitor Plate Strip Plate shape is a very complex issue, and many factors influence it. A change in any condition during the production process will cause a change in the plate shape of the capacitor plate strip. Before discussing the issue of plate shape changes, let's introduce the concepts of plate [...]

During metal deformation, the deformation is non-uniform, and stress and residual stress exist within the deformed body. The core objective of all technical work in the rolling process of capacitor plate strips is to achieve uniform deformation of the rolled product as much as possible, eliminate the adverse effects of non-uniform deformation, and reduce residual stress. However, [...]

1.Determination of Rolling Speedand Capacitor Material Control With the development of rolling technology, rolling speeds are becoming increasingly faster. In the capacitor material control process, as the rolling speed increases, the oil film thickness increases due to the oil wedge effect (see Figure 1), while the rolling force and friction coefficient decrease (see Figure 2). Therefore, high-speed rolling can [...]

1.Metal Deformation in Capacitor Cold Rolling Deformation During rolling, metal undergoes plastic deformation under external force, resulting in dimensional changes in the height, width, and length of the rolled piece. These dimensional changes are also significant during the capacitor cold rolling deformation. The magnitude of this deformation is called the deformation index. Commonly used deformation indices are shown in [...]

1.Residual Stress in Capacitors Manufacturing Residual stress refers to the secondary stress remaining in the deformed body after the external force is removed during the XUANSN capacitors manufacturing process. Residual stress can be caused by deformation, uneven heating and cooling, and uneven microstructure transformation. Residual stress, corresponding to secondary stress, is also classified into first-type, second-type, [...]
