Metal Stamping Process Characteristics

Metal punching is a forming process that involves applying external force to sheets, strips, pipes, and profiles using a punch press and die in order to achieve the desired shape and size of the workpiece through plastic deformation or separation. What are the characteristics of metal stamping?

What is  metal punching?

Metal punching is a highly efficient and stable metalworking method, which is useful for processing strong and rigid parts. Metal stamping is based on metal plastic deformation, and employs molds and stamping equipment to apply pressure to the sheet, causing plastic deformation or separation, thereby obtaining parts (stamped parts) with certain shapes, sizes, and properties.

Metal stamping has the characteristics of thinness, uniformity, lightness, and strength, compared to castings and forgings. Stamping can produce parts with reinforcing ribs, ribs, undulations, or flanges that are difficult to manufacture using other methods to improve rigidity. Using precision molds, the accuracy of the workpiece can reach the micron level, with high repeatability and consistent specifications, to produce punched holes, pits, and convex shapes.

Characteristics of  metal punching

• Metal stamping is a high-efficiency and low-material-consumption processing method. The stamping process is suitable for the production of large quantities of parts, making it easy to achieve mechanization and automation, resulting in high production efficiency. At the same time, stamping production can minimize waste or achieve zero-waste production. Even in certain situations where there are margin materials, they can be fully utilized.

• The operational technology is easy, and the operator does not require a high degree of skill.

• Stamped parts generally do not require further machining and have high dimensional accuracy.

• Stamped parts have good interchangeability. Stamping has good stability, and the same batch of stamped parts can be exchanged and used without affecting assembly and product performance.

• As stamped parts are made of sheet material, their surface quality is good, which provides convenient conditions for subsequent surface treatment processes (such as electroplating and painting).

• Stamping can produce parts that are strong, rigid, and lightweight.

• Stamped parts produced with molds have low production costs.

• Stamping can manufacture complex-shaped parts that are difficult to make with other metalworking methods.

These are the characteristics of metal stamping. With the continuous improvement of stamping technology, modern stamping technology can effectively protect stamping dies, greatly improve production efficiency, and extend the equipment's service life, thereby gaining more recognition from corporate clients. During the rapid development of industry, stamping technology is advancing towards multifunctionality and automation.
