Understanding Metal Stamping Process: Definition, Advantages, Characteristics & Materials

Metal stamping is a process that uses punch and molds to deform or fracture iron, aluminum, copper, and other sheets and heterosexual materials to achieve a certain shape and size. Metal stamping is sometimes called sheet metal forming, but it is slightly different. The so-called plate forming refers to the use of plates, thin-walled tubes, and thin profiles as raw materials. The forming method of plastic processing is collectively referred to as plate forming. At this time, the deformation in the direction of the thick plate is generally not considered. The stamping industry involves a wide range of fields and goes deep into all aspects of the manufacturing industry. As for the metal stamping manufacturing process as a whole, the stamping process is mainly affected by three factors: equipment type, workpiece material, and lubricant performance. 

 

Advantages of metal stamping:

– Metal stamping parts are manufactured by stamping on the premise of low data consumption. Their parts have lightweight and have good stiffness. Moreover, after the sheet metal is plastically deformed, the internal arrangement structure of the metal is improved to improve the strength of the stamping parts.

– Metal stamping parts have high dimensional accuracy, uniform and common dimensions with modules, and have good interchangeability. The general device and application requirements can be satisfied without further machining.

– In the stamping process, because the appearance of the data is not damaged, it has good appearance quality and beautiful appearance lubrication, which provides convenient conditions for surface painting, electroplating, and other surface treatment.

 

Characteristics of metal stamping:

– High dimensional stability, lightweight and good stiffness

– Good surface quality and accuracy

– Easy operation with automation

– High productivity

– Mass production is available

– Low cost for high volume production

– Rely on equipment and mold

– Long production cycle and high initial investment

 

Applications of metal stamping:

– Automobile industry: such as wheel hub, gear, etc. are mainly deep drawing.

– Household industry: such as aluminum window, which is mainly formed by punching and shearing.

– Electrical industry: such as rice cooker, washing machine and other components.

– Daily use: make some handicrafts, such as tableware.

– Mobile phone industry: such as card slot, fixed frame, etc.

– Special stamping: such as stamping of aviation parts.
