What stamped parts？
Stamped Parts-Stamping is a forming process that relies on presses and dies to apply external forces to materials such as plates, strips, tubes and profiles to produce plastic deformation or separation to obtain workpieces of the required shape and size (stamped parts). The blanks for stamping are mainly hot-rolled and cold-rolled steel plates and strips. Thanks to the use of precision dies, workpieces can be produced with micron-level precision and with high repeatability and uniformity of specifications, allowing for the stamping of holes and bosses, etc.
Stamped parts are generally commonly used in various industries such as automotive, aerospace and medical to provide a variety of customised parts. Stamped metal parts are an effective and affordable way to meet the requirements for high volume manufacturing of customised metal parts, which typically meet the requirements of:
What is the use of stamping parts?
Hardware stamping parts are used in many products in modern society and in various industries, including the automotive manufacturing industry, home manufacturing industry, electrical industry, household daily use, mobile phone industry, aviation and so on. It is an important and indispensable part of the manufacturing of various industries at present.
Common stamped parts
- Metal housings and shells
- Metal cups, cans and shells
- Light fittings and lamp parts
- Decorative stamped products
- Bearing assemblies
- Automotive components
- Various shapes
- Electrical controls and components
- Aerospace products and components
- Oil pipes
What is the metal stamping process?
The metal stamping process is a metal processing method based on the plastic deformation of metal, using a die and stamping equipment to apply pressure to the sheet to produce plastic deformation or separation of the sheet to obtain mechanical parts with a certain shape, size, performance and precision tolerances. The metal stamping process can be specifically divided into：
Progressive die stamping:This is one of the most common metal stamping processes. Manufactured using a single die, the strip is fed smoothly into the die press, where it is cut, punched or bent in different positions. The result is the creation of your customised part. This is one of the most economical types of stamping. More metal parts can be produced with greater precision in a shorter period of time.
Deep-drawn metal stamping:This is a relatively complex process dedicated to the production of deep drawing of various strip metals. Deep drawing involves drawing a metal slab into a die by means of a punch to shape it. When the depth of the drawn section exceeds its diameter, the process is known as deep drawn metal stamping
Multi-slide metal stamping:Multi-slide means that several slides are used to process the sheet metal. This process is relatively complex and is generally used to produce more complex metal parts, offering versatility for more complex parts, more flexibility for design changes, etc.
Features of metal stamping
|(1) Stamped parts have high dimensional accuracy and the same moulded parts are uniform in size. They can meet the general assembly and use requirements without further mechanical processing.|
|(2) Cold stamped parts are generally not subject to any cutting process or require only a small amount of cutting process.|
|(3) In the stamping process, the surface of the material is not damaged, so it has good surface quality and a smooth and beautiful appearance, which provides convenient conditions for surface painting, electroplating, phosphating, powder spraying and other surface treatment.|
|(4) Stamped parts are manufactured by stamping on the premise that the material is not consumed much. The parts are light in weight and have good stiffness, and after the plastic deformation of the sheet, the internal structure of the metal is improved, so that the strength of the stamped parts is increased.|
|(5) Compared with castings and forgings, stamped parts have the characteristics of thinness, uniformity, lightness and strength. Stamping can produce workpieces with reinforcing bars, ribs, undulations or flanges that are difficult to manufacture by other methods, in order to improve their rigidity.|
Hot stamping part types
- Stamping enterprises in the automotive manufacturing industry. Such as wheels, gears, etc. mainly based on deep drawing
- Stamping enterprises in the household industry. Such as aluminium windows, etc., mainly punching and shearing.
- Stamping enterprises in the electric appliance industry. Such as electric rice cookers, washing machines and other constituent parts.
- Household daily use stamping enterprises. Doing some handicrafts, such as tableware, etc. These factories have also seen great development in recent years.
- Stamping enterprises in the mobile phone industry. Such as, card slot, fixed frame, etc. These factories have emerged only after the development of household appliances in China, and most of them are distributed within household appliance enterprises.
- Special stamping enterprises. Such as the stamping of aviation parts, etc.
