Stamping suppliers | | Stamping suppliers What is the stamping processé”›?/span>
Stamping is a forming and processing method that applies external force to sheets, strips, pipes, and profiles by means of presses and dies to cause plastic deformation or separation to obtain workpieces (stampings) of desired shape and size. Stamping and forging are both plastic processing (or pressure processing), collectively called forging. The stamped blanks are mainly hot-rolled and cold-rolled steel sheets and strips.
The cold stamping die process is a metal processing method, which is mainly aimed at metal materials, and the materials are forced to deform or separate through pressure equipment such as punches to obtain product parts that meet actual requirements, referred to as stamping parts.
The stamping process has high production efficiency, convenient operation, and easy realization of mechanization and automation. This is because stamping relies on punching dies and stamping equipment to complete the processing. The number of strokes of ordinary presses can reach dozens of times per minute, and the high-speed pressure can reach hundreds or even more than a thousand times per minute. May get a punch.
When stamping, because the mold guarantees the size and shape accuracy of the stamping parts and generally does not damage the surface quality of the stamping parts, and the life of the mold is generally longer, the quality of the stamping is stable, the interchangeability is good, and it has the characteristics of "identical".
Stamping can process parts with a larger size range and more complex shapes, such as stopwatches as small as clocks and clocks, as large as automobile longitudinal beams, covering parts, etc., plus the cold deformation and hardening effect of the material during stamping, the strength and rigidity of stamping are relatively high.
Stamping generally does not generate chips and scraps, consumes less material, and does not require other heating equipment, so it is a material-saving and energy-saving processing method, and the cost of stamping parts is lower.
Application of stamping process.
1. Due to the many advantages of stamping, the application of stamping is very extensive. It occupies a very important position in the production of automobiles, tractors, motors, electrical appliances, instrument toys, and daily necessities. Many parts manufactured by casting, forging, and cutting methods in the past are now replaced by stamping parts with good rigidity and lightweight.
2. According to statistics in recent years, in the production of electromechanical instruments and meters, 60% to 70% of the parts are completed by the stamping process. In automobile production, about 60% to 70% of the parts are made by the stamping process, and the labor amount of stamping production is 25% to 30% of the labor amount of the entire automobile industry. In electronic products, the proportion of stamping parts is also quite large. Metal products used in people's daily life, stamping parts account for a larger proportion, such as aluminum pots, stainless steel tableware, and so on. Therefore, stamping technology is widely used, and learning, researching, and developing stamping technology is of great significance to the development of my country's national economy and the acceleration of modern industrial construction.
3. There 60 to 70% of the world's steel products are sheets, most of which are stamped into finished products. The body, chassis, fuel tank, radiator sheet of the car, the steam drum of the boiler, the shell of the container, the iron core silicon steel sheet of the motor, and the electrical appliance are all stamped. There are also a large number of stamping parts in instruments, household appliances, bicycles, office machinery, living utensils, and other products.
4. Compared with castings and forgings, stamping parts are thin, uniform, light and strong. Stamping can produce workpieces with ribs, ribs, undulations, or flanging that are difficult to manufacture by other methods to improve their rigidity. Due to the use of precision molds, the accuracy of the workpiece can reach micron level, the repeatability is high and the specifications are consistent, and holes, bosses, etc. can be punched out.
5. Cold stampings are generally no longer machined or require only a small amount of machining. The accuracy and surface state of hot stamping parts are lower than those of cold stamping parts, but they are still better than castings and forgings, and the amount of machining is less.
6. Stamping is an efficient production method. The use of composite molds, especially multi-station progressive molds, can complete multiple stamping processes on one press, and realize the complete process from strip uncoiling, leveling, and punching to forming and finishing. Automatic production. With high production efficiency, good labor conditions, and low production cost, generally, hundreds of pieces can be produced per minute.
Packing and Shipping.
1. Each product is carefully packed with bubble bags and packed in cartons. In order to cause scratches due to knocks, which will affect the quality and use of the product, we will use wooden boxes specially designed for export for packaging and transportation.
2. All products will be transported according to customer needs, such as express, air shipping, sea shipping, and railway shipping.

---PDF, IGS, DWG, X_T, STEP(STP).
5. What surface treatment can you do?
---Including powder coating, sandblasting, painting, polishing, acid pickling, anodizing, enamel, zinc plating, hot-dip galvanizing, and chrome plating.
6. What is your way of packing?
---Each product is carefully packed with bubble bags and packed in cartons. In order to cause scratches due to knocks, which will affect the quality and use of the product, we will use wooden boxes specially designed for export for packaging and transportation.
