Stamping utilizes a die to create various sheet-like parts, shells, and container-like workpieces from sheet metal on a press, a process known as cold stamping or simply stamping.

Metal stamping, also called pressing, is a cost-effective, high-speed manufacturing process capable of producing large quantities of identical metal parts. It's suitable for both short-term and long-term production, can be combined with other metal forming operations, and comprises specific processes such as punching, blanking, embossing, coining, bending, and flanging.

Compared to castings and forgings, stamping parts are thinner, more uniform, lighter, and stronger. Stamping can create workpieces with stiffeners, ribs, undulations, or flanges that enhance their rigidity. Precision molds ensure high accuracy and repeatability, with consistent specifications and the ability to create punched holes and bosses. Cold stamping parts typically require minimal or no additional cutting processing. While the precision and surface condition of hot stamping parts are slightly lower than cold stamping parts, they still surpass castings and forgings, requiring less cutting.

There are many situations in the stamping process of the mold, the most common stamping process. as follows:

1. Blanking: A general term for a stamping process that separates materials. It includes blanking, punching, grooving, sectioning, chisel cutting, edge trimming, tongue cutting, and cutting.

2. Making shape: A process that mainly involves cutting off excess material around the workpiece to meet size requirements.

3. Cutting tongue: Cutting a part of the material into a hole while leaving one side untouched, often used to set step distances.

4. Flaring: Expanding the end or a section of tubular parts outward into a trumpet shape, although less common.

5. Necking: Inward narrowing of a tubular part at the end or a section, opposite to flaring.

6. Punching: Separating material to create hollow parts using a punch and knife-edge.

7. Precision stamping: Used when the stamped part requires a full bright band.

8. Full Bright Blanking: Obtaining a full bright band in one-step punching, distinct from precision stamping.

9. Deep hole punching: Punching holes smaller than the material thickness, with the challenge of punch breakage.

10. Making convex hull: Punching a protrusion on flat material for further processing.

11. Forming shape: A general term for fluid material processes, including bending.

12. Bending: Obtaining desired angles and shapes through plastic deformation of flat material.

13. Beading: Punching convex pits in material to reduce rebound during sharp-angle bending.

14. Coining: Pressing special patterns on material surfaces, including embossing and pitting.

15. Rounding: Curling product shapes into circles.

16. Hole flanging: Inverting inner holes of stamping parts to obtain certain height side edges.

17. Leveling: Used when high product flatness is required to correct deviations caused by stress.

18. Shaping: Fine-tuning angles and shapes post-forming for stability.

19. Deep drawing: Obtaining hollow parts from flat materials through stretching.

20. Continuous deep-drawing: Multiple stretching processes through one or several dies in a material belt.

21. Thinning and deep drawing: Refers to thinning drawing series where wall thickness is less than material thickness.

22. Mandrelling: Making material convex, often used in complex-forming automotive parts.

The history of the stamping process.

The history of stamping dates back to 1890 when stamped bicycle parts were imported from Germany to the United States. American companies began manufacturing most bicycle parts using stamping machines developed by American machine tool manufacturers. Despite initial resistance from Henry Ford, several automakers adopted stamping before Ford Motor Company, as Ford eventually turned to stamped parts due to high demand and limitations in die forging capacity.

The advantages of the stamping process.

1. Compared to wire cutting, cold stamping offers several advantages, including high production efficiency, low processing costs, high material utilization rates, stable product dimensional accuracy, simple operation, and easy mechanization and automation. It is particularly suitable for mass production. As a crucial processing method in modern industry, stamping die forming is utilized to produce various sheet metal parts, offering lightweight, high rigidity, high strength, good interchangeability, and cost-effectiveness. The production process easily achieves mechanical automation and high efficiency, making it an advanced manufacturing technology with strong competitiveness across various industries, including automobiles, energy, machinery, information technology, aerospace, defense, and daily life applications.

2. With a foundation in mechanics, mathematics, material science, mechanical science and control, and computer technology, the basic theory of stamping discipline has been established. Stamping products, combined with modern advanced technology and mold centrality, lead the field.

3. Driven by significant market demand for products and supported by technological advancements, stamping technology plays an increasingly crucial role in national economic development, modernization, and the enhancement of living standards.

4. Modern stamping die production operates on a large scale, incorporating high-tech interventions to transition from manual operations to integrated manufacturing. Mechanization, automation, and intelligent integration characterize the evolving production process, exemplified by automatic stamping operations like those realized by Die Master WeChat: mujuren, which prioritize safety, efficiency, and material savings.

5. Many everyday items are manufactured using the stamping method, such as stainless steel rice bowls produced by pressing circular metal sheets with dies on press machines. Cold stamping, a metal pressure processing method, applies pressure to separate or deform various metal (or non-metal) sheets at room temperature, yielding parts of specific shapes.
