Metal Stamping

Stamping (also known as forming or pressing) is a manufacturing process used to convert flat metal sheets into final shapes. With 12 stamping machines rated from 25 tons to 630 tons, Shanghai Yixing Technology can meet customers all demand from simple to complicated stamping parts.

What is Custom Metal Stamping?

Stamping, a method that uses a press and die to exert external forces on materials like plates, strips, pipes, and profiles, results in plastic deformation or separation. This process aims to achieve the desired shape and size of the workpieces, known as stamped parts. Both stamping and forging are categorized under plastic or pressure processing, often collectively referred to as forging. The primary materials for stamping are hot-rolled and cold-rolled steel plates and strips. Notably, 60% to 70% of the global steel production is in the form of sheet metal, with a significant portion being processed into final products through stamping.


Metal Stamping Material

Metal stamping uses various metals and alloys to produce high-performance parts with extraordinary precision and repeatability. When selecting metal materials for stamping parts, it is important to consider their compatibility with the metal stamping process and your application.

Factors such as tensile strength, hardness, ductility, and machinability will affect the ability of metals to accurately form and form without fracture or loss of strength.

Below is the short summary of the stamping material you can choose from:

Carbon steelS235, S345, SPCC, SPEC, CRS, HRS, DC01, SAPH440 etc
Aluminum alloysAL5052, AL5754,AL6061, AL6063, AL1060 etc

FAQ of Metal Stamping

FAQ of Metal Stamping

  • What is the difference between metal stamping and deep drawing?

    Below are some short difference comparisons:

    1. Accuracy

    The accuracy of deep drawn parts is measured by the thickness of the material and the radius of the inner corner. Deep drawing usually produces parts with higher precision than stamping. Only by using single point drawing can high dimensional accuracy be achieved. The surface finish of stamped parts is always rougher and has lower dimensional accuracy than that of drawn parts.

    2. Surface treatment

    Deep drawn parts typically have a smoother surface finish than stamped parts, as there is only one deformation process during positional manufacturing. Stamping requires two processes (forming and indentation) to produce parts, resulting in a more complex and rougher surface finish. Embossing techniques can be added to enhance the appearance of formed metal panels. However, it has not improved its structural characteristics as it only increases material thickness without changing shape or size. The embossing process does not provide structural support for the parts.

    3. Material thickness

    On average, due to the metal flow during the forming process, the cross-section of deep drawn parts is thinner than that of stamped parts. The material is redistributed throughout the entire process, eliminating material accumulation on the mold wall and achieving uniform distribution. This redistribution also enhances the flow of metal particles throughout the entire part, thereby enhancing mechanical performance. When designing consistent strength, deep drawing can provide better results as it can redistribute materials. Although stamping can also produce parts with uniform thickness, its reliability is not high and it is difficult to achieve uniform thickness.

    4. Appearance

    One of the drawbacks of deep drawing is that it can sometimes cause surface deformation, such as wrinkles, stretching, and tearing. Although these deformations are not always visible, they may lead to less satisfactory appearances. Stamping can produce a smooth surface without deformation. From a purely aesthetic perspective, this makes stamped parts more popular.

  • What are the types of stamping?

    Stamping can be divided into four categories:

    1. Progressive Die Stamping

    Progressive die stamping is a manufacturing method that automatically pushes the metal strip on the coil through a series of forming dies. Each forming die simultaneously operates on the blank, making the part closer to its final shape. When the metal strip reaches the final station, the finished product will separate from the metal strip.

    2. Compound Die Stamping

    Unlike transfer or progressive die stamping, compound molds can complete multiple cuts, stamping, and bending in one stroke, making them cost-effective in medium batch production. The speed varies with the size of the parts. It excels at rapidly producing simple parts with high repeatability, but may not be suitable for complex designs where progressive stamping is more desirable. Convex and concave molds are easily limited by the minimum wall thickness and are not suitable for certain parts with small inter hole spacing and inter hole and edge spacing.

    3. Transfer Die Stamping

    Transfer die stamping treats each part as a separate unit. It first separates the parts from the metal strip and then moves them to various workstations for specific operations. For complex parts with features such as knurling, ribs, and threads, this method is very suitable. It excels in manufacturing sleeve applications and deep drawing components. For small-scale production operations, this is also a very effective and economical choice as it is the preferred choice for producing large parts.

    4. Fourslide Stamping

    Unlike vertical stamping, four slider stamping uses four horizontally moving sliders, which are driven by a coupling shaft and gears. These sliders perform orthogonal impacts on the workpiece to ensure the accuracy and consistency of metal forming. This technology is used in various industries in the automotive, electronics, and aerospace sectors to manufacture complex and precise components.

  • Is stamping cheaper than casting?

    From the perspective of manufacturing technology, sheet metal stamping is simpler than cast iron production process, and the required equipment and labor costs are relatively low, so the production cost of sheet metal is relatively low.

    The production process of cast iron is relatively complex, requiring high-temperature resistant equipment and complex production processes, resulting in relatively high production costs.

    Metal stamping is only for sheet metal. It is a cold-press method. Its characteristics are thin thickness, high strength, and diverse shapes, widely used in fields such as machinery, electronics, communication, and construction.

    Cast iron is a casting material made by pouring molten iron or melted scrap iron and other iron alloys into a mold for cooling. Its characteristics include good stability, high compressive strength, wear resistance, and strong corrosion resistance. Widely used in automobiles, machinery, construction, pipelines, and other fields.

    Sheet metal stamping and cast iron are different in terms of materials, manufacturing processes, and applicability. From the perspective of production cost, the production cost of sheet metal is relatively low, while the production cost of cast iron is relatively high. Therefore, in different situations, the prices of sheet metal and cast iron also differ significantly.

    Overall, the pricing of sheet metal and cast iron should be considered based on different situations, and it cannot be simply said which is more expensive. In terms of material selection and manufacturing, a choice should be made between the two based on specific circumstances to achieve optimal cost-effectiveness.
