What Is Sheet Metal? How Is Sheet Metal Processed?

Sheet metal refers to the processing of thin sheet metal (usually no more than 6mm) into various shapes of metal products, encompassing flat, bent, stamped, and formed forms. Sheet Metal Stamping Parts products are widely used in various industries and fields, including automotive manufacturing, construction, electronics manufacturing, aerospace, and medical equipment, due to their advantages such as light weight, high strength, corrosion resistance, smooth surface, and low manufacturing cost. Common sheet metal materials include cold-rolled steel sheets, galvanized sheets, aluminum sheets, and stainless steel sheets.

Material Preparation: Select suitable Stamped Sheet Metal materials and cut them to the required dimensions and shapes according to design requirements.

Pre-processing Treatment: Degreasing, cleaning, and polishing the material surface to create favorable conditions for subsequent processing.

CNC Punching: Using a CNC punch press, the Custom Metal Stampings material is cut, punched, grooved, and embossed according to the design drawings.

Bending: According to design requirements, the flat parts processed by the punch press are bent to form the required three-dimensional shape.

Welding: If necessary, weld the bent Stamping Parts.

Surface Treatment: Apply surface treatments such as painting, electroplating, and polishing to the finished product to improve its appearance and performance.

Assembly: Assemble the various components to form a complete finished Deep Drawn Metal Stamping product.

Sheet metal processing typically requires the use of various mechanical equipment and tools, such as CNC punch presses, bending machines, welding equipment, and grinding machines. Safety operating procedures must be followed during processing to ensure efficiency and Precision Metal Stamping product quality.

The calculation of Progressive Die Stamping bending dimensions needs to comprehensively consider factors such as the sheet metal thickness, bending angle, and bending length. It can generally be performed in the following steps:

Calculate the length of the Stamped Sheet Metal, i.e., the length of the bending line, which is equal to the sum of the lengths of the bending section and the straight segment.

Calculate the length after bending, considering the length occupied by the bending angle, which can be calculated based on the bending angle and the sheet metal thickness.

Calculate the unfolded length of the Custom Metal Stampings, i.e., the length of the sheet metal when fully unfolded, calculated based on the length of the bending line and the bending angle.

Calculate the width after bending, which is the sum of the widths of the two parts of the "L"-shaped part formed after the sheet metal is bent.

It is important to note that different sheet metal materials, thicknesses, and bending angles will all affect the dimensional calculation results.

Therefore, in actual calculations, it is necessary to perform accurate calculations based on the specific sheet metal material and processing requirements. For complex bent Stamping Parts, CAD software can be used for simulation and calculation to obtain more accurate dimensional data.
