Sheet Metal Forming Process Advantages and Disadvantages

The manufacture of sheet metal cages involves many different sheet metal forming processes such as roll forming, stamping, peen forming and more. This list compares the good and bad of each process so that you can determine the right one for your own unique needs.

1. Roll Forming

This process is for long sections with constant complex transverse sections. These results in a good surface finish and have a high level of production. However, this process has high tool costs.

2. Stretch Forming

Stretch forming can be used to produce large parts with shallow contours but is only suitable for low quantity production. Cons are high labor costs, although the cost of equipment and equipment varies depending on the size of the part.

3. Drawing

The drawing process is for the production of shallow or deep parts with relatively simple shapes. Pro is a high level of production. Cons are the high cost of equipment and equipment.

4. Stamping

The clamping process actually includes a variety of operations, such as punching, blanking, embossing, bending, flanging, and coining. Images can be used to produce simple or complex shapes. This process has a high level of production and low labor costs and is suitable for large volume production. On the other hand, the cost of equipment can be very high. You can get different types of metal bending through

5. Rubber-pad Forming

The formation of a rubber pad is used for drawing and embossing simple or complex shapes. This process produces a sheet surface that is protected by a rubber membrane. High operating flexibility and low equipment costs are the main selling points.

6. Spinning

The spinning process is used to produce small or large axisymmetric parts. This process produces a good surface finish and has low tooling costs. However, labor costs can be high except automatic operations.

7. Superplastic Formation

The superplastic formation is used to produce complex shapes with fine detail and close tolerance. However, the disadvantages are long forming times; low production rates, and parts not suitable for high-temperature use.

8. Peen Formation

Peen formation is suitable for shallow contours on large sheets. This process is also used to straighten parts. The operation has high flexibility but the cost of equipment can be high.

9. Formation of Explosives

Explosive formation is used to produce very large sheets with relatively complex shapes but the shape is usually symmetrical axis. This process is suitable for low quantity production due to high labor costs and long cycle times. The main selling point is the low tooling costs.

10. Magnetic-pulse formation

The magnetic-pulse formation can be used for shallow, protrusion and embossing operations on relatively low strength sheets. This process is most suitable for tubular shapes. It has a high level of production, although it requires special tools.
