Many sheet metal forming methods are used in the manufacture of sheet metal enclosures. The following list compares each process to help you choose the best one that suits your unique needs.
1. 1.Roll Forming
This method is used for parts that are long and have complex cross-sections. This process produces a high level of surface finish as well as high production rates. This process comes with high tool cost.
2. Stretch Forming
While stretch-forming can produce large parts with shallow contours, it is not recommended for high quantities. However, the cons include high labor costs. The tooling and equipment prices vary depending upon part size.
3. 2.
This drawing process allows for the production of small or large parts, with very simple shapes. High production rates are one of its greatest strengths. Its high cost of tooling and equipment are the cons.
4. Stamping
The stamping process includes many operations such as blanking and embossing. The ability to draw can allow you to create complex or simple shapes. The process is highly efficient and can be used to produce large quantities of products. However, the tooling and equipment cost can be quite high.
5. Forming rubber pads
The rubber-pad method is used to draw and emboss simple or complicated shapes. The result is a sheet with a protected surface made of rubber membranes. Its main strengths are flexibility and low cost of tooling.
6. 6.
You can use the spinning process to create small and large axisymmetrical pieces. It produces high-quality surface finishes and low tooling expenses. But, labor costs are high when operations cannot be automated.
7. 7.
For complex shapes, superplastic forming can be used. It allows for fine detail and precise tolerances. But, there are some drawbacks: the forming times can be long and production rates low. Also, parts may not be suitable for high temperature use.
8. The Peen Formation
For small contours, peening is ideal for large sheets. The process can be used also to straighten pieces. Although it is very flexible in operation, the equipment cost can sometimes be prohibitive.
9. Explosive Forging
The process of explosive forming can be used to create large, complex sheets. However, the shapes are usually axisymmetric. Due to its long cycle time and high labor costs, this method is ideal for production in low quantities. This process is known for its low costs of tooling.
10. 10.
You can use magnetic-pulse for small forming operations, such as bulging or embossing on sheets with low strength. This method is ideal for making tubular forms. Although it has high production speeds, this process requires special tooling.
