Frequently Asked Questions (FAQs)

Frequently Asked Questions About Sheet Metal Design in Chinese Factories

What are the key processes involved in sheet metal fabrication?

Sheet metal fabrication involves two main processes: cutting and forming. Cutting removes excess metal to achieve the desired shape, while forming includes techniques like bending, stamping, and punching to shape the metal into the required form. These processes work together to create the final product.

How do I select the right material for my sheet metal project?

When selecting a material, consider its manufacturability and the specific requirements of your project. For example, aluminum is easier to cut than steel, but steel is stronger and more durable. Choose a material that balances your needs for strength, cost, and ease of manufacturing.

What are some common mistakes to avoid in sheet metal design?

One common mistake is not including bends in your CAD file, which can lead to the need for multiple parts and additional labor. Another mistake is placing features like holes or tabs too close to bends, which can cause deformation. Use the 4T rule to keep features at least 4 times the material thickness away from bend lines.

What are the guidelines for bending in sheet metal design?

For bending, ensure the folded height is at least twice the material thickness plus the bending radius. The bending radius should be reasonable to avoid excessive springback or material breakage. Too small a radius can cause folding or breakage, especially in hard materials like aluminum alloys.

How can I ensure precision and efficiency in my sheet metal design?

To ensure precision and efficiency, follow strict design for manufacturing (DFM) practices. Provide comprehensive details in your CAD files, including hardware specifications. Avoid overly complex bending structures, as they can increase costs and labor. Instead, consider split structures that can be combined through welding or riveting. Communicate with the manufacturer during the design and trial production phases to ensure your design meets production requirements.
