Sheet metal design plays a crucial role in the success of the fabrication process. Here are some tips to help you design better sheet metal products:

1. Simplify the design: Keep the design simple and avoid complex shapes and details that are difficult to fabricate. Simple designs are easier to produce, faster to manufacture, and often result in a more cost-effective product.

2. Consider tolerance: Sheet metal has a certain level of tolerance, meaning that the actual thickness of the metal may vary slightly from the specified thickness. When designing, consider the tolerance range of the sheet metal being used and design accordingly.

3. Use bends instead of cuts: Bends are typically stronger than cuts, so try to use bends instead of cuts whenever possible to create the desired shape.

4. Minimize the number of cuts: The more cuts a sheet metal product requires, the more complex and time-consuming the fabrication process will be. Minimize the number of cuts by using folds, bends, and other forming techniques to create the desired shape.

5. Avoid sharp corners: Sharp corners can weaken the metal and make it more susceptible to cracking. Consider using rounded corners or adding a radius to sharp corners to increase the strength of the product.

6. Consider material utilization: Consider the material utilization when designing the product. The goal is to minimize waste while still achieving the desired shape and size.

7. Test the design: Before starting the fabrication process, test the design to make sure it's feasible and will result in a product that meets your specifications. This can be done using computer-aided design (CAD) software or by building a prototype.

By following these design tips, you can ensure that your sheet metal products are well-designed, easier to manufacture, and cost-effective to produce.
