Design Considerations for Sheet Metal Forming
Understanding Material Deformation
Understanding how materials deform when subjected to different forces is essential for sheet metal forming.
- Elastic Deformation： Temporary change in form occurs when the material returns to its original shape after removing the force.
- Plastic Deformation： Permanent plastic deformation happens when the material stretches past its yield point.
By recognizing these behaviors, we can predict how metals behave during the forming processes and ensure the integrity of the final product.
The three most important design parameters are thickness, bend radius, and edge conditioning.
When designing sheet metal forming, there are several important parameters to consider:
- Dikte： Metal thickness has an impact on its strength and bendability. Thicker metals tend to be more robust but also less flexible.
- Bend radius: The bend radius is the minimum radius at which you can bend metal sheets before weakening. A smaller bend radius may lead to metal fatigue and cracking.
- Edge conditioning: The edge of the metal sheet is essential, particularly in applications with high stress. Edge rolling and ontbramen are two standard methods to improve durability and safety.
We at Shengen consider all of these factors and leverage our expertise to optimize each design for functionality and manufacturability.

Cold Forming vs. Hot Forming
The temperature of the metal during formation plays an essential role in the outcome and process.
- Cold Forging: The process is performed at or near room temperature to maintain the strength and hardness of the metal. This method is ideal for achieving smooth surfaces and precise details. It may be more complex and require more significant force, which can make the material harder.
- Forming Hot: Forming hot involves heating metals above their recrystallization temperatures. The metal becomes more pliable and easier to work with. This trade-off can include changes to the microstructure of the metal and a reduction in strength.
The role of temperature in metal forming
The temperature has a significant impact on the behavior of metals during forming.
- Material properties: Heating and cooling metals alter their properties, such as hardness, strength, and flexibility. This affects how they react to deformation.
- Forming forces: Hotter metals need less force to form, which reduces wear on machines and tools.
- Surface finish and tolerance: Temperature affects the final product’s surface finish and dimensional tolerance. Cold forming produces smoother surfaces with tighter tolerances.
Understanding these dynamics will help you select the best forming process to meet your needs and ensure the highest performance and quality of the product. We at Shengen carefully consider the impact of temperature on every project to provide optimal results for our customers.
