Metal bending shapes the metal sheet by applying force to achieve desired angles and curves. This process is crucial for creating components that require specific geometric features and ensures that parts fit together correctly in the final assembly.

Common materials include steel, aluminum, stainless steel, and copper. The choice of material depends on the required strength, corrosion resistance, weight, and cost considerations for the application.

Surface finishing options include powder coating, anodizing, plating, and painting. These finishes improve the metal's appearance, durability, and resistance to environmental factors like corrosion and wear.

Warping or distortion can be minimized by using proper tooling, controlling the bending parameters, and selecting the appropriate material thickness. Pre-bending techniques and adjusting the die or punch can also help manage these issues.

The cost is influenced by factors such as material type, processing complexity, and production volume. Efficient processing techniques, such as laser cutting for precision and stamping for high volumes, can help optimize costs. Additionally, choosing cost-effective materials and finishes can further impact the overall product cost.
