Understanding Sheet Metal Fabrication Processes
Cutting
Cutting is one of the fundamental processes in sheet metal fabrication that involves separating metal sheets into desired shapes and sizes. Various methods like laser cutting, plasma cutting, and waterjet cutting are employed depending on material thickness and precision requirements. For instance, Protolabs utilizes advanced laser cutting techniques for high precision while SendCutSend allows users to upload CAD files for instant pricing.
Bending
Bending is the process of deforming sheet metal at specific angles to achieve desired shapes. This can be done using press brakes or other bending machines. It is crucial to understand the material’s properties to avoid cracking during the bending process. For example, Approved Sheet Metal emphasizes the importance of precision in their bending operations to ensure high-quality outputs.
Forming
Forming involves reshaping metal sheets into three-dimensional forms. Techniques such as deep drawing, roll forming, and stretch forming are common. Companies like Xometry provide custom forming services tailored to specific project needs, catering to a diverse range of industries.
Assembly
After individual components are fabricated, they often need to be assembled. This can involve welding, riveting, or using adhesives. Effective assembly techniques ensure the durability and functionality of the final product. West Coast Fab highlights their expertise in both fabrication and assembly to meet client specifications.
