Sheet Metal Fabrication Capabilities
Explore fabrication processes for custom metal components, from flat sheet cutting to formed parts and assembled structures.
Laser Cutting
Laser cutting uses a focused laser beam to cut sheet metal into specified profiles, openings, and contours. It is suitable for brackets, panels, flat components, and parts with complex two-dimensional geometries.
Forming & Bending
Sheet metal forming transforms flat blanks into functional three-dimensional shapes. Bending can create flanges, channels, brackets, mounting features, and enclosure structures according to the part design.
Deburring & Edge Finishing
Deburring removes burrs and sharp edges left by cutting or punching. Edge finishing can improve handling safety and help prepare components for assembly or subsequent surface treatments.
Welding & Assembly
Multiple sheet metal components can be joined through suitable welding, riveting, or fastening methods to create enclosures, frames, brackets, and custom assemblies.
How Does Sheet Metal Fabrication Work?
During the sheet metal fabrication process, thin sheet metal stock is placed on a flat bed where a laser cutter
(1) draws programmed part patterns. Depending on the part geometry, a sheet metal punch
(2) can form additional features. Once the parts are deburred, they move to the press brake
(3) where they are formed into the final geometries. Additional secondary operations are often used to finish the sheet metal parts.
