Sheet Metal Fabrication Services
JADE-CNC provides sheet metal fabrication services for custom enclosures, brackets, panels, covers, housings, prototypes, and low-volume metal parts. Projects can include laser cutting, punching, bending, welding, deburring, surface finishing, inspection, and assembly support based on customer drawings.
Custom Sheet Metal Fabrication Service
Sheet metal fabrication is suitable for parts made from flat metal sheet that need cutting, bending, forming, welding, finishing, or assembly. JADE-CNC reviews each drawing according to material grade, sheet thickness, bend direction, hole position, weld area, surface finish, tolerance requirement, and production quantity before confirming the fabrication route.
Sheet Metal Fabrication Process
Laser Cutting
Using a focused laser beam to melt, burn, or vaporize material, achieving high-precision cuts with excellent edge quality.
Welding
Join materials, typically metals, by causing coalescence through heat, pressure, or both, resulting in a permanent bond.
Bending
Machine force is applied to sheet metal, causing it to plastic ally deform and achieve a desired angle or shape along a straight axis.
Stamping
Using a press and specialized dies to cut or form sheet metal into specific, often complex, two-dimensional or three-dimensional shapes.
What JADE-CNC Reviews Before Sheet Metal Fabrication
Sheet metal parts can look simple on a drawing, but manufacturability depends on material thickness, bend radius, hole position, flat pattern design, welding distortion, surface finish, and inspection requirements. JADE-CNC reviews these details before quotation so the fabrication plan can match the actual part function.
Material and Thickness
JADE-CNC reviews material grade, sheet thickness, flatness, corrosion resistance, conductivity, weight, and finish compatibility before fabrication.
Bend Radius and Forming Direction
Bend radius, flange length, forming direction, and bend-to-hole distance are checked to reduce cracking, deformation, and fit issues.
Hole, Slot, and Feature Position
Hole sizes, slots, countersinks, threaded inserts, and cutout positions are reviewed against cutting, punching, bending, and assembly requirements.
Welding and Assembly Areas
Weld locations, seams, tabs, fasteners, PEM inserts, and assembly interfaces are reviewed to control distortion and improve fit.
Finish and Inspection Requirements
Powder coating, anodizing, plating, brushing, passivation, masking, cosmetic surfaces, and inspection requirements are reviewed before production.
Key Factors When Choosing Sheet Metal Materials
Sheet metal material selection should be based on part function, thickness, bending behavior, corrosion exposure, surface finish, welding requirement, appearance, and cost target. For enclosures, brackets, panels, covers, and formed components, material choice also affects bend radius, flatness, hole accuracy, coating quality, and assembly fit.
- Material Model: Wide range of materials (e.g., mild steel, stainless steel, aluminum) with varying properties for different applications.
- Cutting:Utilizing methods like laser cutting, punching, and shearing for precise and efficient blanking.
- Forming Processes: Shaping metal through bending, stamping, and deep drawing using presses and dies.
- Joining Techniques: Assembling parts primarily via welding, riveting, and fastening.
- Surface Finishing: Applying treatments such as powder coating, plating, or anodizing for protection and aesthetics.

Sheet Metal Fabrication FAQ
Please provide a 3D CAD file and 2D drawing with material grade, sheet thickness, bend notes, hole positions, tolerances, surface finish, quantity, and assembly or packaging requirements.
Common materials include aluminum, stainless steel, cold rolled steel, galvanized steel, copper alloys, and other sheet metals depending on strength, corrosion resistance, conductivity, weight, surface finish, and forming requirements.
Sheet thickness affects cutting method, bend radius, flange length, hole position, welding distortion, stiffness, weight, and final tolerance. Thickness should be confirmed before quotation.
Yes. JADE-CNC can review prototype and low-volume sheet metal fabrication projects for enclosures, brackets, panels, covers, housings, fixtures, and formed components based on customer drawings.
A sheet metal project may include laser cutting, punching, bending, forming, welding, riveting, PEM inserts, deburring, surface finishing, inspection, assembly support, and packaging.
Bend radius should match the material, sheet thickness, forming direction, flange length, and function of the part. Critical bends should be clearly marked on the drawing.
Yes. Powder coating, anodizing, plating, brushing, polishing, passivation, painting, and other finishes can be reviewed according to material, appearance, corrosion exposure, masking areas, and inspection requirements.
Yes. Welding, rivets, threaded inserts, fasteners, tabs, brackets, and light assembly requirements can be reviewed before production. Weld locations and assembly interfaces should be shown on the drawing.
Sheet metal tolerances depend on material, thickness, cut features, bend features, welding, finish, and part size. Flat cut features and formed parts should be reviewed separately because bending and welding can introduce variation.
Inspection may include dimensional checks, hole and slot position, bend angle, flatness, thread or insert fit, surface finish, coating appearance, quantity, labeling, packaging, and customer-required documentation.
