ISO 9001 certified | ±0.1mm cutting tolerance | 1‑4 day lead time | No minimum order
What Is Sheet Metal Fabrication?
Sheet metal fabrication is the process of transforming flat metal sheets into finished parts through cutting, bending, welding, and finishing. It is widely used for enclosures, brackets, control panels, chassis, and structural components.
Sheet Metal Fabrication Services
Laser Cutting
High‑precision fiber laser cutting for clean edges and complex contours. Max thickness 6mm.

Sheet Metal Fabrication Finishing
Standard
No post‑processing. Parts are used directly after CNC cutting. Visible tool marks remain – ideal for functional prototypes and cost‑sensitive projects.
Anodizing
Electrochemical oxidation creates a durable, corrosion‑resistant layer on aluminum. Available in clear, black, or colors. Enhances wear resistance and appearance.
Hardcoat Anodizing
Thicker than standard anodizing (up to 50µm). Provides extreme wear and abrasion resistance for high‑friction or military/aerospace applications.
Conductive Anodizing
Modified anodizing process that leaves the surface electrically conductive. Ideal for EMI shielding, grounding contacts, and electronic housings.
Powder Coating
Electrostatic application of colored powder, then heat‑cured. Thick, impact‑resistant, and decorative. Excellent corrosion protection for outdoor parts.
Brushing
Mechanical abrasion produces fine, linear grain patterns. Common on stainless steel and aluminum for a satin, decorative finish that hides fingerprints.
Silkscreen
Durable ink printing for logos, labels, control panels, and instructions. High contrast, good adhesion, and chemical resistance.
Laser Marking
Permanent, high‑contrast marks (serial numbers, logos, 2D codes) without surface damage. No consumables, fast, and highly precise.

FAQs About Sheet Metal Manufacturing
What is the minimum order quantity for sheet metal parts?
No minimum – we accept one piece as well as large production runs.
What is the maximum sheet size you can handle?
Maximum part length is 800mm; sheet thickness up to 6mm.
What tolerances can you achieve?
Cutting: ±0.1mm, bending: ±0.3mm, general: ±0.2mm.
What file formats do you accept?
STEP, IGES, STL, SolidWorks, and PDF drawings.
What are the 2D file requirements for laser marking and silkscreen printing?
Requirements as follows:
- -Please upload the marking/silkscreen drawing based on the actual flat shape after bending (how the part looks once fully bent and flattened). Do NOT upload the unbent, unfolded sheet exported from CAD.
- -Clearly draw part outline and hole positions (if included).
- -Text (if included) must use a double-line font with a 0.2mm line width.
