Sheet metal fabrication is the process of cutting, bending, and assembling flat metal sheets into functional parts such as chassis, enclosures, and brackets. At JS Model in Shenzhen, fabrication typically combines fiber laser cutting, CNC press-brake bending, welding or PEM hardware insertion, and finishes like powder coating or anodizing for prototypes and small-batch runs.
Laser cutting, bending, welding & finishing
Fiber laser cutting, CNC press-brake bending, welding/hardware, and finishing in one Shenzhen shop — standard tolerance ±0.2 mm, laser hole placement to ±0.1 mm.
-
Laser Cutting
Fiber laser cutting for flat patterns and complex profiles with hole placement to ±0.1 mm — ideal for chassis panels and enclosure blanks.
-
CNC Bending
CNC press-brake forming for accurate flanges, channels, and box bends on aluminum, stainless, and steel sheet.
-
Welding & Assembly
TIG/MIG welding plus PEM nuts, studs, and standoffs so brackets and enclosures ship as ready-to-assemble kits.
-
Surface Finishing
Powder coating, anodizing, and silkscreen marking to protect parts and match cosmetic requirements.
Sheet metal materials in stock
Aluminum 5052, stainless 304/316, cold-rolled steel, and galvanized sheet stocked for rapid prototype and short-run fabrication.
Sheet metal surface finishes
Protect and brand fabricated parts with anodizing, powder coating, and silkscreen — matched to cosmetic and outdoor durability needs.
-
Anodizing
Type II & III anodizing increases corrosion resistance and adds color options on aluminum sheet parts.
-
Powder Coating
Durable powder coat in matte, gloss, and texture finishes for steel and aluminum chassis.
-
Silkscreen
High-contrast silkscreen legends and branding printed directly onto fabricated metal surfaces.

Common questions
Sheet metal fabrication FAQ
JS Model's standard sheet metal tolerance is ±0.2 mm for general dimensions and ±0.1 mm for laser-cut hole placements. Tighter tolerances are available after engineering review of material thickness, bend sequence, and critical features.
Send 2D/3D drawings (STEP, IGES, or PDF), material preference, quantity, tolerance notes, and surface-finish requirements. Include PEM/hardware or assembly needs so JS Model can quote a complete kit rather than cut-only blanks.
Yes. JS Model stocks common metric and imperial self-clinching fasteners — including nuts, studs, and standoffs — and can install them during sheet metal fabrication so enclosures arrive assembly-ready.
JS Model prefers to supply sheet stock to ensure machine compatibility and material certificates, but customer-supplied specialized alloys can be reviewed case by case for fit with laser cutting and press-brake tooling.
