Sheet Metal Fabrication
Sheet metal fabrication transforms flat metal sheets into functional parts and assemblies through cutting, bending, forming, and joining operations. Raw sheet material is cut to shape by laser or CNC punching, formed to geometry using a CNC press brake, then joined and finished to specification.
The process is suitable for enclosures, brackets, panels, frames, and structural components across a wide range of industries. Sheet metal parts can be produced in prototype quantities with short lead times and scaled to production volumes without retooling.
What Sets Us Apart
Engineering-Led Manufacturing
In-house laser cutting and bending
fiber laser cutting and CNC press brake forming operated at our Shenzhen facility. No supplier coordination required.
Tolerances to ±0.1mm
laser cutting and forming for structural and cosmetic sheet metal parts across steel, stainless, and aluminium.
Fast turnaround
prototype sheet metal parts from 3-5 business days. Production batches from 1-2 weeks.
ISO 9001:2015 certified
dimensional inspection and surface quality verification on every batch.
Our Sheet Metal Capabilities
Laser Cutting
Fiber laser cutting for steel, stainless steel, and aluminium sheet up to 6mm thick. Produces flat blanks with clean cut edges to ±0.1mm positional tolerance. Suitable for complex profiles, slots, holes, and contour shapes directly from DXF or STEP files.
CNC Press Brake Bending
CNC press brake forming produces accurate bends, flanges, and formed profiles from laser-cut blanks. Bend angles held to ±0.5 degrees. Suitable for enclosures, brackets, and structural frames requiring multiple bends and consistent repeatability.
Welding
TIG, MIG, and spot welding available for joining sheet metal components and assemblies. TIG welding produces clean cosmetic welds on stainless steel and aluminium. MIG welding for structural steel assemblies. Spot welding for high-speed joining of thin gauge panels.
Hardware Insertion
PEM nuts, threaded standoffs, studs, and clinch fasteners pressed into sheet metal parts using automated insertion equipment. Provides strong, reliable threaded interfaces without secondary machining. Suitable for electronic enclosures, panels, and mounting assemblies.
Surface Treatment
Powder coating, zinc plating, anodising, brushing, and polishing available as standard. Colour matching to RAL or Pantone reference available for powder coat. Surface treatment applied in-house or through verified local partners with full quality documentation.
Our Process
STEP 1
DFM Review
Engineers check your design for bend radii, minimum hole sizes, flange lengths, material grain direction, and forming sequence.
STEP 2
Material and Finish Confirmation
Sheet material grade and surface treatment confirmed against load, environment, and aesthetic requirements.
STEP 3
Laser Cutting
Flat blanks cut from sheet material to profile using fiber laser. Holes, slots, and cutouts produced in the same operation.
STEP 4
CNC Bending
Blanks formed to geometry using CNC press brake. Bend sequence planned to avoid tool collision and maintain dimensional accuracy.
STEP 5
Joining and Hardware
Welding, riveting, or hardware insertion completed as specified. Assemblies jigged for positional accuracy.
STEP 6
Surface Treatment and Dispatch
Powder coat, plating, or anodising applied. Parts inspected dimensionally and for surface quality, then packed and shipped.
Materials
NICE Rapid works with a broad range of sheet metal materials. Selection depends on strength requirements, corrosion environment, weight targets, and surface finish.
| Material | Key Properties | Suitable Applications |
|---|---|---|
| Cold-Rolled Steel (SPCC) | Good formability, cost-effective, readily paintable | Enclosures, brackets, panels, structural frames |
| Stainless Steel 304 | Corrosion resistant, good weld quality, hygienic surface | Food equipment, medical housings, marine components |
| Stainless Steel 316 | Enhanced corrosion resistance over 304, higher nickel content | Medical devices, chemical processing, coastal environments |
