Overview

What is Sheet Metal Fabrication?

Sheet metal fabrication is a comprehensive manufacturing process that transforms flat metal sheets into functional parts and assemblies through cutting, bending, forming, and joining operations. The process combines multiple techniques to create everything from simple brackets to complex enclosures, chassis, and structural components.
The process involves six key stages: Design & Engineering (CAD analysis, flat pattern development, nesting optimization), Cutting Operations (laser, plasma, waterjet, CNC punching), Bending & Forming (press brake, roll forming, stamping), Joining & Assembly (TIG/MIG/spot welding, riveting), Finishing (deburring, polishing, powder coating, anodizing), and Quality Control & Delivery.
Sheet metal fabrication at Partwork offers end-to-end manufacturing - from raw sheet to finished assembly - with professional-grade equipment and skilled craftsmen. We handle everything from prototypes to production runs of 10,000+ units.

Design Guidelines for Sheet Metal

Optimize your design for manufacturability and cost-effectiveness

Minimum bend radius: 1x material thickness (recommended 1.5-2x)
Minimum flange length: 3x material thickness + bend radius
Minimum hole diameter: 1x material thickness
Hole to edge distance: Minimum 2x material thickness
Hole to bend distance: Minimum 2.5x material thickness + bend radius
Corner relief required where two bends meet at 90°
Laser cutting tolerance: ±0.1mm
Bending tolerance: ±0.5mm, ±0.5° angular
Weld shrinkage: Account for 0.5-1mm distortion on long welds
Standard hole sizes (Ø6, Ø8, Ø10mm) preferred for punching
