Helps reduce fitment issues and minimize costly revisions during manufacturing.
DFM Recommendations
Recommendations covering bend design, hole placement, material selection, and manufacturing efficiency.
Supports improved manufacturability and production consistency.
Assembly Review
Evaluation of multi-part assemblies involving sheet metal, machined components, hardware, and welding operations.
Helps improve assembly compatibility and reduce rework.
Precision Sheet Metal Fabrication Technical Overview
| Capability | Typical Reference | Notes |
|---|---|---|
| Material Thickness | 0.5–6 mm sheet metal, subject to material and process review | Forming feasibility depends on material, thickness, bend length, geometry, and available tooling. |
| Cutting Tolerance | Typically ±0.10–0.25 mm for laser-cut sheet features | Actual tolerance depends on material, thickness, geometry, feature size, and cut-edge requirements. |
| Welding Processes | TIG / MIG / spot welding | The welding method is selected based on material, thickness, joint design, strength needs, appearance requirements, and distortion control. |
| Surface Finishing | Powder coating, anodizing, zinc plating, electroless nickel plating, and passivation | Finishing options depend on base material, cosmetic requirements, corrosion-resistance needs, dimensional requirements, and processing sequence. |
*Values are typical reference ranges for project discussion and should not be treated as guaranteed limits. Tighter requirements, welded assemblies, and formed features across bends should be reviewed before production.
