Industry Overview
Sheet metal fabrication is a manufacturing technology that processes metal sheets (typically 0.5mm‑20mm thick) through cutting, punching, bending, welding, and surface finishing to form desired shapes. Its core characteristics are fast forming, light weight, and relatively low cost. Typical products include cabinets, enclosures, frames, and protective covers. Sheet metal fabrication complements CNC machining – the former excels at structural forming and protection, while the latter specializes in precision cutting and complex features.
Customer Needs
|
Requirement |
Description |
|
Precision & Tolerance Control |
Bending angle consistency, hole position accuracy, and welding distortion control are top priorities. Process compensation ensures interchangeability. |
|
Welding Quality & Strength |
Weld appearance, penetration, and leak‑tightness directly affect product reliability. Certified welders and WPS are advantageous. |
|
Surface Finish Quality |
Appearance parts demand high surface quality – coating adhesion, color consistency, and no runs/sags. |
|
Lead Time Reliability |
Sheet metal parts are often on the critical path. Delivery delays heavily impact customers; on‑time delivery rate is key. |
|
Cost & Pricing |
High‑volume orders are cost‑sensitive. Customers compare material utilization and nesting optimization. |
