- Final Inspection
- Dcumentation Management
Automation Level Reflects Factory Stability
The meatured metal processing provider introduces automation production equipment, such as robotic loading systems, automated stamping lines, MES systems and barcode traceability. Factories still relying heavily on manual operation are often considered higher-risk suppliers for long-term OEM projects.
Supply Chain Integration Is a Major Advantage
The integrated processes can provide in house processing for the metal stamped part. The tough stamped part is formed, it requires deburring, cnc machining, welding, surface finishing, assembly and packing. As a CNC machining company in China, you can position your service as: “One-stop manufacturing solution integrating CNC machining, sheet metal stamping, surface finishing, and assembly support.”
“A reliable sheet metal stamping manufacturer should not only provide competitive pricing, but also possess strong engineering capability, certified quality systems, in-house tooling support, and stable mass-production management. For OEM projects, especially in automotive, electronics, and industrial equipment industries, suppliers with ISO/IATF certifications, PPAP experience, automated production, and integrated CNC machining capability are the preferred long-term manufacturing partners.”

Modern Stamping Technologies
Progressive Stamping Process: Focus on small size electrical metal stemped parts used for automotive industry, such as battery contacts, sensor housings, terminal connectors.
Transform Stamping Process: It is large one, A finished stamped part passes a few stamping steps, The metal sheet requires transportion fingers or robotic hands to move on stations to stations, it is time-consuming process, but tolorance is tight, range from 0.01mm-0.03mm. Such as engine mounting brackets, structural chassis components, reinforcement panels.
- Deep Drawing Process: Some water-proof containers, housings in which electric-magnic signal is shieded completely, using thin metal sheet to deep draw, and form precision stamped parts. Ensure its integrated steady structure and accuracy dimensions.

| General metal stamping | ±0.10 mm to ±0.30 mm |
| Precision metal stamping | ±0.02 mm to ±0.05 mm |
| Fine blanking | ±0.01 mm to ±0.03 mm |
| Micro stamping | ±0.005 mm to ±0.02 mm |
| Hole diameter tolerance | ±0.01 mm to ±0.05 mm |
| Bending angle tolerance | ±0.5° to ±1° |
| Flatness tolerance | Depends on thickness and material |
| Progressive die repeatability | Very high consistency in mass production |
What is the difference between progressive die and transfer stamping?
Progressive die stamping and transfer stamping are two important metal stamping manufacturing processes used for high-volume production, but they differ greatly in tooling structure, part movement, complexity capability, and production applications.
In progressive die stamping, a metal strip continuously feeds through multiple stations inside one die set. Each station performs one operation step until the final part is completed. While In transfer stamping, the workpiece is seperated from the strip early in the process. Mechanical transfer fingers or robotic systems move the individual part from station to station.
