How to Audit a PPGI Factory for Stable Bulk Production
PPGI.LTD shows how to audit a PPGI factory by following one order from the approved requirement to the finished batch. Equipment photos and one sample are not enough. Check the production path, the control evidence, and the final coil identity.

How to Audit a PPGI Factory Through One Order
Use one connected evidence path. Each control point should link back to the same approved order.

01 Confirm the Order
Check the approved sample and written specification.

02 Check First Output
Compare the first coil or sheet with the approved reference.

03 Monitor the Run
Review the agreed fields while bulk production continues.

04 Verify the Batch
Link finished-coil results to labels or batch records.
Check Whether the Line Fits Your Product
Advertised capacity does not prove product fit. Match the line to the actual coil, paint, surface, and later forming need.
Material Route
The shown line handles the required substrate and metallic-coating route.
Coil Range
The line accepts the confirmed width, thickness basis, ID, and coil weight.
Surface Requirement
The process fits the approved paint, color, gloss, and finish.
Control Evidence
The factory can show how the target fields are checked and identified.
The ISO 9001 overview includes monitoring and measurement within quality management requirements.
A Factory Tour Is Not a Production Audit
Factory Tour
Shows that the site and equipment exist.
- General workshop
- Visible equipment
- Product display
Production Audit
Shows how the target order is controlled.
- Approved requirements
- Real control points
- Finished-batch evidence
PPGI.LTD's five-step color control process is one example. Thickness, metallic coating, and mechanical properties still need their own evidence.
