In OEM manufacturing, quality isn’t optional — it’s essential. For international clients outsourcing custom metal fabrication, consistent and transparent quality control (QC) processes are the backbone of trust.
At HD Mechanical Vietnam, we implement a comprehensive, multi-step QC system that ensures every metal component we ship meets your specifications — every time.
Why Quality Control Matters in OEM Metal Fabrication
Precision Is Key in Custom Parts
Whether it’s a mailbox housing, metal leg, or garden edging, even slight dimensional errors can cause:
-
Fitment issues in assembly lines
-
Delays in downstream processes
-
Rejected shipments and added cost
Cost of Poor Quality
Errors in metal fabrication can lead to:
-
Scrapping large volumes
-
Shipping rework components
-
Damaged client relationships
A strong QC process helps prevent all of the above.
Our Quality Control Process at HD Mechanical Vietnam
1. Dimensional Measurement
Every critical dimension is inspected using:
-
Vernier calipers and micrometers
-
Laser measurement (for longer parts)
-
Custom jigs for fitment testing
-
Measurements are documented and traceable per batch.
2. Welding Inspection
For welded products like raised garden beds or metal frames:
-
Visual inspection for burn marks, spatter, porosity
-
Weld bead consistency & strength check
-
Structural alignment confirmation using fixtures
3. Surface Finish Inspection
Before powder coating or after polishing:
-
Check for scratches, dents, tool marks
-
Surface smoothness verified
-
Powder-coat adhesion tested via tape or impact test
4. First Article Inspection (FAI)
Before mass production, we send a first approved sample (FAI) with:
-
Full dimension report
-
Photos or videos
-
Optional live inspection via video call
5. Final Pre-shipment QC
Before export:
-
Random sampling based on AQL standards
-
Confirm packing per spec
-
Label, barcode, and document check
