Quality & Inspection
Quality you can verify
ISO 9001 process control, in-process and final inspection, material certificates and fin-safe packaging — so the parts arriving at your dock match the drawing. We treat documentation as part of the part, not an afterthought.
How quality is built in
Quality control starts before metal moves. At quoting we write a quality plan from your drawing: which dimensions are critical, which finish band applies, and what evidence ships with the order. During production, first-article inspection sets the baseline, in-process gauging keeps the run centered, and final inspection confirms the lot against the plan. That sequence — plan, first article, in-process, final — is what makes a reorder repeatable.
For regulated programs we can align to ISO 13485-controlled processes: material certificates, full traceability and controlled handling written into the quality plan rather than assumed. Tell us the standard and we scope the controls up front.
What ships with your order
- Material certificate (EN 10204 3.1)
- First-article / inspection report
- RoHS / REACH declaration on request
- Coating-thickness and salt-spray records where specified
- Leak-test record for cold plates / welded seals
Inspection stages
First-article
Full dimensional check of the first parts against the drawing; the baseline every reorder is measured against.
In-process
Gauging and SPC on critical dimensions during the run, so drift is caught before it becomes scrap.
Final
CMM, profile gauges, coating thickness and salt-spray validation on the finished lot.
Fin-safe packing
Protective spacing and custom crates so delicate fins and machined faces arrive undamaged.
Inspection equipment (typical)
| Equipment | Use |
|---|---|
| CMM | Critical dimension verification |
| Profile projector / gauges | Cross-section conformance |
| Coating thickness gauge | Anodize / powder film |
| Salt-spray chamber | Corrosion validation |
| Helium leak tester | Cold plate / welded seals (≤1×10⁻⁹ mbar·L/s typical) |
| Surface roughness tester | Ra verification on machined faces |
Equipment is drawn from our line and the Foshan cluster test houses; we name the exact checks in your quality plan.
Certifications & compliance
Frequently asked questions
What documents accompany a shipment?
A material certificate (EN 10204 3.1) and an inspection report are standard. On request we add RoHS/REACH declarations, coating-thickness and salt-spray records, and a leak-test record for cold plates or welded seals. Tell us your program's documentation list and we build it into the quality plan.
Are you ISO 13485 certified?
We run ISO 9001 and can align to ISO 13485-controlled processes for medical programs — material certs, traceability and controlled handling written into the quality plan. We do not assume a certification we have not been audited against; raise the standard early so the controls match.
How do you test liquid cold plates for leaks?
Every plate is 100% helium mass-spectrometer leak tested to ≤1×10⁻⁹ mbar·L/s, plus hydrostatic pressure testing above the working pressure. We set the test pressure to your spec, so a plate that passes is safe in your loop.
Can you hold tight tolerances?
Standard extrusion follows EN 755-9; machined features follow ISO 2768 (fine on request) with positioning to ±0.01 mm. Critical features are machined from true datums after extrusion. The tolerances guide shows typical bands.
How do you protect delicate fins in transit?
Fin-safe packing: protective spacing between parts, edge protection and custom crates sized to the lot, so thin fins and machined faces are not crushed or scuffed in transit. We design the pack with the part, not after.
