Certified Precision Manufacturing — Auditable, Traceable, Compliant
For 26 years, Xiamen Goldcattle has built custom metal and plastic parts for regulated industries worldwide. Every order is backed by an in-house quality system, 100% material traceability, and certificates you can verify.
1. Quality Management System
Goldcattle operates a vertically integrated quality system — no outsourcing, no black boxes. All processes are controlled in-house under the following certifications:
| Certification | Scope | Applies to |
|---|---|---|
| ISO 9001 | Quality Management System | All processes |
| IATF 16949 | Automotive QMS | CNC, die casting, molding |
| AS9100 (D) | Aerospace QMS | CNC machining |
| ISO 13485 | Medical device QMS | CNC, molding |
| SGS | Verified supplier | Company |
| RoHS | Hazardous substance compliance | Materials & parts |
| Rmbond | Material compliance | Materials |
Certificate wall
The certifications below cover our full service range — from CNC machining and die casting to injection molding, sheet metal and 3D printing — and span the industries we serve (automotive, aerospace, medical, electronics, machinery). Each cert is current, issued by an accredited body, and covers the Xiamen facility where your parts are produced. Cross-industry coverage means you can qualify one supplier for multiple product lines, instead of auditing a new shop for every change.
2. Industry & Product Compliance
We align our process controls to the regulatory demands of your industry. Tell us your target standard and we supply the matching documentation.
| Industry | Applicable standards & directives | Documentation we provide |
|---|---|---|
| Automotive | IATF 16949, PPAP, APQP | PPAP Level 3, FAI, CoC |
| Medical | ISO 13485, FDA-aligned records | Material cert, full traceability |
| Aerospace | AS9100, NADCAP-on-request | FAI (AS9102), material cert |
| Electronics | RoHS 3, REACH SVHC | RoHS / REACH certificates |
| Marine / Industrial | ISO 9001, custom specs | Dimensional & material reports |
RoHS and REACH compliance certificates are issued per order against your specified target standard (e.g., RoHS 3, REACH SVHC). Conflict-minerals and material declarations available on request.
3. Inspection & Testing Capabilities
Our in-house metrology lab verifies material composition and dimensions on every critical feature.
| Equipment | Purpose |
|---|---|
| Coordinate Measuring Machine (CMM) | Dimensional inspection, ±0.005 mm |
| XRF analyzer | Material composition verification |
| Surface roughness tester | Ra 0.4 μm verification |
| Hardness tester | Material property check |
| Salt spray chamber | Corrosion / plating validation |
| Tensile tester | Mechanical property validation |
4. Quality Control Workflow
Every part passes four controlled gates before shipment. In-process checks catch deviations early — not after the lot is finished.
Incoming material verified with mill certs and XRF spot checks.
In-process CMM checks on first-off and critical features.
Full dimensional and visual inspection per drawing.
Final audit, CoC issued, lot released for shipment.
Sampling-based inspection
For batch orders we apply statistical sampling (ANSI/ASQ Z1.4 style) so verification stays reliable without inspecting every piece:
| Lot size | Sample size |
|---|---|
| 1 – 50 | 1 |
| 51 – 90 | 2 |
| 91 – 150 | 3 |
| 151 – 280 | 5 |
| 281 – 500 | 8 |
| 501 – 1,200 | 13 |
| 1,201 – 3,200 | 20 |
Tighter 100% inspection is applied for aerospace, medical and low-volume critical runs.
5. Material Certificates & Traceability
100% of raw materials are lot-tracked from receiving to finished part. Every shipment includes a full size report and material certificate.
Mill test certificates
Every alloy and plastic is supplied with a verified material cert and lot number.
Lot traceability
Batch records link raw material → machine → operator → inspection result.
Full size reports
Dimensional data and CoC delivered with the parts, not "on request later".
"Goldcattle delivered ±0.005 mm machined components with full material certificates that passed our regulatory audit. Their traceability was exactly what our medical device needed." — Sarah K., Medical Tech Startup Founder

7. Frequently Asked Questions
What certifications does Goldcattle hold?
We are certified to ISO 9001, IATF 16949 (automotive), AS9100 (aerospace), and ISO 13485 (medical), plus SGS, RoHS and Rmbond compliance. Certificates are available on request.
Can you provide PPAP and FAI documentation?
Yes. We support PPAP (typically Level 3) and First Article Inspection (FAI, AS9102 format on request) with full dimensional and material reports.
How do you ensure material traceability?
100% of raw materials are accompanied by mill test certificates and lot-tracked from incoming inspection through final shipment. We provide full size reports and material certificates on every order.
Are your parts RoHS and REACH compliant?
Yes. Commonly used alloys and engineering plastics comply with RoHS and REACH directives. Compliance certificates are provided on request specifying your target standard (e.g., RoHS 3, REACH SVHC).
Do you support automotive IATF 16949 requirements?
Yes. Our quality system is built to IATF 16949 for automotive supply, including controlled processes, PPAP and traceability.
