| 3 | Review Equipment & Production Capacity | Assess technical capability and scalability | Request machine list, production line photos, and monthly output data. Cross-check with ERP/MES system reports if available. |
| 4 | Request Product-Specific Certifications | Ensure compliance with international standards | Verify ISO 9001, CE, and material certifications (e.g., 6063-T5 aluminum). Request test reports for load testing, corrosion resistance, and cycle durability. |
| 5 | Evaluate R&D & Engineering Support | Confirm in-house design and customization capability | Review engineering team credentials, CAD/CAM software usage, and sample development timelines. Request DFM (Design for Manufacturing) feedback on your hinge specs. |
| 6 | Audit Quality Control Processes | Ensure consistent product quality | Inspect QC documentation: incoming material checks, in-process inspections, final audit reports, and AQL sampling standards (e.g., MIL-STD-105E). |
| 7 | Verify Export History & Client References | Confirm international trade experience | Request export invoices (redacted), shipping manifests, and 3 verifiable client references (preferably in EU/US markets). Conduct reference calls. |
How to Distinguish Between a Trading Company and a Factory
| Indicator | Factory (Recommended) | Trading Company (Use with Caution) |
|---|---|---|
| Business License | Lists “manufacturing” or “production” in scope | Lists “trading,” “import/export,” or “sales” only |
| Facility Ownership | Owns or leases factory premises (confirmed via audit) | No physical production site; uses subcontractors |
| Production Equipment | On-site CNC, stamping, surface treatment lines | No machinery; relies on partner factories |
| Staff Structure | Employs engineers, QC inspectors, production supervisors | Sales and logistics-focused team only |
| Pricing Transparency | Can break down costs (material, labor, overhead) | Provides lump-sum quotes without cost structure |
| Lead Times | Direct control over production scheduling | Dependent on factory availability; longer lead times |
| Customization Ability | Offers mold/tooling investment, OEM/ODM services | Limited to catalog items or minor modifications |
| Communication | Direct access to technical and production teams | Single point of contact; delays in technical queries |
Strategic Note: While trading companies can be efficient for low-volume or one-time orders, factories offer better cost control, quality assurance, and long-term partnership potential for hinge components requiring precision engineering.
Red Flags to Avoid
| Red Flag | Risk Implication | Recommended Action |
|---|---|---|
