| 6 | Obtain Customer References & Case Studies | Validate track record in alumina ceramics. | Request 2–3 verifiable B2B clients (preferably in electronics, semiconductor, or industrial automation). |
| 7 | Test Sample Rigorously | Confirm performance meets specifications. | Conduct third-party lab testing for purity, flexural strength, and dimensional accuracy per ISO 6474 or ASTM F624. |
2. How to Distinguish Between a Trading Company and a Factory
| Indicator | Factory (Recommended for Long-Term Sourcing) | Trading Company (Higher Risk, Lower Control) |
|---|---|---|
| Facility Ownership | Owns and operates production equipment on-site. | No production equipment; uses subcontractors. |
| Lead Times | Can provide realistic production timelines based on machine capacity. | Often vague or overly optimistic; dependent on factory availability. |
| Pricing Structure | Transparent cost breakdown (material, labor, overhead). | May lack granularity; higher margin baked in. |
| Technical Expertise | Engineers on staff; can discuss sintering curves, grain size control. | Limited technical depth; defers to factory. |
| MOQ Flexibility | Can adjust MOQ based on line capacity. | MOQ dictated by partner factory; less flexible. |
| Factory Address | Industrial zone location (e.g., Zibo, Yixing, Dongguan). | Office-only address in commercial district (e.g., Shanghai Pudong). |
| Website & Marketing | Shows machinery, production lines, R&D labs. | Focuses on product catalog and global shipping. |
| Response to On-Site Audit | Welcomes or initiates audits. | Resists or delays audit requests. |
