Custom metal parts cases show how an order actually flows. Each case below follows the same path: RFQ, DFM, pilot, delivery. Weizhi (Hebei Weizhi Import And Export Co., Ltd.) runs this path for the group factory operating since 1999. Weizhi handles the RFQ, documentation and delivery interface. The group factory in Nanpi handles production. That split keeps communication fast and standards consistent.
How to Read These Cases
- Part name and its use.
- Key specs that drove the design.
- Process chain and documents.
- Outcome: what changed for the customer.
Case numbers are stated once and used consistently. A spec in the index matches the case detail above it. If your drawing differs, the delta decides the lead time. That is how case data stays quotable.
How Fresh Is This Page
This page updates when a new case reaches stable volume. Case specs themselves never change. Contact details follow the site’s main pages.

Case Data Index
| Case | Material | Key spec | Outcome |
|---|---|---|---|
| Insulated cabinet | 6061 Al + 304 SS | 150 kg load, 8 h insulation | Long-term bulk supply |

Document Flow by Stage
Every case follows one document flow. Nothing arrives without its paper trail.
| Stage | Document you receive |
|---|---|
| Quotation | Stage-by-stage lead time, MOQ and tooling note |
| Pilot | Dimension report for key features |
| Production | Mill certificate (EN 10204 Type 3.1) per batch |
| Pre-shipment | Inspection report; FAI per AS9102 on request |
| Shipment | Packing list + labeled cartons |
The same flow applies to a 10-piece pilot and a monthly volume order.
Application Matrix by Industry
| Industry | Typical parts we deliver |
|---|---|
| Medical / healthcare | 304 / 316 housings, trays |
| Electronics | Enclosures, brackets, clips |
| Automotive | Brackets, frames, supports |
| Construction tools | Tool components, frames |
| Energy | Panels, housings, mounts |
| Marine & shipbuilding | Hardware, frames, covers |
| Farming equipment | Frames, brackets, panels |
| Fire fighting equipment | Hardware, brackets, bodies |
| Packaging | Clips, brackets, hardware |
| Home gardening | Hardware, tool components |

The matrix is a starting point. The final spec always comes from your drawing. Across all industries the part families stay the same: plates, frames, boxes and shells, clips, brackets and hardware.
Matching Your Part to a Case
- Send a photo and the function. We name the closest case.
- Send a drawing and we reuse its known process data.
- Send a part sample and we reverse-check the dimensions.
Each route ends with the same deliverable: a reference case, a fit assessment and a stage-by-stage lead time.
Service Flow Behind the Cases
- 5-minute DFM check on received drawings.
- Free sample within 72 h for qualified projects.
- EN 10204 Type 3.1 certificate per batch.
- FAI report per AS9102 on request.
- Lead time reported by stage in the quotation.
Why Outcomes Matter
A lead time without an outcome is a promise. A tolerance without a report is a wish. Each case on this page pairs its spec with what we actually delivered. That pairing is what you should ask any supplier for.
What Your Case File Includes
- Mill certificates for all purchased material.
- Inspection report for critical dimensions.
