What the data for this category looks like
This category of data comes from the full project lifecycle of injection molding, stamping, and die-casting mold enterprises. Daily documents include mold design task sheets, DFM reports, part drawings, machining process cards, trial mold reports, mold modification notices, and mold records. Data sources include customer product models, mold flow/forming simulation files, CAD/CAM source files, machining and measurement data, and trial mold sample information. Updates are managed per individual project, with synchronized updates following each trial mold or mold modification. Each document is associated with exclusive fields such as mold number, part number, material grade, demolding angle (unit: degrees), shrinkage rate (unit: %), and more.
What constraints these characteristics impose on HTTP interfaces and external systems
The data characteristics of this category create multiple constraints for the HTTP interfaces and external systems link. First, data sources include non-plain text formats such as CAD/CAM source files and mold flow simulation results, so interfaces must support parsing multiple types of request bodies. Second, document updates trigger dynamically after trial molds or mold modifications, so interfaces must support batch calls by project to align with project-level document synchronization rhythms. Third, each document links to exclusive identifiers including mold number and part number, so interface requests must carry these fields to accurately match review documents for the corresponding project. Finally, the review process requires comparing consistency across multi-source documents, so interface response data must include structured fields ready for direct comparison.
How to set configurations
The following configurations are based on FastGPT v4.17.0.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Timeout configuration | 300–600 seconds | Mold project documents have large volume, so a single review request needs sufficient time to pull and compare multi-source data |
Authorization | Fixed secret key or dynamic token | Secure interface call permissions and prevent unauthorized access to external CAD or simulation systems |
variables | Carry mold number and part number | Accurately match review documents for the corresponding project and avoid data confusion across projects |
responseData | Extract structured review fields such as demolding angle and shrinkage rate | Simplify field comparison workflows for subsequent cross-review |
| Retry count | 2–3 times | Address temporary fluctuations in external systems and avoid review interruptions from single failed requests |
| Request body format | Adapt to JSON or binary as required by the external system | Compatibility with different types of external interfaces including CAD/CAM and mold flow simulation |
Three common errors
- Phenomenon: Interface requests return a 504 timeout status code, or requests are forcibly interrupted. Cause: Timeout configurations are not adjusted for mold document volume, and generic short timeout settings are used, which cannot complete multi-source document pulling and comparison.
- Phenomenon: Missing or mismatched review result fields return after calling the interface. Cause: Identifier parameters such as mold number and part number are not included in
variables, causing the external system to return document data for the wrong project. - Phenomenon: Multiple part drawings or process cards cannot be sent to the interface synchronously. Cause: Request bodies are not assembled in the format required by the external system, only metadata for a single document is sent, and multi-file parameter passing specifications are not followed.
How to confirm correct configuration
- Initiate a single project-level test request carrying the identifier parameters for the corresponding mold, and check if the interface response data includes the expected document fields.
- Simulate a temporary disconnection of the external system connection, and verify if the interface retries requests according to the configured retry count, and if requests complete normally after retries.
- Upload multiple documents from the same project, and check if the interface correctly identifies and associates metadata for all documents.
- View interface call logs to confirm the
Authorizationparameter is correctly carried, with no permission-related errors.
