What this category of data looks like
This category of data covers the full injection molding process. Sources include resin batch property sheets, injection molding machine operating parameters, mold temperature controller data, production MES systems, first-piece inspection forms, material change and machine cleaning records, and more. Daily documents include injection molding process cards, raw material drying logs, mold history, patrol inspection forms, and more. Fields cover filling, holding, cooling window parameters, raw material moisture content, recycled material ratio, mold temperature, molding cycle, and more. Units include degrees Celsius, megapascals, seconds, and more. Data updates trigger with each production batch, mold change, material change, and shift patrols. There is no fixed schedule, and updates occur in real time alongside production milestones.
What constraints these characteristics impose on workflow orchestration
Data sources for this category are scattered and tied to production milestones. Workflow orchestration must support pulling data from multiple sources, covering inputs in different formats such as equipment parameters, system logs, and paper-based patrol records. Data updates trigger with production batches, mold changes, material changes, and shift patrols. Workflows must support executing nodes triggered by production events. Professional fields such as filling, holding, cooling window parameters and recycled material ratio require precise matching of business semantics. Workflow nodes must be configured with professional term parsing rules. Since errors may lead to batch defects and safety risks, workflows must add parameter verification steps to prevent incorrect parameters from entering production links.
How to set configurations
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
variables | Bind fields including raw material moisture content, recycled material ratio, etc. | Cover core business parameters of this category, compatible with FastGPT v4.17.0 variable binding functionality |
| Knowledge base selection node | Allow manual selection of the knowledge base for the corresponding production batch | Adapt to business requirements for switching data by production batch |
| Document parsing node | Enable professional term recognition mode | Adapt to professional semantic parsing of injection molding process parameters |
| Context length | 800–1200 characters | Accommodate complete parameter content for a single batch of injection molding processes |
| Maximum number of retrieved entries | Top 5 | Focus on core process and inspection data for the current production batch |
| Trigger condition | Trigger by mold change or material change events | Match the rhythm of data updates tied to production milestones for this category |
Three common errors
- Missing document output node: No archivable process document is generated after workflow execution. This occurs because no document generation node is added, and model output is not mapped to the standard format of injection molding process cards.
- No workflow response during local model deployment: No result is returned in the chat window or workflow after uploading raw material drying logs or process card attachments. This occurs because no adaptation parameters for the local model node are configured, or the attachment parsing permission switch is not enabled.
- Incorrect document parsing node configuration leads to unreadable files: Parsed fields are empty or error messages are returned. This occurs because professional term recognition mode is not enabled, or the field structure of injection molding documents is not matched.
How to confirm correct configuration
- Manually upload an injection molding process card attachment, trigger workflow execution, and check if parsed fields include core parameters such as filling, holding, cooling window parameters and raw material moisture content.
- Configure the knowledge base selection node, switch knowledge bases for different batches, and verify that the workflow correctly calls content from the corresponding knowledge base.
- Simulate a mold change event to trigger the workflow, check that nodes execute according to preset rules with no abnormal errors.
- After running the workflow, check that an output product conforming to the injection molding process document format is generated.
