What this category's data looks like
This category covers the full production process of injection molded parts, automotive interiors, home appliances, and medical plastic components. Daily documents include injection molding process cards, raw material drying records, mold history records, first article inspection reports, patrol inspection records, and material change and machine cleaning records. Data sources include resin batch and property sheets, injection molding machine operating parameters, mold temperature controller data, MES systems, and dimensional and appearance inspection results. Data updates trigger with each production batch, each mold or material change, and each shift. Each document includes core fields such as resin batch number, mold temperature setpoint, holding pressure duration, and inspection tolerances.
What constraints these characteristics impose on workflow orchestration
Data updates occur with each batch, mold or material change, and each shift. The workflow must support dynamically pulling dedicated documents for the corresponding batch based on trigger nodes. Multi-source data has significant format differences. Uniform format conversion steps must be configured during orchestration to adapt to parameter files exported by different devices. Documents such as mold history records and raw material drying records are closely linked. The workflow must support cross-node variable association calls to ensure data linkage across different stages. Production data has strict timeliness requirements. The workflow must set reasonable timeout thresholds to prevent task interruptions caused by delayed data synchronization. Errors in injection molding can directly lead to batch defects or safety issues. The workflow must configure failure retries and exception alert links to ensure data accuracy.
How to set configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Global variable settings | Bind variables by production batch | Adapt to dynamically updated data such as resin batch and mold temperature parameters for each batch |
| Workflow trigger node | Trigger by mold or material change events | Match the rhythm of data updates for this category triggered by mold and material changes |
| Knowledge base retrieval scope | Bind historical documents for the corresponding mold | Narrow the retrieval scope to improve result accuracy |
| Timeout threshold | 600 seconds | Cover the average time required for multi-source data pulling and format conversion |
| Number of failure retries | 2 times | Avoid task interruptions caused by single data synchronization exceptions |
| Node ID configuration | Use nodeId to associate with the mold history record node | Implement cross-node document association calls |
Three common mistakes
- Phenomenon: The AI chat module in the workflow returns empty results or prompts that relevant documents cannot be found. Cause: The file link to exclusive documents such as injection molding process cards and mold history records is not configured correctly, or the user's question does not limit the injection molding-related scenario.
- Phenomenon: The target knowledge base cannot be selected correctly when assigning global variables, and parameter format errors are returned. Cause:
variablesis not used as required to bind the knowledge base ID, or the input knowledge base identifier format does not meet system requirements. - Phenomenon: The workflow execution times out, or the task status remains in the running state. Cause: A reasonable timeout threshold is not set, or the failure retry mechanism is not configured, causing the task to fail to automatically recover when a single node has an exception.
How to confirm the configuration is correct
This document is written based on FastGPT v4.17.0.
- Trigger a simulated mold or material change event, check whether the workflow automatically pulls the raw material drying records and injection molding process cards for the corresponding batch.
- View the global variable list, confirm that the relevant parameters of the current production batch are bound in
variables. - Call the knowledge base retrieval node, verify that the returned results only include the historical documents of the current mold and the production data of the current batch.
- Simulate a single data synchronization exception, check whether the workflow triggers failure retries and exception alerts.
