Quality Problem Traceability and Defect Analysis for Plastic Injection Molding: Model Access and Configuration

Data for this category comes from resin batches and property sheets, injection molding machine operating parameters, mold temperature controller data

What the data for this category looks like

Data for this category comes from resin batches and property sheets, injection molding machine operating parameters, mold temperature controller data, workshop MES systems, and dimensional and appearance inspection results. Daily associated documents include injection molding process cards, raw material drying records, mold history logs, first-piece inspection reports, patrol inspection records, and material change and machine cleaning records. Data updates trigger with each production batch, each mold or material change, and each shift. Fields include injection pressure, cavity temperature, raw material moisture content, mold cycle count, dimensional deviation values, and more. Units include MPa, ℃, %, times, millimeters, and others.

Constraints for Model Access and Configuration

Data update nodes are scattered and update frequency is high. Model access and configuration must support incremental data synchronization triggered by production nodes, to avoid resource consumption from full data pulls. Multi-source heterogeneous data formats are used, including direct device parameters, digitized paper records, and inspection reports. The configuration link must adapt to multi-format field parsing and retain original field mappings. The scale of parameter sets for single-batch production varies widely. Context carrying capacity must be limited to prevent model processing timeouts. Defect analysis requires association with historical data such as mold history logs and raw material batches. The configuration must clearly define the recall scope and association rules for historical data.

Configuration Parameters

AIPROXY_API_ENDPOINTProxy address deployed on the enterprise intranetEnsure secure transmission of workshop intranet production data, avoiding public network exposure risks

Workflow/API tool selectionautoAllow the model to independently choose whether to call tools to parse injection molding process parameters and inspection data

Three Common Configuration Errors

  • Phenomenon: The model returns a 503 status code, with a prompt that no available text-embedding model exists under the default group. Cause: No dedicated model group is configured for the injection molding scenario, and resource competition occurs when reusing the general group.
  • Phenomenon: Defect analysis results generated by the model have incorrect or missing units for injection pressure parameters, or fail to associate corresponding raw material batch information. Cause: Original data field mapping rules are not retained during configuration, leading to arbitrary parameter unit conversion or omitted associated fields.
  • Phenomenon: Model comparison experiments and ablation analysis cannot be performed, and the impact of different configurations on defect analysis results cannot be verified. Cause: No multi-model switching entry is reserved in the model access configuration, and no historical production dataset for testing is associated.

How to Verify Successful Configuration

  • Submit test data for a single batch of injection molding production, and check whether the defect analysis results returned by the model include associated information such as mold history logs and raw material batches.
  • Call the model interface, and confirm that the returned status code is 200, with no 503 or other abnormal errors.
  • Configure multiple sets of different temperature values, compare the rigor of the analysis results, and determine the value range that meets business requirements.
  • Switch between different model groups, and verify that the corresponding models can be called normally to complete the defect analysis task.
