Supplier and Process Quality Audit for Foundries (Sand Casting, Precision Casting, Die Casting): HTTP Interfaces and External Systems

Data for this category primarily comes from ERP material master data, melting furnaces and thermometers, spectrometers, MES heat records, mold

What data for this category looks like

Data for this category primarily comes from ERP material master data, melting furnaces and thermometers, spectrometers, MES heat records, mold management systems, and customer technical drawings. Daily documents include foundry process cards, batching lists, heat records, mold histories, first article inspection records, material reports, and nonconforming product review forms.

Data updates are triggered per heat, batch, or daily. Core fields include alloy batching ratio, melting temperature, pouring parameters, heat number, mold cycle number, and defect type. Field units include degrees Celsius, seconds, and similar units.

Constraints for HTTP Interfaces and External Systems

The high-frequency updates and multi-source heterogeneous nature of this category’s data requires HTTP interfaces to support response times from milliseconds to seconds. This adapts to different input parameter formats of equipment such as melting furnaces and spectrometers, and management systems such as ERP and MES.

Strong correlations between core fields (for example, heat number corresponding to batching records, mold cycle number linked to defect data) require interfaces to support associated parameter passing. Identity authentication must be completed via the Authorization field to prevent unauthorized tampering or leakage of quality data.

Additionally, quality issues have serious consequences. Interfaces must include built-in timeout circuit breaking and failure retry logic to avoid interrupting audit workflows due to interface exceptions.

How to Configure

This configuration logic applies to FastGPT v4.17.0.

Config ItemRecommended ValueRationale
AuthorizationBearer {foundry workshop-specific authentication token}Adapts to standard authentication logic for industrial equipment and management systems, ensuring secure interface access
variables{"filter heat": "recent 3-day heats", "focus defects": ["shrinkage porosity", "gas porosity", "slag inclusion"]}Matches core business requirements for filtering data by time and defect type during foundry supplier audits
responseDataReturn heat ID, alloy composition report, nonconforming product review form numberReturns streamlined fields only to reduce interface transmission load, adapting to scenarios with limited workshop network bandwidth
Interface timeout period30–60 secondsAdapts to data upload delays from melting furnaces, spectrometers, and other equipment, avoiding call failures due to slow device responses
Failure retry count2 timesAddresses temporary network fluctuations or system lag, reducing audit workflow interruptions caused by single interface exceptions

Three Common Mistakes

  • Interface calls return the 401 Unauthorized status code, indicating authentication failure. The cause is incorrect configuration of the token format in the Authorization field, missing the Bearer prefix, or using an expired authentication token.
  • The responseData field returned by the interface is empty, and no quality data for the corresponding heat is obtained. The cause is failure to pass correct filtering parameters in variables, so the interface does not match qualifying heat records.
  • Interface calls time out, and data cannot be pulled. The cause is that the configured timeout period is shorter than the data upload duration of melting equipment, failing to adapt to device response characteristics of foundry scenarios.

How to Confirm Configuration is Complete

  • Call the configured HTTP interface, check if responseData includes preset core fields such as heat ID and alloy composition report.
  • Pass preset variables filtering parameters, verify if the interface returns quality data matching the filtering conditions.
  • Simulate temporary network fluctuations, verify if the interface completes failure retries according to the configured retry count.
  • Check interface authentication logs, confirm that the token in the Authorization field is correctly identified, with no unauthorized access records.
