Meaning
Paper or digital routing documents that follow a batch of components through every stage of the manufacturing process provide the primary record of shop floor activity. A suigongdan identifies the raw material lot number and the specific operator who performed each transformation.
Document History
Maintaining a chronological record of production events allows auditors to verify that every required process step occurred in the correct order. The suigongdan prevents the skipping of heat treatment or surface finishing steps by requiring a sign off at each station.
Process Sequence
Manufacturing instructions printed on the form guide the movement of materials between work centers to ensure that sub assemblies arrive at the correct time. If a suigongdan is lost, the entire batch must be quarantined until the production history can be reconstructed through electronic logs.
Traceability Link
Product recall procedures in the Chinese market rely on these documents to isolate defective batches by identifying which machines processed a specific order. Linking the suigongdan to the final shipping invoice creates a chain of custody that satisfies the State Administration for Market Regulation. This linkage ensures that any consumer safety issue leads back to a specific shift or material supplier within hours.
