The scenario
An injection molding cell produces inspection covers through clamping, injection, cooling, ejection, and quality inspection, with failed parts sent to rework rather than scrap.
What is in this drawing
Read the decisions behind it.
01
Model quality inspection as two competing transitions to represent pass/fail outcomes
02
Add a rework loop from rejected parts back to raw material
03
Keep the final passed-inspection place as a sink with no outgoing transitions
Use this pattern for discrete manufacturing processes with sequential stages, branch quality gates, and rework loops.
