Why assembly deserves its own selection
Assembly links upstream and downstream; a mismatched cycle time drags the whole line, and unstable precision creates defects. Treat it as a standalone equipment decision.
Automatic vs semi-automatic
| Factor | Automatic | Semi-auto |
|---|---|---|
| Throughput | High, stable | Labor-paced |
| Changeover | Programmatic | Manual tuning |
| Cost | Higher capex | Lower capex |
Four parameters to confirm first
Product structure and tolerance, target cycle time, changeover frequency, inspection method — quantify these before discussing equipment.
