Routing
Each step recovers its work centre's rate for the hours run, and overhead is applied on top. That is the conversion cost inside WIP.
| Seq | Work centre | Operation | Hours | Rate /hr | Recovered |
|---|---|---|---|---|---|
| 10 | RX-01 Reaction Vessel 1 (fusion) | Direct fusion with stearic acid at 135°C | 3.3 | $380.00 | $1,254 |
| 20 | DR-02 Flash Dryer | Flash dry and cool | 4.8 | $195.00 | $936 |
| 30 | PK-01 Packing Line (20 kg sacks & 500 kg FIBC) | Pack to 500 kg FIBC / 20 kg sack | 1.1 | $185.00 | $204 |
