| Metering cylinder and fill range | A cylinder must operate appropriately across the planned quantities. | Compare the smallest and largest fills with the proposed cylinder; a wide range may call for a different cylinder or setup. |
| Hopper position and product feed | The product must reach the chamber without an unsuitable restriction or interruption. | Compare vertical or horizontal station layouts with the actual product path; include transfer and replenishment where needed. |
| Temperature control | Some formulations need a defined temperature to remain suitable for filling. | Separate the need for heating, temperature control and agitation; define each function in the chosen configuration. |
| Valve and nozzle | Product behavior and container access affect flow, cut-off and cleaning. | Match the formulation, opening and filling motion; specify any required shut-off or lifting function. |
| Heads, controls and container handling | More heads or different container motion change the station and its interfaces. | Review the selected layout and controls together; head count alone does not establish a production rate. |
| Utilities and changeover provisions | Air, electrical supply, working access and format changes affect installation and daily use. | Compare the actual utility requirements, working area and parts adjusted or changed between products. |
