Flow & quantity control
Include density, viscosity, foaming and air entrainment in the review. Converting a target mass into volume requires the product density at the relevant temperature.
Pump & nozzle selection
Suitable pump, piston or alternative measurement arrangements are assessed with the product. Trials check nozzle residue, dripping and the end of the fill. No single method is assumed suitable for every lotion.
Containers & changeover
Narrow-neck bottles, open containers and pump assemblies require different access. Plan guide, support and nozzle-height changes. The pump dip tube and tightening method are included in closure design.
Batches & cleaning
For fragrance or colour changes, define how the product path is cleaned, drained and prepared again. Cleaning procedure and material compatibility are confirmed with the actual formulation.
