Testing an Automatic Liquid Filling Machine With Your Own Liquid
Buyers should require a demonstration using their actual liquid and bottles, then compare filling accuracy, changeover, and cleaning against the reference range of 10–500 mL and 30–110 mm bottle diameter.
A practical buyer decision is whether to accept a demonstration run only with the supplier's sample liquid or to insist on a trial using your own product and bottles. Because the machine is a single-head rotor pump filler for packaging liquids, the material's viscosity, foaming tendency, and residue behavior can change how the run performs, so the trial should mirror your normal container and fill size.
In the request for quotation, ask the supplier to state the reference filling volume and bottle diameter they intend to demonstrate, noting that the catalog values of 10–500 mL and 30–110 mm are customizable reference figures rather than guarantees for every supplied model. Ask how many consecutive fills the demonstration will include, how fill-to-fill variation will be recorded, and whether the same pump settings can handle your smallest and largest planned volumes. During the demonstration, observe changeover between bottle sizes and the cleaning routine for the pump and product path.
Before requesting a quote, confirm with the supplier which liquid and bottle samples you must provide, how the trial results will be documented, and whether the demonstrated configuration matches the model you intend to order.
