A liquid filling machine should be chosen around the actual liquid and container together. A system that handles one free-flowing product may need a different configuration for a foaming, viscous or particulate product. Describe the product accurately before comparing machine offers.
Which liquid properties affect the enquiry?
Provide the product name, its behaviour at the intended filling temperature and whether it foams, drips or contains particles. Where available, share the relevant product and cleaning information with the supplier. Do not assume material compatibility or a particular filling principle from the machine's appearance.
For a six-head liquid filling machine, ask which product types and fill ranges the quoted model supports. The number of heads alone does not define accuracy, usable output or the cleaning process.
What container information is needed?
Supply minimum and maximum bottle dimensions, neck opening, material and target fill quantity. Include the lightest or least stable container. Explain whether containers arrive empty on a conveyor, are manually placed or form part of an automatic liquid filling line.
Ask about bottle positioning, nozzle arrangement, missing-bottle handling and drip management in the actual proposal. Clarify which functions and line interfaces are included instead of treating the word automatic as a complete scope description.
How should accuracy and capacity be compared?
- Agree a measurement method suitable for the product.
- Test each filling position with production bottles and liquid.
- Record accepted bottles, rejects and elapsed running time.
- Include replenishment, routine stops and format changes.
What should be settled before purchase?
Confirm contact materials, cleaning method, utilities and the full supply boundary with technical consultation. Use the companion fill consistency guide to plan how settings and results will be documented. Any performance figure should be tied to the product, fill range and trial conditions under which it was demonstrated.
