Liquid filling
Gravity, vacuum, volumetric, flowmeter or weighing approaches for different liquids and containers.
The dosing stage at the centre of the line
Automatic Filling Systems for Integrated Lines
Select filling technology by product behaviour, dose, accuracy, hygiene and throughput, then integrate it with the container and closure process.

Your production requirement
Choose the filling principle before choosing the machine size
A filling system is only suitable when its measuring principle, product-contact path and cycle match the application. The same nominal output can require very different equipment for water-like liquids, foaming products, creams, powders or granules.
Integration then turns the filler into a production line. Container presentation, no-container-no-fill logic, upstream supply, downstream spacing and cleaning access all influence the final arrangement.
Line architecture
Filling routes considered by application
The shortlist is built around what must be measured and how the product can be moved safely and repeatably.
Paste filling
Positive displacement and product-conditioning routes for creams, gels, sauces and other viscous products.
Powder dosing
Auger, volumetric or weighing approaches for powders and granules with dust and feed controls.
Specialist filling
Application-led options for carbonated, heated, hazardous-area or unusual container requirements.
Specification checklist
Define the filling duty in measurable terms
A specification should show the full operating range and the production conditions that affect it.
- Product properties and safety information
- Minimum and maximum fill quantities
- Required tolerance and verification method
- Containers per minute at normal operating conditions
- Cleaning, product change and contact-material requirements
- Tank, hopper, pump and upstream product-supply interfaces

Operational value
A filling stage that fits the wider process
Suitable measurement
The dosing principle is selected against product behaviour and accuracy rather than generic machine labels.
Practical sanitation
Product-contact parts, access and cleaning routes are considered with the operating team.
Balanced output
Nozzle count and cycle are matched to container supply and downstream capacity.

Straight answers
Frequently asked questions
How do I choose an automatic filling system?
Start with the product, dose range, accuracy, container, speed, cleaning and site requirements. These factors determine the suitable measuring and transfer principles.
Is more nozzles always better?
No. Nozzle count should match the filling cycle, container handling, product supply and downstream line speed. More nozzles can add complexity without improving real output.
Can filling systems save recipes?
Many automatic systems can use stored settings for agreed products and formats, but the available controls depend on the selected equipment and project scope.
Can a filler be supplied as part of a full line?
Yes. Filling can be integrated with rinsing, capping, sealing, labelling, coding, conveying and end-of-line equipment.

Specify product supply, dosing method and pack condition after filling
Filling-machine selection begins with the product and process conditions. Viscosity, particulates, aeration, foaming, temperature, settling, bulk density and product-supply stability can all change the practical filling method and the behaviour seen at the nozzle.
The line brief should also define what a correctly filled pack looks like for the next stage. Drips, strings, dust, product on the neck, static or unstable fill level may affect closure application, sealing, coding and label presentation.
| Input | Record | Decision affected |
|---|---|---|
| Product condition | Temperature, viscosity or flow behaviour, particulates, aeration and hazards | Measurement principle, product path, agitation and nozzle design |
| Supply method | IBC, tank, hopper, pump, vacuum transfer or manual loading | Feed controls, level management and responsibility boundary |
| Fill duty | Minimum and maximum amount, container range and quality method | Dosing range, head count, change parts and verification |
| Post-fill condition | Drip, foam, dust, settling time and neck cleanliness | Conveyor dwell, extraction, cleaning and downstream timing |
Project check
Use production-condition samples
Bench samples may not represent product temperature, air content or settling during a shift.
Project check
Define the measurement method
Agree how fill performance will be checked and which calibrated equipment or sampling plan is used.
Project check
Balance the feeder and filler
Product supply must replenish the dosing system without starving it or changing product condition.
