Buyer guide
Start with real selection decisions.
Use this guide to move from general interest to a practical enquiry with the details needed to specify a machine.
The guide covers product methods, applications, quote details, troubleshooting, changeovers and line integration in practical production language.
Product behaviourViscosity, temperature, particulates, aeration, stringing, settling and whether the product changes during the day.
Fill requirementTarget fill volume, tolerance, dose range, container neck opening, headspace and whether the fill is by volume, level or weight.
Container and closureJar, bottle, tub, cartridge, pail or jerrycan dimensions, cap style, labelling area and pack stability on conveyors.
Production targetRequired bottles per minute or per hour, number of SKUs, changeover frequency, cleaning process and operator involvement.
| Step | Decision | Why it matters |
|---|---|---|
| 1 | Define the product | Viscosity, temperature, air entrapment, particles and stickiness decide the filling principle and nozzle setup. |
| 2 | Define the container | Neck size, height, material and stability affect fill accuracy, splashing, dripping and conveyor design. |
| 3 | Define the fill | Fill volume range, tolerance, headspace and presentation standard affect cylinder size and filling cycle. |
| 4 | Define the output | Batch size, BPM target and operator involvement decide semi-automatic versus automatic filling. |
| 5 | Define downstream equipment | Capping, labelling and coding need to match the filler speed and container handling method. |
Selection guide sections
Key areas to review before choosing a machine.
Product problem solving
Include sections on dripping, tailing, stringing, particles, hot fill, aeration, clean-down and product contact materials.
Quote preparation
Use the checklist so your first contact includes enough data to recommend a machine.
Next steps
Move from guide to machine options.
Semi-automatic paste fillers
Flexible piston filling for smaller batches, trials, contract packing and products where an operator places containers or controls each cycle.
View semi-auto route →
Automatic paste filling machines
Inline multi-nozzle filling for higher output, repeatable dosing and integration with conveyors, capping, labelling and coding.
View automatic route →
Piston paste fillers
Positive-displacement volumetric dosing for sauces, creams, gels, honey, sealants and similar viscous products.
Compare piston fillers →
Fill, cap and label integration
Plan the filler with closure handling, bottle stability, conveyor layout, labelling and end-of-line requirements from the start.
Plan line integration →Sauces and condiments
Ketchup, chutney, pesto, mayonnaise, dressings and viscous food sauces where drip control and clean jar presentation matter.
Sauce filling machines →Honey, jam and preserves
Thick, sticky and temperature-sensitive products that may need heated hoppers, careful cut-off and reliable fill repeatability.
Honey and jam fillers →Cosmetic creams and gels
Creams, masks, lotions, gels and personal-care products where cleanability, recipe control and closure integration are important.
Cream and gel filling →
Adhesives and sealants
Industrial pastes, waxes, greases, adhesives and sealants where viscosity, stringing and material compatibility must be reviewed.
Industrial paste filling →How do I choose a paste filling machine?
Start with product behaviour, fill volume, container, target output and cleaning needs. Then compare semi-automatic, automatic, piston and integrated line routes.
What is the best filling method for paste?
Many paste applications use positive-displacement filling such as piston or pump-based systems, but the best method depends on viscosity, particles, temperature, accuracy and clean-down.
How much information should I send before asking for a quote?
Send as much as possible: product samples or data, fill volume, container dimensions, closure, target output, cleaning needs, available utilities and site constraints.
Can I fill both liquids and pastes on one machine?
Sometimes, but it depends on the viscosity range, dose range, pump or piston route, nozzles, cleaning process and changeover needs.
What output can paste fillers achieve?
Output depends on product flow, fill volume, nozzle count, operator involvement, container handling and downstream line speed. A timed trial or specification review gives a more realistic answer.
Specification evidence
Turn a machine comparison into a written acceptance plan.
A good buying process records the assumptions behind fill range, accuracy, output and cleaning. That allows quotations to be compared on the same basis and reduces disputes when the machine is tested.
| Specification item | Minimum information | Acceptance evidence |
|---|---|---|
| Product | Name, temperature, viscosity behaviour, particles, aeration, settling, shear and material compatibility. | Representative sample and recorded condition during the test. |
| Fill range | Every production dose, tolerance and whether measured by volume or mass. | Sequential checks at agreed low, typical and high fills. |
| Pack | Dimensions, opening, stability, headspace, closure, label area and sample quantity. | Run the minimum and maximum formats with production components. |
| Output | Good packs per minute or hour, batch size, shift pattern and operator tasks. | Timed continuous run including normal container handling. |
| Cut-off | Acceptable drips, strings, neck cleanliness and product recovery. | Close-up inspection and reject count over the timed run. |
| Cleaning | Approved method, allergens or cross-contamination risks, maximum changeover and clean verification. | Demonstrated drain-down, strip-down, cleaning and restart. |
| Integration | Conveyor height, infeed, capper, labeller, coder, accumulation, controls and guarding. | Interface list and witnessed line sequence. |
Compare like with like
A low headline price can exclude product supply, change parts, nozzles, conveyors, guarding, installation or trials. Ask each supplier to respond to the same scope and identify every exclusion. Compare the number of validated SKUs and the cleaning method, not only head count.
Separate reference data from guarantees
Published fill ranges and reference accuracy can help shortlist equipment, but contractual performance should state product, dose, pack, speed and test method. A generic percentage or maximum speed without conditions should not be treated as a production guarantee.
Use a change-control list
Record what happens when product, temperature, fill volume, container, closure or line rate changes. Decide which changes need new parts, new trials or revised settings. This is especially important for contract packers running many SKUs.
Plan evidence retention
Keep approved samples, trial results, machine settings, product conditions, cleaning sequence and the final signed acceptance record. Those documents make future troubleshooting and repeat orders more reliable.
Buyer decision path
Move through product, dosing, pack, line and acceptance in that order.
Do not start with a model number. Start with the production problem, then compare the machine routes that can be tested against it.
1. Product and method
Compare piston and pump routes against the actual product path.
Technology comparison →2. Trial and cleaning
Agree sample conditions, acceptance checks and clean-down.
Product trial →3. Complete line
Confirm conveyors, closure, labelling, controls and good-pack output.

Questions for comparing quotations.
What is the most important performance condition to write down?
The exact product, product temperature, fill volume, container and test method. Without those, speed and accuracy figures are difficult to compare or reproduce.
Should the quotation include a product trial?
It is strongly useful for thick, particulate, stringy, aerated, temperature-sensitive or reactive products. The quotation should state the sample quantity and acceptance checks.
How should output be specified?
Specify accepted finished containers per minute or hour under defined conditions, including operator tasks and downstream equipment, rather than a theoretical machine cycle.
What exclusions should be checked?
Check product feed, tanks, pumps, change parts, nozzles, conveyors, guarding, capping, labelling, coding, installation, utilities, trials and cleaning equipment.
How can two suppliers’ accuracy claims be compared?
Require the same product, dose, sample count, temperature, speed and measurement method. Confirm whether the percentage is of target fill, full scale or another basis.
What should be retained after acceptance?
Keep the signed test record, samples or photographs, settings, change parts list, cleaning procedure, manuals and any deviations agreed during the trial.
