Viscosity and temperature
Some products change dramatically with temperature or shear, so the feed and dosing route must match production conditions.
Bottle filling machinery
Viscous & Paste Bottle Filling Machines
Filling systems for creams, gels, sauces, adhesives and other thick products where feed method, valve design, nozzle cut-off and cleaning matter as much as the nominal fill volume.
Application fit
Where paste bottle fillers fit
The machine should be selected as a complete product-and-pack system, not from fill volume alone.
- Creams, gels, sauces, honey-like products and viscous liquids
- Products that string, tail or retain air during transfer
- Applications needing hopper feed, agitation or optional heat control
- Semi-automatic stations and automatic multi-nozzle lines
Viscous & Paste Bottle Filling Machines. The recommended configuration will be matched to your product, container, fill range and required output.
Specification priorities
Four decisions that shape the machine
The same nominal fill volume can require a very different solution when product behaviour, pack geometry or cleaning changes.
Particles and inclusions
Pieces, fibres or particulates affect valve bore, nozzle diameter, product path and whether a standard piston arrangement is suitable.
Nozzle cut-off
Shut-off, suck-back or positive cut-off helps control strings and keeps the bottle neck and conveyor clean.
Cleaning access
Hopper, cylinder, valve block, hose and nozzle should be considered as one product-contact system.
Filling routes
How the main configurations work
Use the filling principle as a shortlist, then verify it with the actual formulation and representative bottles. Headline technology names do not replace product trials.
| Configuration | Practical role |
|---|---|
| Piston volumetric | A measured cylinder stroke displaces a repeatable volume and can handle a broad viscosity range. |
| Rotor-lobe or positive-displacement pump | A controlled pumping route for products that need gentle transfer or a continuous supply. |
| Heated or mixed hopper | Can help keep temperature-sensitive products consistent where the formulation permits it. |
| Servo multi-head system | Recipe control, synchronised dosing and automatic bottle indexing for higher output requirements. |

Project route
From enquiry to production-ready specification
A structured review prevents the filler, bottle control and downstream machines from being specified in isolation.
Define the product
Confirm viscosity, foam, particles, temperature, compatibility and cleaning.
Validate the pack
Review bottles, necks, closures, labels and stability using representative samples.
Set the output
Agree batch size, target rate, operators, changeovers and future growth.
Confirm the line
Freeze layout, interfaces, utilities, guarding, tests, installation and training scope.

Viscous & Paste Bottle Filling Machines FAQs
Practical answers for early project planning.
What is the best filler for thick paste?
A piston or other positive-displacement route is often considered first, but the correct answer depends on viscosity at production temperature, particles, aeration, dose range and cleaning requirements.
Can the hopper be heated or mixed?
Representative volumetric systems can be configured with heated or mixed hoppers. Product suitability, temperature control, guarding and clean-down requirements must be confirmed.
How can stringing at the nozzle be controlled?
Correct nozzle bore, a positive shut-off or suck-back action, suitable fill speed and the distance between nozzle and product can reduce tails. Trials with the actual product and bottle are recommended.
Can one paste filler handle both small and large doses?
Possibly, but very wide fill ranges may require different cylinders, pumps, nozzles or recipes. Confirm the minimum, maximum and most common volumes at enquiry stage.
Send the product, bottle and output target.
Lancing Ltd can compare the practical bottle filling routes and confirm the right next step before quotation.
Bottle and nozzle fit
Plan viscous filling around opening size, product tailing and bottle support
A paste filler needs more than enough force to move the product. The pack must accept the nozzle, remain stable during the dose and leave the filling position without strings or drips reaching the shoulder, thread or label panel.
Neck clearance
Check the smallest opening and shoulder geometry against the nozzle body, shut-off mechanism and any required insertion.
Bottle restraint
Assess whether the empty container needs a nest, guide, puck or controlled stop while the product enters.
Clean release
Review suck-back, rotary or positive shut-off options only after seeing how the real product tails at production temperature.
Evidence to include with the enquiry
- Viscosity and temperature range, including startup condition
- Largest particles or inclusions and their concentration
- Bottle opening and internal restrictions
- Required fill weight or volume and product giveaway priorities
- Cleaning, strip-down and product recovery expectations
Use the bottle-led planning guides
These guides isolate the pack variables that can change an otherwise suitable filling-machine route.

Positive-displacement route
When to assess a piston bottle filler
A piston system can suit pumpable products where a physical displacement, controlled product path and decisive nozzle cut-off are important. Confirm the practical cylinder range, valve path, product feed, particles, temperature, stringing and cleaning method.
The nozzle is only the final part of the path. Representative trials should include cylinder draw, valve transfer, discharge, stop and restart.
Edge cases to trial
- Minimum and maximum dose
- Coldest or most viscous normal condition
- Largest particle or most elastic product
- Smallest bottle neck and sensitive label area
- Normal clean, reassembly and first-off process
Verified semi-automatic example
Assess the LU-GT1V against the real paste or liquid
The LU-GT1V is a fully pneumatic hopper-fed route. Its reference modules cover 5–1000ml, but product behaviour, module selection, operator cycle and cleaning must be confirmed together.
- Trial minimum and maximum viscosity at normal temperature
- Check stringing, nozzle cut-off and bottle location
- Choose the fitted dose module around the real range
- Define hopper refill, drain-down and cleaning
