Production risks
Four issues to resolve before machine selection
These factors commonly change the dosing method, nozzle, product feed or line layout.
Stringing and cut-off
Nozzle shut-off, suck-back and nozzle movement determine whether the pack and machine stay clean.
Abrasive or filled products
Fillers and solids affect pump, seal, valve and hose wear.
Changeover and recovery
High-value or difficult-to-clean products make dead volume and product recovery commercially important.
Machine routes
Automatic filling options to compare
The best shortlist normally contains two or three practical routes tested against the real product and pack.
Heavy-duty piston filling
Positive displacement for products that can pass through a suitably sized valve and nozzle.
Rotor-lobe or gear-pump filling
A continuous pump route for selected viscous products, subject to shear and wear.
Heated filling system
Controlled temperature for waxes, hot melts or products whose viscosity falls when warmed.
Cartridge or pail line
Dedicated container handling, nozzle positioning and closing for industrial pack formats.

Information that makes a useful quotation
Send enough detail to assess dosing, product-contact design, container handling and downstream operations.
- Viscosity across the operating temperature
- Stringing, thixotropy and shear sensitivity
- Abrasive solids, fibres or particles
- Bulk supply vessel and transfer pressure
- Nozzle cut-off and product recovery
- Container opening and rim cleanliness
- Cleaning solvent or mechanical strip-down
- Closure, lid pressing or cartridge plunger

Practical answers
Adhesive and sealant filling machines FAQs
Answers are general guidance. Final suitability depends on product trials, containers and the confirmed machine specification.
Can an automatic filler handle very thick sealant?
Potentially, but the product may require a pressure-fed or ram-fed supply, large-bore product path and shut-off nozzle. A sample review is important.
How is adhesive stringing reduced?
Options include a positive shut-off nozzle, suck-back, nozzle lift, heated product path or a different dosing pump. The product's break-off behaviour should be tested.
Can abrasive paste be piston filled?
It may be possible, but seal, valve and cylinder wear must be assessed. Material choice and maintenance intervals become part of the specification.
Can the line fill cartridges automatically?
Yes, with project-specific cartridge handling, filling, air management and plunger or cap insertion. The cartridge format and product are needed for trials.

View optionsInclude standing time, curing behaviour and restart in an adhesive-filling brief
An adhesive trial should distinguish the product as supplied from the product after it has stood in the hopper, hose and nozzle. State whether air, moisture, temperature or component mixing changes the material. A short run that never pauses may miss skinning, stiffening, string formation or a blocked cut-off path.
Is filling two separate components the same as mixing and dispensing them?
No. Filling unmixed components into separate packs is a different duty from proportioning, mixing and dispensing a reactive blend. The second requires a defined ratio-control method and management of the mixed-material working time. Do not treat a two-head filler as evidence of two-component metering capability.
Ask for an accessible product-recovery and cleaning route before a reactive material can enter inaccessible cavities. Define how a pause is handled, which material is retained or discarded and who authorises restart. These decisions depend on the actual chemistry and the manufacturer’s product information, not a generic setting.
For pigment-rich industrial materials, compare the paint and coatings selection guide. The product-feed systems guide addresses pressure and supply stability. Send the handling conditions and intended pack so the trial can challenge the real limitations.
