Production risks

Four issues to resolve before machine selection

These factors commonly change the dosing method, nozzle, product feed or line layout.

Product feed

Heavy products may need ram, pump, heated hopper or controlled transfer rather than gravity feed.

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.

Project checklist

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.
