What products can paste fillers handle?
Paste fillers can be specified for many viscous products, including sauces, honey, jam, creams, gels, lotions, adhesives, sealants, greases and similar products, subject to product review.
Do I need a semi-automatic or automatic paste filler?
Semi-automatic machines suit lower-volume or flexible batches. Automatic machines suit higher throughput, reduced manual handling and integrated lines.
What is the difference between a paste filler and a piston filler?
A paste filler describes the application. A piston filler describes one common method used to dose viscous products by volume.
How do I reduce dripping when filling paste?
Use the right nozzle, product feed, filling speed and cut-off arrangement. Product temperature and viscosity also affect tailing.
Can paste fillers handle hot products?
Some applications may require heated or jacketed hoppers or product paths, but suitability depends on product temperature, container and machine configuration.
Can paste fillers handle products with particles?
Some systems can handle certain particles, but particle size, suspension, valve design and nozzle diameter must be checked.
Can a paste filler work with screw caps, pumps or trigger closures?
Yes, but capping should be planned around closure type, cap feeding, torque, bottle stability and line speed.
What details are needed for a quotation?
Product, fill volume, container, closure, target output, viscosity notes, filling temperature, cleaning needs, utilities and site constraints.
Are paste fillers suitable for food and cosmetics?
Many paste filling systems are used for food and cosmetic products, but material selection, cleanability and production standards must be reviewed.
Can the filler be installed as part of a complete line?
Yes. Paste filling can be integrated with conveyors, capping, labelling, coding, accumulation and support equipment.
Have a paste filling question not covered here?
Send the product, pack and output details so the application can be reviewed properly.
Engineering answers
Questions that need product evidence rather than a catalogue answer.
The questions below help turn a general paste-filler enquiry into a testable specification. Final suitability depends on the buyer’s product, pack and production conditions.
What viscosity limit can a paste filler handle?
There is no single reliable site-wide limit. Pumpability, temperature, particles, elasticity, hopper feed, pressure and nozzle passage all affect the result. Lancing should review a sample or representative data.
What particle size can pass through a paste filler?
The largest particle must fit through the narrowest valve, pump clearance, connector and nozzle. Shape and concentration also matter, so a product trial is preferable to a generic figure.
How should an accuracy claim be written?
State the product, dose, product temperature, sample count, speed and measurement method. A percentage without those conditions is incomplete.
How should machine output be measured?
Measure good containers over an agreed timed run using the real product, pack, number of heads, indexing method and downstream process. Exclude theoretical empty-machine cycles.
What is the difference between a shut-off nozzle and suck-back?
A shut-off nozzle closes the path at or near the tip. Suck-back retracts a small quantity after the fill. The correct combination depends on product pressure and stringing.
What proves a heated or mixed hopper is needed?
Product evidence showing that temperature or suspension changes during filling. The test should also confirm that heat or mixing does not introduce air, damage particles or complicate cleaning.
What should a product sample trial include?
Representative product, production containers and closures, repeated fill checks, clean-cut-off inspection, timed output, product-condition records and a cleaning or changeover review.
When should another Lancing specialist site be used?
Use Paste Fillers for thick and viscous products. Use Liquid Fillers for broader liquid methods, Volumetric Fillers for general volumetric technology, Chemical Fillers for chemistry-led safety requirements and Automatic Filling Machines for wider automatic line ownership.
Need an answer based on your actual product?
Send the product, temperature, particles, fill range, container and target output so Lancing can compare the practical machine routes.
