How do I fill thick, chunky or hot products cleanly?
Control product temperature and supply, use a dosing path sized for viscosity and particles, and match nozzle cutoff to stringing, dripping and pack opening using real production trials.
What should I check first?
Record the machine state and the finished result before changing settings. This helps identify where control is first being lost.
- Record ten consecutive fills by weight and note the product temperature, density or batch condition.
- Confirm the product supply remains stable at minimum and maximum hopper or tank levels.
- Run the slowest, thickest or most difficult product—not only the easiest sample.
- Check container opening, stability, internal neck restriction and foaming headspace.
- Verify nozzle, seals, valves and hoses are clean, undamaged and correctly assembled.
Why is this production problem happening?
Work from the evidence and change one variable at a time. These are the most relevant causes to investigate first.
- The dosing principle is unsuitable for viscosity, particles, aeration or accuracy.
- Product conditions are changing during the run.
- Supply pressure or product level is influencing the dose.
- Nozzle and cutoff geometry are causing post-fill loss.
- The required output ignores handling, changeover or downstream constraints.
How can I correct or improve it?
Make a controlled change, repeat the same measurement and compare the result before moving to the next adjustment.
- Stabilise product temperature, mixing and supply before retuning.
- Test a representative product and pack matrix across the full fill range.
- Choose or resize the pump, piston, auger, valve and nozzle around the hardest case.
- Define a measurable fill tolerance and good-output acceptance test.
- Balance the filler with container feed, closing and downstream accumulation.
What should I send Lancing?
The most reliable recommendation is based on representative production materials and a measurable acceptance result.
- Product name and a sample or SDS where relevant
- Viscosity, temperature, particles, foaming and density
- Container drawings, photos and opening size
- Minimum and maximum fill quantity and tolerance
- Required good packs per hour and batch pattern

What should I check first for paste filler?+
Record ten consecutive fills by weight and note the product temperature, density or batch condition.
Why does this problem happen with paste filler?+
The dosing principle is unsuitable for viscosity, particles, aeration or accuracy.
How can I improve or correct the problem with paste filler?+
Stabilise product temperature, mixing and supply before retuning.
Which part of the production line does this question relate to?+
This question relates primarily to filling & dosing. It may also be affected by upstream product or pack supply and by downstream handling, so check the full production sequence rather than one machine in isolation.
What should I send when asking for a machinery recommendation?+
Send Product name and a sample or SDS where relevant; Viscosity, temperature, particles, foaming and density; Container drawings, photos and opening size; Minimum and maximum fill quantity and tolerance. Representative production samples and a measurable acceptance target are normally more useful than a catalogue description alone.
