When should I move from semi-automatic to automatic filling?

Quick answer

Move when sustained good output, labour, giveaway, repetitive handling or growth justify conveyor-fed operation, and size the change around the whole line rather than filler speed alone.

Filling & dosing in a production environment
01

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.
02

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.
03

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.
Prepare your application

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

More quick answers about this problem

What should I check first for automatic filler?+

Record ten consecutive fills by weight and note the product temperature, density or batch condition.

Why does this problem happen with automatic filler?+

The dosing principle is unsuitable for viscosity, particles, aeration or accuracy.

How can I improve or correct the problem with automatic 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.
