How do filling machines work?
Learn how industrial filling machines measure product, control flow, position containers and coordinate a repeatable filling cycle.

Filling-machine questions and practical answers
Use this resource to move from a buyer question to the product, pack, process and acceptance evidence needed for a sound filling-machine decision. Each answer has one clear page owner and links to deeper selection guidance.
How to use the library
Start with the decision you are trying to make
The shortest useful answer is often a condition: the result depends on product behaviour, dose, pack geometry, required accepted output, cleaning and line interfaces. Follow the relevant task below, then use the linked checklist to prepare an enquiry or trial.
- 1
Define the real product and its difficult operating condition.
- 2
Identify whether quantity, level, mass, appearance or piece distribution is the controlled result.
- 3
Use representative containers and include the least stable or narrowest-opening format.
- 4
State the target accepted output with operator and linked-machine assumptions.
- 5
Record open questions in the quotation, URS and acceptance plan.
Answers are application guidance
The pages explain selection and testing principles. They do not replace a product trial, competent safety assessment or the verified specification for a particular Lancing machine.
Understand and compare the process
Inline or rotary filling machine: which layout fits the process?
Compare inline and rotary filling-machine layouts by container handling, changeover, footprint, control, output and line integration.
Read the answerWhat is the difference between level filling and volumetric filling?
Understand the difference between liquid-level filling and volumetric filling, including bottle variation, quantity control and inspection.
Read the answerMatch product and product path
How do you fill products that contain particles or pieces?
Select and test filling equipment for liquids and pastes containing pieces, fibres, seeds or suspended solids without guessing passages or performance.
Read the answerWhat are product-contact parts in a filling machine?
Identify the product-contact boundary in a filling machine and review hoses, seals, valves, nozzles, materials, drainage and cleaning access.
Read the answerWhat is bottom-up filling and when is it useful?
Understand bottom-up filling, when nozzle travel may reduce foam or splash, and which product, container and trial conditions must be proved.
Read the answerCan one filling machine handle multiple products and pack formats?
Assess whether one filler can run several products, doses and containers by reviewing product path, recipes, format parts, cleaning and trial evidence.
Read the answerSpecify and verify the project
How do you write a user requirement specification for a filling machine?
Write a filling-machine user requirement specification covering product, packs, output, accuracy, cleaning, safety, controls, FAT and SAT.
Read the answerWhat is the difference between gross-weight and net-weight filling?
Compare gross-weight and net-weight filling sequences, tare handling, container variation, weigh hoppers and acceptance evidence.

Continue into testing, performance and acceptance
These established guides provide the detailed process after the initial question has been answered.
Which dosing technology suits the application?
Compare piston, pump, peristaltic, vacuum, auger and weigh methods.
Open the guideWhat should a product and pack trial prove?
Plan samples, conditions, observations and acceptance evidence.
Open the guideHow should filling-machine output be specified?
Define sustainable accepted packs with normal line states and operator work.
Open the guideHow should fill accuracy and repeatability be tested?
Define the controlled variable, measurement system, sampling and calculation.
Open the guideWhat should FAT and SAT include?
Trace requirements into factory and installed evidence.
Open the guideHow should filling problems be investigated?
Work from the observed symptom through product feed, dosing, nozzle and pack handling.
