Liquid filling
Gravity, pump, overflow or flowmeter dosing for free-flowing liquids such as water-thin chemicals, oils and beverages.
Filling Machines for Industrial Packaging Applications
Fill liquids, pastes, powders and granules into containers by volume or weight.
A filling machine doses a set quantity of product into each container, by volume, by weight or by level. The right type depends mainly on how your product flows: thin liquids, viscous creams, free-flowing powders and granules each need a different dosing principle.
Types and configurations
Common approaches in this category. The right one depends on your product, pack and output.
Powder auger filling
A rotating auger meters fine, non-free-flowing powders into bottles, jars or pouches.
Piston filling
A piston draws and pushes a set volume. Common for viscous liquids, creams, gels and products with particles.
Volumetric filling
Cup or chamber filling for free-flowing granules and small particles where weight variation is acceptable.
Granule weighing
Linear or multihead weighers dose by weight for granules, snacks and irregular products.
Tube filling
Fills creams and pastes into plastic, laminate or aluminium tubes, then seals or crimps the tail.
How to choose
| Selection factor | Why it matters |
|---|---|
| Fill accuracy | Sets give-away and compliance with declared quantity. Ask how accuracy is measured and at what fill size. |
| Product contact material | SS304, SS316L, seals and hoses must suit the product and cleaning chemicals. |
| Cleaning method | Manual strip-down, CIP or quick-release parts change downtime between batches. |
| Changeover | Count how many container sizes and products you run, and how often you switch. |
| Output | Number of heads, fill time and indexing speed set the realistic packs per minute. |
Where it fits in a packaging line
A typical sequence. Your actual line depends on product and pack.
- Container feeding
- Filling
- Capping or sealing
- Labeling
- Coding and inspection
- Secondary packing
Technical specifications such as output, accuracy and dimensions are configuration dependent. They are confirmed against the supplier datasheet for each enquiry.
Frequently asked questions
Which filling machine is suitable for viscous products?
Piston fillers and servo-driven positive displacement pumps are the usual starting point for creams, gels, honey and sauces, because they push a fixed volume regardless of how slowly the product flows. Very thick or particle-heavy products may also need a hopper agitator, heated hopper or larger valves. A sample trial is the best way to confirm.
Should I fill by volume or by weight?
Volumetric filling is simpler and faster for consistent liquids. Weighing suits products whose density changes, high-value products and bulk containers where regulations or cost make accuracy critical.
Can one filler handle several products?
Often yes, with change parts and the right nozzle, provided the products are compatible with the contact materials and cleaning method. Confirm each product with the supplier before you buy.
Quality & reliability
How requirements are checked at each stage. Testing and documentation follow the scope agreed for each project.
Requirements review
Product samples, pack specifications, output and site conditions are reviewed and written down before any recommendation.
Supplier evaluation
Suppliers are compared on application fit, build, documentation and support, and you know who supplies each machine.
Technical specifications
Each machine is specified for contact materials, tolerances, utilities, speeds and changeovers, so quotes are comparable.
Testing arrangements
Trials with your product and factory acceptance tests are arranged with the OEM where the project scope includes them.
Documentation
Agreed scope, drawings, manuals and spare parts lists are collected for handover, as provided by the equipment supplier.
