What does a filling machine do?
Every filling machine performs three jobs: it presents the container under a filling nozzle or chute, it measures the dose, and it transfers the dose into the container without spills, drips or dust. Automatic machines then pass the container on to capping, sealing or labelling.
Types of filling machines by product
| Product | Dosing method | Example |
|---|---|---|
| Thin liquids | Peristaltic or piston pump | Y2 two-nozzle small bottle filling & capping machine |
| Lotions, syrups, shampoo | Piston or pump | Liquid & lotion filling and capping machine (50–1000 ml) |
| Honey, sauces, peanut butter | Piston or rotor pump | J8B peanut butter & sauce filling and capping machine |
| Wax, gel, solid perfume | Heated piston filler | J4B heated filling machine for gel, wax and solid perfume |
| Powders | Auger (screw) | F2 powder & granule jar filling and capping machine |
| Granules, nuts, grains | Weighing heads or measuring cups | KGZ10 ten-head weighing bottle filler for granules |
| Tablets, capsules, gummies | Electronic counting | DSL8 tablet & gummy counting bottle line |
| Aerosol products | Liquid fill, valve crimp, gas fill | Aerosol can filling, crimping & gassing machine |
| Yogurt and sauce cups | Piston fill + foil seal | Rotary cup filling & sealing machine |
Volumetric vs weight vs level filling
- Volumetric — the machine displaces a set volume each cycle (piston, auger turns, cup). Simple and fast; accuracy depends on stable density.
- Weight (net weight) — load cells weigh each dose. Best for expensive products or variable density.
- Level (overflow) — fills every clear bottle to the same visual height. Used for clear bottles on shelf; volume varies with bottle tolerance.

Automatic, semi-automatic and manual fillers
Manual and tabletop fillers dose when the operator presses a pedal. Semi-automatic machines automate the dosing but the operator places containers. Fully automatic filling machines index containers on a conveyor and usually include capping. See semi-automatic vs automatic filling machines.
Where industrial filling machines are used
Food and beverage (juice, sauces, honey, oil, spices), cosmetics and personal care (perfume, serum, lotion, lip gloss), pharmaceuticals and supplements (oral liquids, eye drops, tablets, gummies), chemicals (paint, detergents, lubricants) and household products (air fresheners, aerosols).

Questions and answers
What are the main types of filling machines?
Liquid fillers (piston, peristaltic, pump, gravity, overflow), paste fillers, powder auger fillers, granule weighing or cup fillers, counting machines, aerosol fillers and cup filling-and-sealing machines.
What is the difference between a filling machine and a packing machine?
A filling machine doses product into a rigid container that already exists. A packing machine such as a VFFS bagger usually forms the bag and fills it in one machine.
How accurate is an automatic filling machine?
Our catalogue fillers list about ±1% or ≥99% accuracy, depending on product and container.
Can a filling machine also cap bottles?
Yes. Many machines are monoblocks that fill and cap on one frame, which saves space and avoids extra transfers.
