Accurate Filling for Liquids, Pastes and Gels
Piston fillers measure each dose through the controlled movement of a piston inside a cylinder. This volumetric principle provides consistent filling for products ranging from free-flowing liquids to thick pastes and products containing small particles.
Servo Piston Fillers
Servo-driven systems provide programmable filling control, convenient volume adjustment and stable operation for automated production.
Integrated Filling Lines
Piston fillers can be integrated with bottle feeding, capping, labeling, conveyors, mixing tanks and product feeding systems.
Which Piston Filler Should You Choose?
Selection depends on product viscosity, particle size, filling volume, container opening and required output. Heating, mixing, feeding and explosion-resistant configurations can be evaluated according to the application.
| Product type | Typical applications | Suggested configuration |
|---|---|---|
| Flowable liquid | Oil, detergent, shampoo | Standard piston filler |
| Viscous paste | Cream, honey, sauce, gel | Servo or pneumatic piston |
| Product with particles | Chunky sauce, jam, relish | Large-port piston system |
| Temperature-sensitive paste | Wax, balm, heated cream | Heated hopper and nozzle |
Piston Filling Machine FAQs
What products can a piston filling machine handle?
Piston fillers are commonly used for sauces, creams, gels, honey, lotions, shampoos, detergents, oils and other liquid or paste products. The valve and cylinder configuration must be matched to the product’s viscosity and particle content.
What is the difference between pneumatic and servo piston filling?
Pneumatic models use compressed air to drive the filling cycle and are suitable for flexible batch production. Servo models provide programmable motion control and are generally preferred for automated lines requiring faster adjustment and coordinated multi-head operation.
Can piston fillers process products containing particles?
Yes, when the machine uses a suitable large-port valve, cylinder and nozzle. Particle size, concentration and product consistency should be confirmed before choosing the configuration.
Can a piston filling machine connect with a complete packaging line?
Yes. Automatic piston fillers can be connected with bottle unscramblers, capping machines, labeling machines, conveyors and product feeding systems to form an integrated packaging line.
