Automatic Inline Piston Filling Machine
Product Overview
The Automatic Inline Piston Filling Machine is engineered for accurate, efficient, and repeatable volumetric filling of liquid, semi-liquid, and viscous products. Using a precision piston dosing system, the machine draws a measured volume of product into each cylinder and dispenses it smoothly into the container.
Its inline configuration allows bottles to enter, position, fill, and discharge in a continuous production sequence. The system is suitable for sauces, edible oils, syrups, creams, gels, detergents, lubricants, pastes, and other products that require controlled and consistent dosing.
Available with multiple filling heads, the machine can be configured around different container sizes, filling volumes, product characteristics, and production capacities. It can operate independently or integrate with bottle feeding, capping, labeling, coding, inspection, and end-of-line packaging equipment.
Performance Features
Precision Volumetric Dosing
The piston mechanism dispenses a measured product volume during every filling cycle, helping maintain consistent output and reduce unnecessary overfilling.
Excellent Viscosity Handling
The positive-displacement filling principle makes the machine suitable for products ranging from free-flowing liquids to thick creams, sauces, gels, and pastes.
Adjustable Filling Parameters
Filling volume, piston speed, nozzle movement, and dispensing sequence can be adjusted according to the product and container requirements.
Multi-Head Configuration
The machine can be equipped with multiple filling nozzles to increase production capacity while maintaining synchronized operation.
Anti-Drip Filling Nozzles
Specially designed shut-off nozzles help reduce dripping, stringing, splashing, and contamination around the bottle opening.
Bottom-Up Filling Option
The nozzles can descend into the containers and rise gradually during filling, helping control foaming and improve filling stability.
Stable Bottle Positioning
Adjustable guide rails, bottle sensors, and positioning devices keep containers correctly aligned beneath the filling nozzles.
Flexible Line Integration
The inline structure connects easily with bottle unscramblers, capping machines, labelers, conveyors, and inspection systems.
Easy Cleaning and Maintenance
Product-contact components can be designed for convenient disassembly, cleaning, changeover, and routine maintenance.
Custom-Built Filling Solution
The piston size, valve structure, nozzle type, hopper, feeding method, filling range, and conveyor dimensions can be selected for the actual product.

Frequently Asked Questions
1. What is an inline piston filling machine?
It is an automatic volumetric filling system that uses pistons to measure and dispense products while containers move through a straight conveyor line.
2. What products can the machine fill?
It can fill oils, sauces, syrups, creams, gels, detergents, lubricants, pastes, and many other liquid or viscous products.
3. Is it suitable for high-viscosity materials?
Yes. The positive-displacement piston system is particularly effective for products that do not flow easily through gravity-based filling equipment.
4. Can it fill products containing particles?
Certain products containing soft or suspended particles can be handled with larger product passages, suitable valves, and customized nozzles.
5. How is the filling volume controlled?
The filling volume is determined by the piston displacement and can be adjusted through the piston stroke or control system, depending on the machine configuration.
6. How many filling heads can be installed?
The machine can be configured with different numbers of filling heads according to the required output, container spacing, and filling volume.
7. Can it reduce dripping after filling?
Yes. Shut-off nozzles, rotary valves, and optional suction-back functions help minimize dripping and product stringing.
8. Can it fill foamy products?
Yes. Adjustable filling speed and bottom-up nozzle movement can help control foam during the filling process.
9. Can it handle different bottle sizes?
Yes. The guide rails, nozzle height, filling position, bottle sensors, and conveyor settings can be adjusted for different containers.
10. Can the machine be integrated into a complete line?
Yes. It can be connected with bottle feeding, capping, sealing, labeling, coding, inspection, conveying, and collection equipment.
