Automatic Volumetric Bottle Filling Machine Manufacturer

Precision Dosing for Consistent Liquid Packaging

The Standard for Accuracy and Efficiency in Liquid Filling

A key to the modern liquid packaging technology is the Automatic Volumetric Bottle Filling Machine, which is required in industries where fill accuracy is critical to the consistency of products and cost control, including pharmaceuticals, cosmetics, edible oils, and specialty chemicals. This equipment fills each container with a specified and defined amount of liquid, unlike level-based or time-based fillers, which leave the amount of liquid unused to waste, and also guarantees a high degree of regulatory adherence.

Nextgen Packaging Solution is a specialist in how to make automatic volumetric bottle filling machines, which are designed to be either rotary or linear, with high-speed automation and a sophisticated dosing technology built in. Our machines have the capability of dealing with very slim solvents to thick creams.

Core Technology: Positive Displacement for Precision

1. Positive Displacement Pumps (Piston or Gear)

The Positive Displacement (PD) Pump is the center of the volumetric system, in which, in most cases, the piston is servo-driven or the high precision gear pump is used. The pump pulls a certain amount of product, which is measured into a chamber, and releases the same amount of that product to the bottle.

Piston Fillers: Best suited to paste products that are thick and viscous. The volume is set by the stroke length of the piston, which is controlled mechanically or electronically.
Gear/Rotary Pump Fillers: These are very suitable for medium viscosity liquids and when operating at high speed, and the amounts to be filled are calculated with the number of revolutions of the gears.

2. Servo Control and No-Drip Nozzles

A dedicated servo motor usually controls each filling head and directly regulates the pace of the pump stroke and the cut-off at any moment. This control has several speed levels in one fill (e.g., fast start fill, slow last drop) and a drip-free and clean cut-off on reaching the required volume.

3. Synchronization and Product Handling

A timing screw and star-wheel mechanism of the machine controls the movement of bottles so that a container is correctly positioned under a filling nozzle prior to the process starting. Such high-speed synchronization is the key factor to ensure the high throughput without spillage.
