An automatic filling machine is a vital part of any efficient packaging line, offering fast, precise, and hygienic liquid dispensing across a wide range of industries.
Whether you’re packaging pharmaceuticals, cosmetics, food, beverages, or chemicals, an automatic bottle filling machine can significantly increase throughput, reduce waste, and ensure consistent product quality.
Universal Filling Machine Company specialises in British-built, high-quality automatic liquid filling machines, supporting businesses worldwide with reliable equipment tailored to their unique production needs.
What Is an Automatic Liquid Filling Machine?
An automatic liquid filling machine is designed to dispense measured volumes of liquid into containers without the need for manual intervention.
These machines can operate continuously in production environments, automatically managing container handling, filling, and—when integrated—capping and labelling.
These systems are part of a complete liquid filling system, which may include bottle feeding, filling, cap placement, sealing, and coding—all synchronised to maximise productivity.
Types of Automatic Filling Machines
Universal Filling Machine Company offers two main types of automatic filling systems: volumetric piston filling and vacuum filling. Each is optimised for different product characteristics and container types.
Volumetric Piston Filling Machines
Our volumetric piston filling machines are among the most versatile solutions available. These machines use pneumatically or mechanically operated pistons to draw and dispense liquid in highly controlled volumes.
Unlike flow meter-based systems, piston fillers are ideal for both low and high-viscosity products. They can handle:
-
Thin liquids like oils and sanitisers
-
Viscous products such as creams, shampoos, sauces, and gels
-
Products with particulates, like soups or fruit preparations
Available in semi-automatic and fully automatic configurations (like the Posimatic EV1000, EV2500, and EV5000), these machines support fill volumes from as low as 5ml to over 5 litres, with exceptional accuracy (typically ±0.5%).
Vacuum Filling Machines
Vacuum filling is ideal for thin, free-flowing liquids such as perfumes, toners, and light oils, particularly when filling into rigid containers like glass bottles.
It works by using a vacuum to draw liquid into each container until it reaches a consistent level.
This method is extremely clean and precise, minimising foaming and ensuring a consistent fill height—particularly important for retail presentation. Universal’s Posivac machine is a robust, hygienic solution for vacuum-based filling lines.
How Does an Automatic Filling System Operate?
An automatic filling system typically works in a continuous, synchronised process:
- Container Infeed – Empty bottles or jars are fed into the system via a conveyor.
- Indexing & Positioning – Containers are aligned and held in position under the filling nozzles.
- Filling Cycle – Product is dispensed using piston or vacuum technology, depending on the system type.
Nozzle Retraction – In piston systems, the nozzles may dive into the container and retract (bottom-up filling) to prevent splashing or foaming.
Container Discharge/Outfeed – Filled containers are released for capping, labelling, or further processing.
Advanced systems offer touch-screen HMI controls, recipe storage, tool-free changeovers, and integration with ancillary equipment such as automatic capping machines (e.g., the Posicap or Universal Belt Capper).
