What is filling machine? The packaging industry uses a filling machine to fill containers with various products. This machine applies to thousands of different applications.

A filler machine fills different products into containers, such as glass, plastic, or metal bottles, jars, cans, cups, bags, sachets, pouches, etc. Filling products can be solid, liquid, powder, paste, and granule.

Here’s Why You Need a Filling Machine

A filler machine can be helpful if the time it takes to fill your containers is excessive or if the cost of labor becomes a problem.

If you’re producing a couple of dozen bottles and making, filling, and labeling them by hand, you may not need filling equipment. If you’re experiencing issues with production quality, speed, fill level accuracy, or sanitation as your output increases, a filling machine may be the solution.

To handle more volume, an automatic bottle feeder or bottle unscrambler is advisable. Having at least one worker to put bottles into production lines all day is sensible financially.

Different Types of Filling Machines

🔵 Liquid Filling Machine

This machinery fills containers with liquid products. One of its most important features is that this machine dispenses just the correct quantity of liquid.

Multiple versions of these devices may do unique tasks. They are:

  • Manual Liquid Filling Machine
  • Semi-Automatic
  • Fully Automatic
  • Piston Liquid Filler
  • Inline Liquid Bottle Filler
  • Rotary Liquid Filler
🔵 Granule Filling Machine

Pack grains into sachets and packages. This machine uses many vibrating trays to transport objects to a weight container. When the weight is correct, the vessel fills the container.

This machine meets the requirements for filling granules, which call for precise quantities. Its precision makes it a popular tool in the chemical industry.

🔵 Powder Filling Machine

The spiral feeding technique of the powder filling machine allows a zero-drip filling process. They are perfect for filling free-flowing and non-free-flowing powdered and granular products.

🔵 Tube Filling and Sealing Machine

A tube filling machine fills plastic tubes with ointments, creams, toothpaste, and other materials. Tube fillers are dependable and accurate, filling tubes cleanly and quickly. Its task includes ensuring the tubes are filled according to the correct requirements.

🔵 Gel Filling Machine

The pump head is a key component of this machine. Its benefit is that it handles several chemicals easily. They fill thick liquids like gels, creams, and lotions. It can also fill pastes and water-thin drinks. Products like this come in many forms, from shampoo, creams, thick sauces, jams, paste, and even automobile wax.

🔵 Capsule Filler Machine

This capsule filling machine fills containers by counting bits, not weights. It fills medicines in the pharmaceutical sector. They effectively count soft and hard gelatin capsules, coated pills, and tablets. This filling equipment finds use in healthcare, food, agriculture, and chemical engineering as well.

Important Factors to Consider When Choosing a Filling Equipment

The best filling device for your specific requirements will be custom-made from the many options available. The most essential factors in choosing the suitable machine are:

🔵 Filling Speed

A rotating, semi-automatic, or automatic inline filler can be necessary based on daily bottle volume. Remember that a speedier filler will often cost more.

You may hand-manufacture any technique cheaply and produce several hundred bottles daily. However, faster, cleaner, and more accurate outcomes need more costs.

🔵 Container Type

Bottles, bags, pouches, sachets, cans, jars, etc. are containers. Understanding container qualities is crucial when choosing a filling machine. This will help you decide the machine’s filling process, as the bottle’s qualities must match the machine’s to perform well.

🔵 Product Material Properties

There are filling machines for liquid and powder. The machine’s filling process depends on your product’s viscosity. When dealing with liquids or pastes, use a pump-filling device. Also, a position or gravity-filler machine is suitable for particles or semi-solids.

🔵 Filling Product

Currently, no silver bullet technology can be applied to all products; the most adaptable filling machines also tend to be the most expensive.

Every filling process is different, and even though the overflow filler may be suitable for a particular application, the recommendation would change if you need to fill higher-viscosity materials. These are instances and common recommendations.

Piston Fillers

Because of its adaptability, piston fillers ruled bottling for over a century. This filler can handle liquid materials that are either water-thin or mayonnaise-thick with the proper nozzle.

Overflow Fillers

Overflow fillers are your best choice if you need to fill items with a viscosity similar to water or very light oil. Compared to most other filling techniques, these are more efficient, accurate, and affordable.

Explosion-proof Overflow Fillers

This filling process accommodates the high demand for combustible materials. This has pneumatic systems, explosion-proof motors, built-in sensors and barriers, and cement-filled electrical boxes to ensure no electrical spark is happening anywhere in the building.

Choose The Filling Machine For Your Product

Filling is generally fast and simple if the raw material is a liquid with high fluidity. Still, if the raw material is viscous, it must be heated for smooth filling or may be filled using a piston filler machine.

For diverse filling needs, use different equipment. Some are good for high-fluidity liquid, paste, and granular filling machines. Thus, choosing a filling machine takes careful analysis of your demands.

Filling Machine Principle

Filling machines work the same at normal, high, or negative pressure. Normal pressure filling machines fill from self-weight, high-pressure machines in high-pressure environments, and negative pressure machines in low-pressure environments.

Filling machines handle various raw materials. The atmospheric-pressure filling machine fills high-fluidity liquids, while the high-pressure filling machine fills mayo and ketchup. Negative pressure-filling equipment can safely fill hazardous raw materials.

Filling Machines Have Many Advantages

🔵 Efficacy Enhancement

A filling machine may be either semi-automated, which requires some human help to operate, or automatic, which can handle packing, cardboard casing, and filling in a single operation. Efficiency in productivity would result from reducing manual labor and shortening the packing process.

🔵 Automated Filler Simplifies Work

Based on your skill and experience, manually filling containers might lead to irregular amounts or product loss. Using a filling machine guarantees that each package has the appropriate quantity of the product, is of constant quality, and operates smoothly and fast.

Filling machine or packaging machine?



They are designed and created to package a range of goods with highly functional features. These machines are all available in various forms to meet different packaging requirements. They fulfill different functions. A packing machine may carry out the tasks of weighing, filling, bagging, sealing, and labeling automatically. A filler machine does not have a bag-making or bag-sealing feature. That is to say, there are different levels of automation. A filling device requires additional hands to operate.

Automatic Filling Machine Price

The pricing of an automated filling equipment is the first question you may ask. Automatic filling machines come in multiple types and cost differently.

First, each customer’s need is different, hence their prices vary. Using a self-flow filling nozzle to fill pure liquids makes such filling machines simple. While filling, thick materials like cream or mayo need a piston pump to operate smoothly. Knowing how many piston pumps and filling nozzles you need is essential as the price rises proportionately with the number of piston pumps.

Also, a weighing filling device, which costs more than a self-flow filler, weighs granular or powder material after filling to check accuracy.

Secondly, costs differ if your automatic filling equipment needs an automatic capping machine. A complete filling production line, a monoblock automatic filler, and a filling production line cost twice as much for customers wanting an automated labeling machine.


Filling machines serve an essential purpose today. It’s a model of efficient manufacturing at its finest. A production line that fills products is not a simple investment, however.

For your efforts to be successful, choose a suitable filler machine. For over 15 years, MAKWELL has been a leader in the filling machinery industry. Please get in touch with us right away if your company needs a specialized filling solution.
