Parts of Tube Filling and Sealing Machines

Tube filling and sealing machines are made up of different parts that work together to ensure effective tube filling.

Let’s look at some of the most common components:


Tube-filling machines are composed of filling nozzles that serve as a significant part of the tube-filling process. The filling nozzles are normally made of different sizes depending on the type of liquids they are intended to fill.

For example, filling nozzles can be made relatively large to fill tubes with highly viscous substances such as paste.  Similarly, the size of the nozzles of filling machines can also be made thin for tubes that are intended to hold liquids with low density.

Control Chamber/Unit

The control unit is also a significant part of the tube-filling machine. As such, this part is termed the main part of the machine since numerous working components are housed inside this unit. Similarly, it is designed to control the performance of the tube filling system as well as regulate the performance of the system.

Modern tube filling and sealing machines are made with automated control units that execute functions such as regulation and control. As such, they are made with buttons that can be used to adjust regulate and perform various functions at ago. These functions include increasing the tube filling speed among others.


The tube filling and sealing machine consists of a body that is mainly made of a metallic material. It serves as one of the significant parts of the machine in that it houses all the other components of the machine.

Additionally, the body is made from materials that have high tensile and mechanical strength since they can withstand high pressure that could otherwise cause them to break.

For example, the most preferable material used in the making of tube filling and sealing machine bodies is stainless steel. This is because they have a strong tensile and mechanical strength therefore guaranteeing the lifespan of the machines.


They are sometimes referred to as dosing pumps and are used for the displacement of substances. As such, dosing pumps are connected to dosing units to ensure that they fill the correct amount of substance to this unit.

Additionally, these pumps are normally made multi-purpose in that they have a two-way operation system. In this instance, they can be operated manually or automatically using internally enabled electric motors.

Coding Jaws

Coding jaws are equally important parts that constitute a tube filling and sealing machine. As such, they are designed to control and regulate the performance of the system depending on the demands of the manufacturers.

Safety System

The safety system in a tube filling and sealing machine serves as an important part of the system. It ensures the safety of all other parts of the system by alerting the operators whenever there is a system malfunction. As such, this prevents further damage and breakdown of parts that might compromise the quality of products.

The safety system is designed to alert the operator by ringing an alarm which serves as a warning signal. Most advanced tube filling machines are designed with the ability to conduct a self-test within themselves in case of machine malfunction and troubleshoot to mitigate the problem.


Hoppers in tube filling machines refer to funnel-like parts that significantly help in the composition of the materials into the equipment. Similarly, hoppers are made adjustable to regulate and control the displacement of filling substances from various places.

Tube Holders

Since the tube filling machine can produce up to 125 tubes per minute, empty tubes need to be held firmly into position to ensure effective filling and avoid spillovers that could otherwise result in losses.

As such, the rotating speed of tube holders is expected to be equivalent to the filling rate of discharging tubes. This ensures accurate filling of substances, avoids wastage through spillovers as well as ensures consistency.

Storage Chamber/Unit

A storage chamber in a tube-filling machine is responsible for holding substances that await to be filled in the tubes. This chamber is commonly made up of materials with high mechanical strength such as steel that cannot be easily affected by an increase in pressure of the substance.

How Tube Fillers Work

Tube filling and sealing machines may have a two-way working principle that can either be manual or automated. However, in recent times, most commonly produced tube fillers have been designed automated thereby making them simple to operate.

As such, most of the functions are machine operated aided by the monitor that is used to instruct and control various production processes such as increasing the filling speed. Furthermore, the whole process from filling empty tubes to packaging the final product is automated.

Similarly, this process is automated and it is aided by the monitor which is used for inserting production instructions. Notably, tube filling and sealing machines have different types of fillers depending on the type of substance being worked upon. For example, they include liquid, gas as well as adhesion fillers.

Furthermore, the filling technique for tube fillers includes vacuum filling technique, gravity as well as volumetric filling technique. Vacuum fillers operate with the use of a vacuum that is created to ensure that the filling substance is sucked into the tube from the hopper.

On the other hand, gravity gravity-filling technique significantly utilizes the pull of gravity. As such, the force of gravity necessitates the movement of filling substances from the hopper to the necessary part. Volumetric fillers on the other hand utilize volumetric pumps during their operation. As such, these pumps are used to dispense filling substances from the hopper to the tubes.
