Every product that is produced and brought to market must meet certain hygiene standards to be consumable. One of these hygiene standards is a secure and sealed cap, which is of great importance in products across all industries (from food to pharmaceuticals and chemicals). To achieve this, companies producing such items use capping machines, which are among the most important machines used by various industries. If you’re curious to learn more about how a capping machine works and its types, stay with us in this article.
How the capping machine works
Just as products in various industries come in different types, different machines are used for packaging and sealing their caps. Based on this, capping machines come in different types: manual, semi-automatic, and fully automatic, with the automatic type being the most commonly used and the best option available for purchase.
However, this type of capping machine has subcategories, which we will mention below:
- Trigger capping machine: Suitable for sealing various types of caps, especially spray, pump, and trigger caps; ideal for the cleaning, cosmetics, and hygiene industries
- Double-head capping machine: Suitable for sealing regular screw caps, flip-top caps, two-stage caps, and spray caps; ideal for various plastic, metal, and glass bottles
- Eight-head capping machine: Suitable for sealing regular screw caps, flip-top caps, two-stage caps, and trigger caps (pump and spray); ideal for various plastic, metal, and glass bottles
How the trigger capping machine works
The trigger or spray capping machine, also known as the gun-type capping machine, is specifically designed for spray and pump caps and is most commonly used in the cosmetics and hygiene industries. In the following, we will explain more about how the trigger capping machine works.
This machine, which is used for capping various metal and non-metal cans, jars, plastic and metal bottles, mineral water, syrups, and other liquids, is equipped with heads located on it. After the operator places the cap on the container, the capping process is performed using a pneumatic method or air pressure.
The trigger capping machine performs the capping process with high speed and efficiency, and is suitable not only for sealing regular bottles but also for flip-top caps, two-stage caps, and trigger caps, including pump and spray caps.
The mechanism of this machine is designed in such a way that it allows producers to seal bottles of various shapes, volumes, and sizes. This machine is highly flexible and has the capability to seal 2,000 to 5,000 bottles per hour.
How the double-head capping machine works
The double-head capping machine operates in such a way that the rotation of the machine can be adjusted for screwing the bottle cap. The capping process is performed by the operator, and then the double-head capping machine seals the cap onto the product. This machine is equipped with a servo motor mast and ball screw, allowing the operator to adjust the speed and raise or lower the heads.
These machines are available in two versions: with a conveyor belt (for automatic production lines) and without a conveyor belt (suitable for semi-automatic production lines and low capacity). The double-head capping machine can be used for various types of caps, including metal, pump, spray, flip-top, and other standard caps (with a size range of 8 to 120 millimeters).
How the eight-head capping machine works
The automatic eight-head capping machine is one of the best machines used in production and packaging lines, manufactured by Radan Machine. This machine is suitable for various plastic, metal, glass bottles, and bottles with low strength, and it has the capability to seal different types of caps, including regular screw caps, flip-top caps, two-stage caps, and trigger caps (pump and spray).
The operation and design of the eight-head capping machine are such that it allows you to start with one type of cap and later adjust the machine for other types of caps and bottles. Additionally, it is possible to connect new components, such as a cap feeder and cap sorter, to this machine.
One of the advantages of this machine is its continuous, uninterrupted capping process with a capacity of 120 caps per minute. This machine is the most suitable option for jar bottles with metal caps and can be used for caps ranging from 8 to 120 millimeters in size.

Final Words
In this article, we discussed how capping machines work and their types. In general, the operation of these machines is as follows: the operator places the cap on the container, and the machine handles the capping and sealing process. These machines are capable of sealing various types of caps made from different materials, including glass (such as pickling jars, mayonnaise containers) and metal and plastic containers (such as beverage bottles, etc.).
