A capping machine is a device for sealing containers or bottles by twisting the cap. Machines can be automatic, semi-automatic, and manual. Capping equipment can speed up production and ensure product safety.
Using a capping machine on a production line eliminates repetitive tasks and maintains product consistency. This article will help you learn more about the machine.

Working Principle of a Capping Machine
Cap screw machines use two systems to place caps on containers. A precise cap chute is fed to the cap from the sampling system, and the cap is picked up by the bottle as it passes under the chute. The system is generally compatible with a variety of lids, including skirts and aluminum lids. This is common with rotary cappers and inline cappers.
Another system is known as “pick and put”. This includes a robotic arm that lifts the container and places the lid on it. In general, these systems are more versatile as they are compatible with almost all types of closures used in different industries for different products.
When the lid is placed on the container, the capping head seals the container and the mechanism used depends on the type of seal and the characteristics of the product in question.
When using an aluminum skirt cap, the machine applies downward pressure as the rollers form a seal to fit the bottleneck. However, when using a threaded cap, the machine applies torque and downward pressure to create a tight seal.

Uses of Capping Machines
Capping bottles and containers are one of the last steps on any production line. Capping machines serve a variety of purposes and most industries rely on capping machines to cap products.
Cappers may vary for specific applications. Some models are designed for industrial, agricultural, chemical, or food industries.
Here are some industries where capping machines are used.
- Pharmaceutical Industry
- Chemical and Agricultural
- Food and Beverages
- Industrial and General Packaging
