What Are Capping Machines And How Do They Work?

Quality packaging is crucial for businesses as it ensures product freshness and prevents leakage. Capping machine is play a important role in your packaging business.

Let’s explore more about what is capping machine, how does it work and what is its application.

What is capping machine?

A capping machine is a machine used to close various types of bottles and jars. They are widely used in many different industrial sectors, such as pharmaceuticals, cosmetics, food and beverages, etc.

The working principle of the capping machine is to tightly seal the lid on the bottle or jar by rotating it, thus maintaining the freshness, safety and quality of the contents inside.

Working principle of capping machine:

The working principle of the capping machine is simple. It completes the process of closing bottles or jars by rotating the lid. On the top of the machine, there are rotating discs that can be fixed to the bottom of bottles or jars.

When the bottle or jar is placed on the rotating disc, the machine automatically places the cap on the bottle mouth.

The rotating disc then begins to rotate, rotating the lids into the correct position until they seal tightly around the bottle or jar.

Types of capping machines:

There are many different types of capping machines, including high speed capping machine, universal capping machine, manual vacuum capping machines,

semi-automatic capping machines, and fully automatic capping machines.

Manual capping machines are usually operated manually and are suitable for small-scale production environments.

Semi-automatic capping machines are operated by a single operator but require less manual intervention.

The fully automatic capping machine can automatically complete all operations without manual intervention and is suitable for large-scale production environments.

What is the difference between automatic capping machine and double-head capping machine?

1. Definition and Principle

1）Automatic capping machine

The automatic capping machine is a device that can automatically complete the capping operation. It is mainly suitable for capping bottles or boxes with regular shapes.

It can automatically screw on or off the bottle cap. Its principle is to adjust the appropriate torque and speed by setting the capping machine so that the bottle cap can be stably screwed in or out.

2）Double-head capping machine

The double-head capping machine is a device that can cap two bottles or boxes at the same time, which can greatly improve production efficiency.

In the double-head capping machine, the two capping heads can independently adjust the torque and speed of the capping to best meet the needs of screwing on or off the bottle cap.

2. Differences and usage scenarios

1）Difference

The main differences are:

The automatic capping machine can only process one bottle or box at the same time, while the double-head capping machine can process two at the same time;

The automatic capping machine has only one capping head, while the double-head capping machine has two;

The automatic capping machine can only adjust the torque and speed of one bottle cap, while the double-head capping machine can adjust the torque and speed of two bottle caps respectively.

Products suitable for double-head capping machines are generally small in size and have relatively small caps, such as pharmaceuticals and small cosmetics.

In summary, both automatic capping machines and double-head capping machines have their own advantages and disadvantages, and the choice should be based on product needs and production efficiency.
