Guide to Capping Machines

Anyone in the packaging industry knows the importance of having quality machinery. If your business includes filling bottles with liquid, you’re aware that two essential pieces of hardware include a filling machine and a capping machine.

A dependable capper will boost your production line and maintain high efficiency across the entire business. However, selecting the correct capping machine for your needs depends on various factors. Increased speed is the usual motivator for getting an automatic capper. However, many companies use semi-automatic machines that may not significantly enhance speed but provide impeccable reliability and consistency.

For those who aren’t sure what type of capping machine to use, we’ll go over the basics in this article, so you know what to pay attention to when getting a new capping machine.

What is A Bottle Capping Machine?

Any liquid packaging line requires a quality cap machine. It ensures the bottles are correctly sealed, and the liquid inside the container isn’t going anywhere until the customer decides to open the cap. An automatic capping machine will place the lid at the right spot and tighten it on various containers. You can use them for medicine bottles, beverage bottles, and many other liquid container types.

Although there is a vast number of various types of capping, the following are the most common ones:

– Screw caps

– Press-on caps

– Crown closures

– Tear-off caps

– Cork caps

– Child-resistant closures

– Tamper-proof seals

How do you use a capping machine?

There are many forms of bottle cappers, and they come in various automation levels. The variety ranges from simple equipment to sophisticated, fully automated machines.

An essential thing in choosing suitable capping machines for your production line is to know how the devices operate. It will help you calculate the time and labor needed to seal an optimal number of containers.

If the machine is fully automatic, it will usually require an operator to keep an eye on it and supply bulk caps when needed. However, if the device is semi-automatic, it usually requires more human labor and assistance from operators. Depending on the level of automation, some capping machines may require the operator to place the cap on each container, while others may require more manual work.

It’s crucial to ask all the necessary questions before deciding what machine fits your needs.

How to Choose a Capping Machine

To choose a perfect machine and enhance your production line, you first need to know what type of a capper you need. Capping machines vary in technical specifications. Some of the most common differentiators include:

Cap Size

It’s best to carefully choose a machine that fits your requirements depending on the type of bottle or container your production line uses. Some devices cover only a specific kind of containers, while others cover a more comprehensive range of variations.

Machine Dimensions

A machine can be the most brilliant one globally, but it still won’t suit your needs if you must rent out a new place for your business. Some cappers are very large.


Heavy containers require heavier machines to handle all the product weight safely.

Torque Range

The torque range can be very different from one capping machine to another, usually depending on your closure type.

Electrical Requirements

All capping machines depend on electricity. Keep in mind that different cappers require different electricity conditions. With some toppers, you may need to ask a power company to help you set up and allocate your new machine.

Air Requirements

Cappers differentiate by the pressure they use to tighten the cap.

Cap Type

While some machines can work with different types of closures, some only use a few variations.
