How Does a Bottle Capping Machine Work?

With the packaging industry being worth billions of dollars, there is little room for error. The importance of the packaging industry is great, especially concerning things such as food and beverages, considering the safety standards that are required. The most important part of the whole operation is the capping machine. The capping machine is designed to properly seal containers to protect the components from potential contamination. If you are working in the packaging industry and are looking to inform yourself about capping machines, you are in the right place. We will go over the working principles of different capping machines and what they are used for. So, if you are interested in this topic, we recommend that you stay and read the article. Now, without any further ado, let’s dive right in.

Capping Machines

We will go over the 7 most commonly used cap machines in the packaging industry today. Each one out of these 7 machines has its own specific function and is designed specifically for that. That being said, here they are:

Tin Capping Machines

As the name itself implies, a tin capping machine is used to attach caps as well as lids on different packaging tins. These machines are most commonly used in the food industry when there is a need to seal food products. Due to the properties of the products that are being sealed, it has to be perfectly precise to avoid any possible contamination. Tin capping machines operate like any other capping machines where the tin lids are transported by conveyor belts through the different stages.

Can Capping Machines

This type of capping machine works by attaching caps on different containers such as bottle capping. Can capping machines are manufactured with several different components which all work independently from one another. This way you have an assembly line where the whole operation is working from start to finish with no problems. The components that make up can capping machines are a lid feeder which feeds the caps into the production line, a press-on head which tightens the caps onto different containers, a rotary clincher which is a screw capper that tightens lids on containers, and lastly conveyor belts which are moving everything from start to the finish of the production line.

Jar Capping Machines

This is yet another capping machine that is mainly used in the food industry. Like other machines, it is required to meet a certain sanitization level. These machines are quite flexible as they can work with both plastic caps as well as metal ones. The torque has been designed to handle the process of capping different containers with various caps. Jar capping machines are usually either screw capping machines or snap capping machines.

Screw Capping Machines 

Most commonly used for containers which utilize any form of a screw cap, a screw capping machine is being used almost everywhere. They are capable of screwing many different caps and lids such as pump sprayers, sports caps, trigger sprayers, simple flat lids, and flip-top caps. These machines will most definitely increase your overall productivity and make the production line faster and more precise.

Benchtop Capping Machines

In the case of a benchtop capping machine, the working principle, as well as the design, is basically the same as the manual capping machine. However, there is a difference between them. Mainly, a benchtop capping machine differs in that it is automated in the majority of operations it does with torque reliability also being higher. Additionally, the benchtop capping machine uses air cylinders which are activated by a footswitch that presses the cap down. This is one of the best and safest ways to apply a lid to a container with minimal labor.

Snap Capper Machines

When it comes to the working principle of snap capper machines, they are quite similar to screw capping machines. The only difference between these two machines is that snap cappers simply snap the lid or a cap onto the container. This machine can work with different containers such as bottles, tins, cans, and jars without any issues.

Bottle Capping Machines

A bottle capping machine is designed to put different types of caps on various bottles. They have large storage where the caps are held and funneled to where the bottle is being capped as necessary. As you can probably guess, the industry that mainly uses these machines is the beverage industry. As with other machines that we mentioned, bottle capping machines also need to meet a certain level of sanitary requirements as they are also dealing with products that are shipped to a wide range of customers. The capping process needs to be perfectly done, especially if the bottle capping process is done with carbonated drinks. Even a small error can ruin the product completely.
