A Guide to Capping Machines

Posted by . Posted on: at .

Capping machines are an integral part of the production industry. It ensures a quality product that is going to be safe for consumers to use. The entire process depends on the capping tools. When it is properly sealed, the interior is isolated and protected from contamination. Here we will talk about everything you need to know about capping tools. If you are planning to start a packaging company, or if you already have one, this article is for you.

When it comes to versatility, there is sure to be a capping machine that will perfectly suit your needs. There are 3 main different categories, automation step, working principle, and application.

Step automation

Automatic capping machines

Fully automatic capping machine usually the most popular. It is used for many different capping methods and products. An automatic capping machine can be used on many different containers, for example, tins, jars, bottles and many more. In addition, automatic capping machines are very fast. They can handle more than 200 caps per minute. In this way, you can significantly shorten the production time. In addition, you can increase the output speed, even more, depending on the updates and how you configure the device.

Semi-automatic capping machines

As the name suggests, this capping machine is semi-automatic. This means that it combines both manual and automatic parts. A semi-automatic capping machine is flexible as well as very easy to use. Compared to manual capping machines, semi-automatic ones can produce 20 devices per minute. These capping machines are powered by compressed air. In addition, semi-automatic machines support several different caps making production easier. Usually, when it comes to businesses, semi-automatic capping machines are best suited for small and medium workloads.

Hand capping tools

Although not automatic, these tools are flexible and easy to use. Manual capping machines do not require electricity to operate. They are great for smaller businesses that don’t have a large workload and don’t produce as many products. In addition, they can be used in certain situations where automatic or semi-automatic devices cannot. For example, they can be used in some explosive atmospheres. By using a manual capping machine, the cost of production becomes cheaper. Being completely pneumatic, these tools are very easy to use.

Working Principle

Screw spindle clamping devices

Spindle Screw Capping Machines can place multiple bottles in a row due to their cap delivery system. As they move through the machine, they are positioned correctly and transferred to the bottles. On the other hand, caps that happen to be mislabeled will not reach the bottles. They fall into a bowl or lifting hopper. In this way the entire bottle capping process is more reliable and ensures the quality of the product. Finally, caps get where they need to be and are held in place by a set of fingers. These fingers hold the cap in place before it is placed on a bottle.

Screw Chuck Capping Machines

Like the screw spindle capping machine, screw chuck capping machines work by delivering caps to containers. These machines have star wheels that place the bottles under the capping head which makes the whole process very fast. The capping machine detects if the bottle is placed correctly before screwing on the cap.

Pilfer Roll On Proof Capping Machines

Roll On Pilfer Proof capping machines, or ROPP for short, work by creating a thread in the caps when sealing the container. In most cases, the caps used by these machines are aluminum blanks without thread that are placed on the desired container. These tools do not use torque and require a more durable tool that can support the weight of the seal.

Press Push-On Bottle Capping Machines

Press Push-On bottle capping machines can operate at very high speeds of up to 105 caps per minute. They secure push and push caps on various vessels. Usually, these devices are constructed from anodized aluminum and stainless steel due to the durability of these materials. Because of that, these tools are very resistant to corrosion and last a long time.

Different applications

Bottle capping machines

A bottle capping machine is mainly used in the beverage industry for sealing bottles properly so that they are safe for consumption.

Jar capping tools

A jar capping machine is essential in industries that deal with jar containers. They are specially designed to seal jars which ensures the quality of the product while being safe for the consumer.

Tin cap tool

These tools are very versatile and are used in many different industries. Where no leakage is acceptable, tin capping devices are used. They will ensure that every container is perfectly sealed and can be safely transported and consumed later.
