A Guide to Capping Machines

Posted by . Posted on: at .

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

When it comes to diversity, there is certainly a capping machine that will perfectly suit your needs. There are 3 different main divisions, automation degree, a working principle, and application.

Automation Degree

Automatic Capping Machines

A fully automatic capping machine is generally the most popular one. It is used for a lot of different capping methods and products. An automatic capping machine can be used on many different containers, for example, tins, jars, bottles and a lot more. In addition to that, automatic capping machines are extremely fast. They can handle more than 200 caps each minute. This way, you can greatly shorten the production time. Furthermore, you can increase the production speed, even more, depending on the upgrades and how you configure the machine.

Semi-automatic Capping Machines

As the name states, this capping machine is semi-automatic. This means that it combines both manual and automatic parts. A semi-automatic capping machine is versatile as well as very easy to use. Compared to manual capping machines, semi-automatic ones can produce 20 containers every minute. These capping machines are powered by compressed air. Additionally, semi-automatic machines support a variety of different caps making production easier. Usually, when it comes to businesses, semi-automatic capping machines are best suited for small and medium workloads.

Manual Capping Machines

Even though they are not automated, these machines are versatile and simple to use. Manual capping machines do not need electricity to function. They are great for smaller businesses that do not have a large workload and do not produce that many products. Additionally, they can be used in certain situations where automatic or semi-automatic machines cannot. For example, they can be used in some explosive atmospheres. By using a manual capping machine, the cost of production will come cheaper. Being completely pneumatic, these machines are very easy to use.

Working Principle

Screw Spindle Capping Machines

Screw Spindle Capping Machines can cap numerous bottles in a row because of their cap delivery system. As they move through the machine, they are correctly placed and moved to the bottles. On the other hand, caps that happen to be misaligned will not reach the bottles. They fall into a bowl or an elevator hopper. This way the whole bottle capping process is more reliable and will ensure the quality of the product. Finally, caps get to where they need to be and they are held by a set of fingers. These fingers hold the cap in place before it is placed on a bottle.

Screw Chuck Capping Machines

Same as the screw spindle capping machine, screw chuck capping machines work by delivering caps to containers. These machines have star wheels that place the bottles below the capping head which makes the whole process very fast. The capping machine can detect if the bottle is placed correctly before it screws on the cap.

Roll On Pilfer Proof Capping Machines

Roll On Pilfer Proof capping machines, or ROPP for short, work by creating a thread in the caps upon sealing the container. In most cases, the caps that these machines use are unthreaded aluminium blanks which are placed on the desired container. These machines do not use torque and require a sturdier container that can endure the pressure from the sealing.

Press Push-On Bottle Capping Machines

Press Push-On bottle capping machines can operate at very high speeds of up to 105 caps each minute. They secure press-on and push-on caps on different containers. Usually, these machines are built from anodized aluminium and stainless steel because of the durability of these materials. Because of that, these machines are very resistant to corrosion and will last for a long time.

Different Applications

Bottle Capping Machines

A bottle capping machine is mainly used in the beverage industry for proper bottle sealing so they remain safe for consumption.

Jar Capping Machines

A jar capping machine is a necessity in businesses that deal with jar containers. They are specifically designed to seal jars which ensures the quality of the product while also being safe for the consumer.

Tin Capping Machine

These machines are extremely versatile and are used in many different industries. Where any leakage is unacceptable, tin capping machines are used. They will ensure that every container is sealed perfectly and that it can securely be transported and later consumed.
