Types of capping machines
With tons of new products on the market every day, bottle capping machines have a huge role to play. Depending on the product, different types of closures are designed for different purposes.
The intended purpose for the containers and several other factors will often determine the most appropriate bottle cap for your project.
Working principle of capping machine
With the different types of cappers available today, it is easy to envision the different principles of operation. However, the principle of operation of each machine depends on the intended use and the design of the system.
Your job will just be to change a few parts and turn a few knobs to achieve the desired result for automatic machines. The complexity of changing systems mainly depends on the containers and caps you use.
The hooded chute carries the closure and positions it where the containers can be closed seamlessly. However, the exact process may differ depending on the machine models you choose.
Different types of bottle and container capping machines
1. In-line capping machine
This tends to be the most popular automatic capping machine due to its versatility and ability to work on different containers and closures. The in-line capper can process approximately 200 capsules per minute depending on capsule configurations, intended use and requirements.
The machine has a torque control system that uses an air-loaded clutch to tighten and loosen. Therefore, the system can achieve uniformity over multiple containers.
2. Mandrel Capping Machine
Mandrel cap sealing machine designs work with the type of screw caps. Rather than using discs, mandrel cappers rely on a capping head, also known as a mandrel. Sometimes the capping head works well with a rubber insert that lowers the stopper and forces torque to seal the container.
Ideally, mandrel cappers can be automatic or semi-automatic systems. And compared to other screw cap machines, mandrel cappers are quite popular as semi-automatic options, and they come in different designs.
The rotating mandrel heads on mandrel cappers can secure a wide range of closures for various bottles and containers.
3. Automatic capping machine
Although snap caps are not as common as screw caps, they are still used for a variety of applications. These caps seal the bottles by simply snapping on the closure.
Capping machines can be automatic or semi-automatic systems. They are based on a snap-on belt or other pistons that exert pressure to engage the cap and seal the bottle. In addition, the pressure capping machine can be combined with spindle wheels to make the machine versatile enough to handle both snap-on and screw-on caps. Versatility is desirable for companies that often work with different packaging designs, such as most contract packers.
In most cases, pressure cappers are specialized systems widely used in NEPCO applications. And unlike other capping options, the pressure capper has fewer moving parts; therefore, it tends to be cheaper.
4. Spindle Capping Machine
Spindle cap machine systems operate through multiple sets of spindles or spinning discs that move caps and bottles. The spinning discs rotate the caps as they travel along the web and eventually position themselves in the right place.
Semi-automatic spindle cappers require an operator to manually place the caps on the containers before moving to the spindle for closure. But the automatic design does all the work for you. The speed depends on the vibrator which feeds the caps to the chute.
Spindle cappers can have multiple applications that do not require major machine modifications. As such, you can use it with round lugs or screw caps of different sizes since the axes are easily adjustable.
5. Dangerous capping machines
Hazardous products such as solvents, flammables and combustible materials require specialized closure due to the risks involved. The plugging systems used for these applications are often explosion proof, and the design features safe electrical enclosures to isolate and isolate electrical systems that could start a fire.
And although the machines work like most capping systems, the main difference is in the design of the safety. In the event of a spark in the safety enclosure, the explosion-proof design prevents catastrophic explosions.
Different products come in different packaging depending on the nature of the product. And while cap tightening machines serve the same purpose, applications can vary. When choosing the right design, it is best to consider the type of products and the versatility of the cap tightening machine.
