Capping systems are useful for the high-speed production of a variety of bottles and containers. Just like label machines, capping machines play a major role in a packaging line, but there are many different options to choose from. Here&#;s what you need to know.
Capping machines can be semi-automatic or fully automatic and they&#;re designed to handle many different cap and bottle styles. For instance, straight line or inline capping machines are great for a wide range of screw caps, like for water bottles and condiment bottles. Meanwhile, chuck cappers are ideal for caps and closures that are more difficult to handle and require cap placing that is straight down on top of the container for best performance.
Other types of capping machines can easily process threaded caps, screw caps, and snap caps, among others. Thanks to automatic capping capabilities, these machines make quick work of everything from beer bottles to specialty products, like caps for spray bottles and cleaning products.
You may have watched automatic capping machines in action before, but they often work so fast that you can&#;t see exactly how they function.
In reality, the internal operations vary from one type to the next. For instance, a rotary capper will need to use a different application method than a straight line capper. However, the functionality of any bottle capping machine comes down to a two-phase process: Cap placement and cap sealing.
Fully-automatic machines will place caps onto containers using either a pick-off method or a pick and place method. The pick-off method uses a highly precise chute to dispense caps onto bottles, which are quickly passing under the chute to &#;pick off&#; the caps as they come down. This system is common, especially inline or straight line capping machines and with some rotary cappers running skirted and aluminum caps.
The pick and place method is more self-explanatory and involves a robotic or robotic-like arm presenting a cap for the cap chuck to grab and place onto the container while tightening. This method is more versatile, but requires greater levels of automation and tooling for a range of cap sizes and types.
Once the cap is placed on the container, the next step is to seal it. The mechanism used to seal the cap depends on the machine and bottle/cap design. For instance, skirted caps (like those used on beer bottles) are pushed down while threaded caps need to be rotated onto the bottleneck while the right amount of downward force is being applied.
Functionally, there&#;s generally only one step that differentiates semi-automatic from fully-automatic, and that tends to be the need for a human to deliver the cap to the bottle. Still, the level of automation varies depending on the needs of the operation.
A semi-automatic chuck capper could be a tabletop version where a person is placing the bottle, then the cap, and letting the machine seal the cap down before repeating the process. Alternatively, a semi-automatic chuck capper could also be set up with a conveyor belt, which brings bottles under the machine automatically so that a human can place the cap before the machine seals it.
Semi-automatic capping machines are ideal for smaller operations and for specialized production runs. Meanwhile, fully-automatic capping machines are best suited for large operations, especially production runs that use the same actions all the way through. Ultimately, one is not necessarily better than semi-automation. The best solution depends on the needs of the operation.
Oftentimes, an operation requires a few different pieces of equipment in order to achieve the level of automation you&#;re seeking. As such, IFS offers capping machines in the following categories to help you create a complete solution.
For a semi-automated production line, feeders and sorters may not be necessary if a human is grabbing and placing caps manually. However, feeders and sorters are an important part of a fully automated production line because they prepare the caps to enter into the chute or transfer system so they can be placed onto containers.
Without sorters, caps would not always end up properly oriented, which would make it difficult to place them on the containers. Another role a sorter can play is using adjustments or change parts on the sorter bowl, which allows a capping machine to accommodate different caps.
IFS offers a variety of feeders and sorters, including vibratory sorters, centrifugal sorters, and bulk elevator sorters and feeders. The solution you choose will be based on speed and the types of caps/bottles you&#;re working with.

For a semi-automatic production line, IFS offers two benchtop models: A snap capper/plugger and a chuck style screw capper. Either machine can be mounted to a conveyor belt or slide tray and operation is made simple thanks to a footswitch. These semi-automatic cappers are able to process one container at a time.
The snap capper can be used for various caps, plugs, corks, and inserts that are placed by the operator. Meanwhile, the plugger can be specifically tooled for the plug or cork you&#;re working with, allowing the top to be held in a precise location using a vacuum. A V-block is also provided with the plugger to help the operator locate and hold the container underneath the machine.
For a fully automated solution, IFS offers seven capping machines, some with additional variations. The main models include a inline screw capper, crowner, crimp capper, inline snap capper, vertical plugger, vertical placer, and chuck capper.
If you need a vertical placer, you can choose between a single head, dual head, and starwheel design. The chuck capper also comes in multiple designs, with single head, pick and place, and starwheel variations.
To complete the capping production line, IFS offers a number of automatic cap tighteners, and similarities can make it hard to choose, which is why reading through the machine specs and asking the IFS team is very helpful in finding the right solution.
For instance, the single head inline electric chuck and dual head inline electric chuck are practically the same machine, except the latter offers a much higher throughput rate. IFS also offers an inline air chuck, starwheel air chuck, and automatic inline tightener.
With over 700 different types of packaging machinery, including a wide range of capping machines, IFS offers a solution for almost any size bottle/cap with a variety of sealing methods in both the automatic and semi-automatic categories.

When your business packages liquid goods, applying a cap or lid to each container securely is an essential part of the process. If you&#;re not currently shipping out a lot of product, or if you don&#;t have a complete packaging line up and running quite yet, you may not have implemented having a capping machine into the line yet. If you&#;re still capping your containers manually, you could be wasting a lot of time making sure that each cap is tightened or snapped securely into place. Instead, consider automating the process by integrating a capping machine into your line.
Capping machines not only speed up the process of finishing packaging of your product, but they also ensure that each cap is sanitary and that the product does not get contaminated by handling. Additionally, they allow you to save yourself from the repetitive motions of placing and tightening caps to each container yourself. There are a number of different capping machines that can help you package more product in less time&#;and not just the machines that place the caps on, either.
Capping machines can not only save time, but they can streamline the process of placing caps on containers and getting products ready for shipping. For example, instead of having to manually sort caps or manually place and tighten caps, you can let a machine do all the work for a uniform, consistent result. If your containers require plugs and not proper caps, there are also machines that can take care of that job, such as automatic vertical wheel pluggers. Save time and produce more consistent packaging with automated machinery. Add in a piece at a time, or purchase an entire system at once&#;whatever your budget allows.
Among capping machinery, there are a few different classes &#; the actual capping machines, cap sorters and cap elevators. Cap sorters work with the caps to orient them correctly before sending them along the line to the capping machines for placement. Cap elevators are part of a cap feeding system, and they are used to increase the efficiency of automatic capping machines as well as container unscrambling as the caps are pulled from a hopper and then transported to the next stop in the line. As for the actual capping machines, those include:

Like most packaging machinery, capping machines are used in a variety of different industries. Just a few of these industries are:
