Global Reach: Over 12,500 Machines Installed In 60+ Countries And Still Counting...


When you work in a business that uses liquid-filling machinery to package products, you know that having the process be as automated as possible is the goal. For instance, having volumetric fillers help fill liquids into containers at an even, consistent fill level, while cooling conveyers help molten products cool off more quickly than traditional conveyor belts. One of the last steps in automating the process for a lot of businesses is the capping or sealing of the product. Many businesses choose to do at least part of this process manually, from filling the hopper of caps to the actual capping of the containers. Not only is this a tedious process, it takes a lot of time that can be spent focusing on other aspects of your business. Thankfully, several different machines can help mitigate the difficulties that come along with manual capping.

Cap Elevators

Cap elevators allow caps to be stored until they’re ready to be used. Rather than keeping the caps in a box somewhere, this automatic elevator hopper is designed to supply caps to an automatic capping machine down the line. The machine is activated when the hopper to a capping machine is getting low. It is designed to feed a wide range of different-sized caps, from 10mm to 110mm, so is a versatile choice when you want to automate the first part of the capping process—the actual act of finding the caps.

Cap Sorters

Cap sorters are a helpful machine that helps position caps so they are facing the correct direction when the capping machine picks them up to be used. Cap sorters are available in an elevator setup, which helps bring up a supply of caps to the capping machine, or a vibratory setup, which works by shaking the surface that the caps are on until the cap switches to being positioned correctly. These machines ensure that the capping machines can do their job efficiently once the caps are ready to be placed.

Capping Machines

Finally, the capping machines themselves are what place the caps onto each container. For these types of machines, there are four options – spindle cappers, chuck cappers, snap cappers and wheel pluggers. Spindle cappers spin the lids onto the product as the container sits stationary underneath a station. Chuck cappers also spin caps onto containers, but this machine is designed to keep the products moving at a consistent pace, so the lid is placed on the container and then the container runs through the machine, which has lid tighteners along the top. Snap cappers snap the caps onto the container tightly, and vertical wheel pluggers are used for containers that require plugs rather than lids or caps.

Saving time is easy when you use capping machines from HMPL. Don’t stress yourself out by continuing to manually cap your products. Instead, use these machines to automate the process, and you’ll be surprised at how much more you can get done!


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 products, 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 an Automatic Cap Sealing machine into your line.


Why Use Capping Machines?

Automatic Capping Machines not only speed up the process of finishing the 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 several different capping machines that can help you pack more product in less time—and not just the machines that place the caps on, either.

How Can Capping Machines Benefit Your Business?

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, some machines 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.

Types of Capping Machines

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:

Chuck cappers: Chuck cappers work by placing a cap onto a container, and then sending it through the machine, where the moving parts spin the cap so it is sealed tightly. With this machine, the container is in continuous motion, rather than stopping at a spin station, as happens with spindle cappers

Spindle cappers: A similar machine to chuck cappers, instead these stop the containers at stations and spin the caps onto the container while the containers remain stationary.

Snap cappers: Snap cappers work by pressing a snap-on cap to each container as it traverses through the machine.

Vertical wheel pluggers: Finally, wheel pluggers are used where the containers being sealed require a plug instead of a cap placed on top.

What Industries Use Capping Machines?

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


  • Beverage and food
  • Distilled spirits and wine
  • Candles, lip balms, and molten products
  • Cleaning products
  • Pharmaceutical and medical
  • Paints, stains, and sealants (home improvement)
  • Personal care/health and beauty


When you are looking to buy a machine that can be used for capping bottles, you should definitely consider getting a ROPP capping machine or a roll on pilfer proof closure machine. These packing machines have been introduced many years ago but over the years they have improved in their technology and efficiency which ensures better performance each and every time. Basically these machines include a robust unthreaded aluminum shell which is placed over the neck of the bottle. As the machine presses down, it has numerous thread-forming wheels spin right around the shell to press against it. This helps to conform to existing threads of a bottle and the locking ring.


A ROPP capper is very similar to a chuck capper even though these machines do not involve any clutch mechanism. The ROPP capping machines can be purchased as single head systems or multiple head systems that come with high speed rotary features. A major advantage of ROPP capper machine is that it seals a product and delivers tamper evident security at the same time. However, a downside of using a ROPP capper is that it’s generally expensive to manage more than a single cap size. The threads and neck of the bottle has to be hard enough for withstanding the pressure needed to form the threads. For this reason, these machines are mostly used with hard plastic or glass.


The latest ROPP capping machines are designed and manufactured by using superior quality stainless steel materials and they also come with hard chrome plating and SS cladding to confirm complete resistance to corrosion and improved longevity. They also come equipped with single motor synchronized conveyor, platform turret and star wheel. The good thing about these machines is that they also feature self-lubricating properties which helps in reducing friction in a big way. The noiseless and smooth conveying of the capping process also makes them a hot favorite among various companies. Since they always deliver vibration free operation for all kinds of projects, they are always deemed useful for different types of projects. Additional features that come with these machines include an adjustable torque as well as low power consumptions with a low noise level. Many of the ROPP capping machines that are available these days include an acrylic cabinet, motorized height adjustment feature; a safety guard for protection and operation as well as specially designed hopper for increasing the storage capacity of the bowl.


The good thing is that there are multiple models of automatic and semi automatic machines these days that can be used for advanced bottle capping requirements. The productivity level associated with these machines varies greatly on the model that you opt for needs. This means that when you choose to buy these products for your business, you can expect your company to effectively deal with the market competition. Therefore, once you have decided to buy these machines, make sure that you consult a reputable manufacturer that can provide you with state of the art ROPP capping machines.


There are different cap types and sizes which seem unlimited, but the number of available capping machines is surprisingly low to cover all types of caps. Of course, unique container tops may require customized capping machinery. For almost all other caps, a small group of capping machines will “seal” the deal.

Types of Capping Machine

Spindle Capper Machine

Spindle Capping machines are probably the most popular capping machine produced for the packaging industry. These cappers use sets of matched discs to spin caps down onto bottles or other containers as they pass through the capping area on a conveyor system. Normally, three or four sets of discs will be used to gradually tighten caps. Elevators or vibratory bowls assist these continuous capping machines by delivering caps to each bottle, leaving the operator of the machine to simply replace bulk caps as needed. These capping machines can handle a wide range of screw-type caps, including flat caps, sports caps, trigger sprayers, and many more. The flexibility and ease of operation are two factors that make this capping machine popular.

Chuck Capper Machine

Chuck capping machines are similar to spindle cappers in that they work with screw caps. Chuck cappers normally consist of a metal chuck and a rubber insert matched to the capsize. Once a bottle is in place under the capping head, the chuck descends to apply consistent torque to each bottle and cap combination. Automatic chuck cappers may include multiple chucks to increase the capping machine speed. Handheld, semi-automatic, and tabletop chuck cappers will usually cap one bottle at a time. While one chuck and insert can handle different capsizes, a facility running both small and large-cap may require multiple chucks and/or chuck inserts. Chuck cappers are ideal for flat caps, but some modifications to the chuck and inserts allow for other screw-type caps to be run as well.

Snap Cappers & Lid Pressers

Snap cappers and lid pressers are both used for non-screw-type tops. Rather than being torqued onto the bottle, snap-type tops are simply applied using pressure and normally held in place by a lip on the container. The pressure is applied via a declined belt or a simple plunger depending on the application. Paint cans may work well in a lid presser, while plastic containers for some food and beverage products would use a press-on belt to avoid damaging the containers themselves. Snap cappers can be constructed very similarly to spindle cappers, with the spindle sets replaced by the decline belt, allowing snap caps to be sealed continuously as well, caps permitting. Spindle cappers and snap cappers can also be combined on one capping machine to handle an even wider range of cap types and sizes.

ROPP Capping Machine

A ROPP Capper (Roll On Pilfer Proof Capper) is somewhat of a speciality capper. ROPP cappers use specially designed knives to thread and seal tops onto containers. The most common product for a ROPP capping machine would be topping off a bottle of wine. Different bottle types and sizes may require different sets of knives when using this machine and this packaging machinery will not handle the variety of seals run by the spindle and chuck cappers. However, some ROPP capping machines can be manufactured to include a chuck-type capping head to expand the realm of caps that can be run.

Each of the capping machines discussed briefly above is available in different levels of automation, allowing this group of packaging machines to handle not just a wide variety of caps and bottles, but a range of production levels as well.
