If you work in pharmaceuticals, then you would realize that making medicines isn’t the entirety of your task – it’s also important to ensure that the containers in which these medicines stay are properly capped, so you can preserve their quality as much as possible.
To do this, you would need a proper capping machine. And as it turns out, there are actually several options available. This article will cover the different options, as well as how best they tend to work overall.
Overview of Capping Machines
The job of a capping machine is simple, really – when you take your product and place it in the container, a capping machine helps to apply the right cover to it, ensuring that you won’t need to do the manual work of covering it on your own.
As you would imagine, capping machines work in different fields. But, they are especially prominent in the pharma space, where it is especially important to ensure the quality of products. These machines come in different forms, so you can easily adapt your production technique to fit what you’re working with.
Types Of Capping Machines Based on Capping Mechanisms
So we now have a proper idea of what we are working with. Next, let’s look into the major types of capping machines, as well as the different iterations and operations where they especially shine.
Screw Capping Machines
If you are in the market for a capping machine, then there is a significant chance that the screw capping machine is probably what you are most likely trying to get. These machines are built to focus more on containers that have threaded necks, as they ensure seamless entry and capping regardless of the competing factors.
With screw capping machines, you basically get the container and feed it to the conveyor belt. From there, the machine places the cap, moving one cap from the sorting mechanism to the top of the container.
Finally, a capping mechanism applies enough torque to screw the cap on the container, with capping heads being designed to match the configurations of the caps themselves. You can adjust the torque if you want, so you don’t overseal the container. Verify the authenticity of your seal, and you are good to go!
In terms of functionality, there is a lot that you can get from screw capping machines. However, they tend to focus more on the following fields:
- Beverage manufacturing, where they help to seal bottles containing the beverages.
- The pharma space, where they seal containers that hold medicines.
- Food industry applications, as they are used to package products like condiments, enhancers, syrups, you name it.
- The making of cosmetics, where they help to ensure that things like creams and lotions are properly secured.
- Holding cleaning agents, samples, solutions, and more that are a part of the chemical industry.
ROPP Capping Machines
Another hugely popular option for a capping machine is the ROPP capper. Short for “Roll-On Pilfer Proof,” the ROPP capping machine allows you to place caps made of aluminum on your containers. In most cases, you will find that these machines work with caps that have serrated edges and deep skirts, and it becomes incredibly easy to roll them on the necks of the bottles to offer a reliable seal that prevents any form of tampering.
For that optimal strength and reliability, these cappers are more than effective. And, they work for some of the following spaces:
- The beverage industry, where they mostly help in covering bottles with alcoholic content.
- The pharma space, where they help to seal bottles that hold syrups and other formulations in the liquid state.
- The personal care industry, where they help to seal things like colognes and other liquid components.
- Hospitals and healthcare locations, where they help to seal bottles that contain things like lab chemicals and diagnostic reagents.
Snap Capping Machines
The beauty of snap capping machines lies in the working principle of the types of caps they offer. Instead of traditional caps that need to be twisted or screwed on, these caps are essentially snapped on, making them a refreshing break from the norm.
With their speed and efficiency, snap covers are easily becoming the industry standard. And as you would imagine, the machines that help to implement them are also quickly becoming a major part of many operations.
In most cases, you will find snap cappers in the beverage space. This is because they help to offer easy access to products – carbonated drinks, juices, beverages, and more. However, we’ve also seen them work in spaces like pharmaceuticals, cosmetics, and even the development of cleaning products. Some makers of automotive fluids and lubricants also use them, taking advantage of the ease of use that snap covers offer.
Press-on Capping Machines
The name here pretty much says it all – when you need to apply press-on caps to containers, these are the machines to be used. In most cases, you will find press-on capping machines with flat tops and skirts that are pressed on the opening of the container. This combination helps to create a proper seal, with the machine eventually covering the container and protecting the products that you have in it.
Basically, press-on capping machines are used in any industry where you have the other types of capping machines. This means that everything – from food production to pharmaceutical and healthcare products to cosmetics – can make use of the machines. Interestingly, these machines also work in the cleaning products industry, where they help to protect cleaning agents, detergents, and other products that are mostly used at home. As long as the products need to be properly sealed, then the press-on capping machines easily work with them.
Types Of Capping Machines Based On Automation Level
While it’s easy to classify capping machines based on the way they work, it’s also critical to understand a new classification structure – level of automation. In a world where just about every industry has now been disrupted by automation, manufacturers need to be aware of the different options they have available to them when it comes to capping machines.
So, here’s what we have:
Manual Capping Machines
First on the list is the manual capping machine. Essentially, these are simple devices that are held by hand and they allow you to apply lids or covers to containers. As the name suggests, the machines are operated by hand, and they work best for small-scale production where you might not need so much automation or you might not be working with so many containers at the same time.
The benefits of manual capping machines are easy to see. You can operate them with little setup, and maintenance isn’t so much of a chore. Plus, you can easily adapt them to fit different sizes of caps, so you don’t need to worry much in terms of the perfect fit or versatility.
That said, as you can imagine, the limitations of these machines lie in the fact that they don’t necessarily work for high-volume needs. They rely more on manual labor, and there’s a high chance that you won’t be able to get a reliable amount of speed and efficiency from them.
Semi-Automatic Capping Machines
If you are a drug maker, there’s a significant chance that you would want to scale up your operations at some point. And if you’ve been making use of just manual capping machines, this might mean upgrading to a semi-automatic option.
As its name suggests, this is a capping machine that brings in elements of the automatic option as well as the manual option. With the semi-automatic capping machine, you get a more streamlined capping process, although this doesn’t mean that you still won’t have to deal with some form of manual operation nonetheless.
To operate these machines, simply prepare your containers and place the caps on them by hand. Activate the capping mechanism, and let it run as it should. Once the capping is done, you can make adjustments if you need to and just go ahead to verify what has been done.
The benefit of these capping machines lies in their ability to offer the perfect balance between manual and fully automatic operations. And this way, they can help you to become more efficient and consistent with your general capping. Plus, they do so while still being relatively affordable, so budget-conscious manufacturers can always lean on this benefit as they operate.
Fully Automatic Capping Machines
On the final end of the spectrum, we have the fully automated capping machines. These industrial grade machines help to place caps on containers accurately and efficiently, thus optimizing high-volume production to a considerable degree.
As you would imagine, the benefit of these machines is that they provide automation across the board. So, you really barely have to do anything to get them to work. Here, the containers are automatically fed into the capping machine, with the machine itself supplying the caps through a feeder system. With belts or wheels, the caps are placed on the containers, then the capping process goes ahead to take place.
Thanks to their fully automated setting, these machines even come with features that allow them to adjust their operations based on the type of container they are working with. They are completely adjustable, and you can easily integrate them into whatever setting you are working with to ensure that you never have to worry about moving along in the automated production process.
Overall, fully automatic capping machines offer a reliable and efficient solution for high-volume capping requirements in various industries. In all honesty, it really doesn’t matter what industry you work with – these machines help in contributing to increased productivity and consistency in product packaging, allowing you to relieve yourself of any stress.
How To Choose A Capping Machine
From what we’ve said, you can easily see that there are so many capping machines to work with. And if you are building your production line, you need to know how best to choose a machine to work with. So, here are a few things you would want to keep in mind:
How Much Do You Want To Produce?
First, you need to have an idea of your ideal production volume. If you are engaging in high-volume production and you care about efficiency, then it might not be so ideal to have anything that is not automated.
What Types Of Containers Are You Using?
It’s also important to keep an eye on your container and cap types. You might need to use different capping machines for different container and cap sizes, so focus on compatibility and ensuring a seamless fit across the board.
Is There Enough Torque?
As an extension of the point above, you also want to make sure that your machine has enough torque to accommodate the size range of your container and cap. If this isn’t the case, then the quality of the cap itself will be significantly affected.
Make Sure You Have Enough Space
Before you make a choice, we recommend that you look into the amount of space you have in our production facility and consider your production line’s layout. Your capping machine should be able to fit within your space constraints, and you need to be able to integrate it seamlessly into your current setup
How Easy Is It To Use?
To help ensure that you don’t run into issues in production, we recommend that you also focus on optimal maintenance and ease of use. Intuitive controls, tool-less changeover, and easily accessible maintenance should be the main focus here.
How Much Can You Afford?
Finally, always ensure that your capping machine is affordable enough. The budget constraint topic is one that many manufacturers have to accommodate at the end of the day, and you need to ensure that you have enough money to afford the machine you are looking to get.
