Cap closing machines are essential equipment used in bottling automation industries. A capping
machine’s main function is to employ a plastic or metal lid, snap, or caps accurately and
securely to a jar, container, or bottle. These pieces of equipment ensure hygienic workspaces,
high production output, high speeds, and in-budget manufacturing costs.
How To Select The Best Cap Closing Machine
1. Know your cap closure:
Both suppliers and end-users are concerned about the cap closures. This is one of the most
crucial tips you must understand. You must completely understand all the configurations,
tolerances, and dimensions of your cap closures before you order a capping machine.
For example: What sort of pressure does a screw-up closure take? You might be able to use 20
to 30 times more force, but how many times do you have to rotate the cap? Often, packaging
companies don’t take into consideration what type of closure, balance torque, and removal
torque is required by the customer or a business. Induction sealers add another vacillating
factor, as they may loosen caps, requiring more torque.
Additionally, every cap closure has a breakdown time which you need to know because it may
loosen on the shelf. Be aware of this information and discuss it with your supplier.
2. Consider your consumer along with the machine:
The cap has to confluence with both. Examine the size of the bottle opening from both a filling
and expulsion standpoint. Also, figure out whether to use single-closure or two- or three-piece
cap closures. The configurations of the package must be considered first, and then you should
explore the type of feeding and filling system you need to deliver.
3. Consider future closure needs:
Like any other packaging machine, try to be prepared for future needs. Cap closing machines
should be able to deal with a variety of different types of caps over time. Over the years, cap
designs have changed a lot and have become increasingly complex: For example, spray-
through caps must be aligned with the bottle.
4 . Rotary capper considerations:
When dealing with rotary machines, consider the number of heads and the feeding method. The
most crucial factor here is to look at how the cap is applied to the container. Be careful with the
capper’s centering mechanism and anti-rotation parts to ensure perfect cap closure placement.
5. The speed:
The capping machine should be able to accommodate heads that are required to achieve your
current line speed. Also, make sure the machine can add heads later for higher-speed
applications.
6. The closure design compatibility with the machine:
It’s critical to know how the cap design will go with the machine function. You must know the
height and diameter of the part, the length of the part, as well as the weight to determine if it will
be compatible or not. Once you know the proper design and dimensions, you can assist those
through the design of your machinery, which will help achieve more reliable and smooth
operation when capping and handling.
7. Test tolerances:
Be careful of what container and closure packagers are offering in terms of tolerances. Test the
opposite extremes' tolerances and see how the machine handles them. This will give a valuable
insight into how flexible the machine will be with borderline materials.
8. Examine handling and stabilizing:
For some lighter-weight plastic containers and bottles, you’ll need to observe the functioning
machine to evaluate how well it holds the container tightly in place during the capping
application and sealing application to assure a tight seal, especially for food and beverages.
9. Test bad inputs:
Employ induced failure testing, meaning deliberately feeding in the wrong container and the
wrong closure. This gives you an insight into what happens on the shift when operators may be
tired or are not aware of their surroundings. This may also give you a view of what happens
when the material is loaded in the wrong way or if operators deploy the wrong caps? Will the
bad inputs break the capping machinery? These are some questions, that you need to know
before employing any capping machinery in your warehouse.
