What Is Capping Machinery?
Capping machinery is used to put caps and stoppers on bottles. Capping machinery can automatically and quickly press into the bottle, a task that is difficult to do manually. For soft materials such as PET bottles, the body of the bottle may be crushed by the stoppering process, and a neck holder is used to reinforce the bottle. There are different types of neck holders depending on the size and strength of the bottle.
There are a variety of products, from large capping machinery used in factories to simple manual capping machinery that can be used in small stores.
Uses of Capping Machinery
Capping machinery is used for filling and capping bottles with liquids. Since they can be used to stopper glass bottles, PET bottles, etc., they are used to stopper soy sauce, dressing caps, etc. They can also be used to stop ice cream cups. Other applications include ice cream cup lids. In the case of ice cream cups, the lid is often lightly tightened by the user to prevent the container from being crushed and then the manual capping machinery is used to ensure that the lid is securely fastened.
There are two types of screw caps: those with fins and those without fins, but most capping machinery can handle either type.
Principle of Capping Machinery
The principle of capping machinery is that the machine physically presses the cap or cork into the bottle from above. In some cases, the cap is tightened by turning it like a screw cap.
In most manual capping machinery, the user puts the lid on the bottle themself. When a switch or lever is pressed, the capping machinery comes down from above and corks the bottle. Those using a foot switch are safer because there is no risk of pinching the hand.
In automatic capping machinery, the machine does everything from putting the lid on. Some products combine a filling machine and capping machinery into a single unit. Depending on the type of lid or bottle, the height of the head and the speed at which the product flows are adjusted.
Various shapes of stoppers can be produced by changing the head. The variety of closures that can be corked includes cosmetics and food containers, beer crowns, wine corks, PET bottles, soy sauce, and dressing bottles, spouted pouches, and more. Capping machinery with an air cylinder can be used for corks with a pointed tip without crushing the tip.
