While different cap sizes and types are seemingly unlimited, it will take a surprisingly low quantity of capping machines to cover a lot of caps. Of course, unique and rare container tops might require custom capping machinery. For most other caps, a small number of capping machines will “seal” the sale.

SPINDLE CAPPERS. Spindle capping machines are one of the hottest capping machine produced to the packaging industry. These cappers use groups of matched discs to spin caps down onto bottles and other containers while they move through the capping area with a conveyor system. Normally, three to four sets of discs will be employed to gradually tighten caps. Elevators or vibratory bowls assist these continuous capping machines by delivering caps to every individual bottle, leaving the operator in the machine to only replace bulk caps as required. These capping machines are designed for an array of screw type caps, including flat caps, sports caps, trigger sprayers and more. A number of containers, including F-style containers (think about anti-freeze, an extended narrow container with a handle), can be run using the spindle capper and multiple containers require minimal changeover. The flexibility and easy operation are two factors that produce this capping machine popular.

CHUCK CAPPERS. Chuck capping machines act like spindle cappers in this they use screw caps. Chuck cappers normally include steel chuck as well as a rubber insert matched on the cap size. When a bottle is in place under the capping head, the chuck descends to utilize consistent torque to each bottle and cap combination. Automatic chuck cappers might include multiple chucks to increase the capping machine speed. Handheld, semi-automatic and tabletop chuck cappers will often cap one bottle during a period. While one chuck and chuck insert can handle different cap sizes, a facility running both large and small caps may require multiple chucks and/or chuck inserts. Chuck cappers are best for flat caps, however some modification on the chuck and inserts enable other screw type caps being run too.

SNAP CAPPERS AND LID PRESSERS. Snap cappers and lid pressers tend to be utilized for non-screw type tops. As an alternative to being torqued on top of the bottle, snap type tops are merely applied using pressure and normally located in place by way of a lip on the container. Pressure is used with a declined belt or even a simple plunger with regards to the application. Paint cans may match well in the lid presser, while plastic containers for some food and beverage products would use a press on belt to stop damaging the containers themselves. Snap cappers might be constructed very like spindle cappers, with all the spindle sets replaced by the decline belt, allowing snap caps to be sealed continuously also, caps permitting. Spindle cappers and snap cappers can also be combined on one capping machine to manage a much wider range of cap types and sizes.

Each of the capping machines discussed briefly above can be purchased in different degrees of automation, allowing this group of packaging machines to manage not only a wide range of caps and bottles, however a array of production levels too.
