Capping Machines for the Packaging Industry

While different cap sizes and types are seemingly unlimited, it takes a surprisingly low quantity of capping machines to pay for most of caps. Of course, unique and rare container tops may necessitate custom capping machinery. For most other caps, a smaller group of capping machines will “seal” the sale.

SPINDLE CAPPERS. Spindle capping machines are probably the most widely used capping machine produced to the packaging industry. These cappers use multiple matched discs to spin caps down onto bottles or other containers as they go through the capping area on a conveyor system. Normally, three or four multiple discs will likely be used to gradually tighten caps. Elevators or vibratory bowls assist these continuous capping machines by delivering caps to every one individual bottle, leaving the operator with the machine to simply replace bulk caps if required. These capping machines can handle many screw type caps, including flat caps, sports caps, trigger sprayers and others. A variety of containers, including F-style containers (think of anti-freeze, a long narrow container with a handle), can be operate on the spindle capper and multiple containers require minimal changeover. The versatility and ease of operation are two factors that will make this capping machine popular.

CHUCK CAPPERS. Chuck capping machines are similar to spindle cappers for the reason that they use screw caps. Chuck cappers normally consist of a metallic chuck as well as a rubber insert matched towards the cap size. When a bottle is place beneath the capping head, the chuck descends to utilize consistent torque to each and every bottle and cap combination. Automatic chuck cappers can include multiple chucks to boost the capping machine speed. Handheld, semi-automatic and tabletop chuck cappers will most likely cap one bottle at any given time. While one chuck and chuck insert are designed for different cap sizes, a center running both small and large caps might require multiple chucks and/or chuck inserts. Chuck cappers are ideal for flat caps, but some modification on the chuck and inserts permit other screw type caps being run too.

SNAP CAPPERS AND LID PRESSERS. Snap cappers and lid pressers tend to be employed for non-screw type tops. Instead of being torqued to the bottle, snap type tops are simply just applied using pressure and normally held in place by the lip about the container. The stress is applied by way of a declined belt or even a simple plunger with regards to the application. Paint cans may fit well inside a lid presser, while plastic containers for some food and beverage products would make use of a press on belt to stop damaging the containers themselves. Snap cappers can be constructed nearly the same as spindle cappers, together with the spindle sets substituted with the decline belt, allowing snap caps to get sealed continuously also, caps permitting. Spindle cappers and snap cappers may also be combined one capping machine to manage a much wider array of cap types and sizes.

Every one of the capping machines discussed briefly above can be bought in different degrees of automation, allowing this group of packaging machines to take care of not just a wide range of caps and bottles, but a range of production levels at the same time.
