The Best Capping Machines That Can Be Used In The Packaging Industries

While types and sizes of caps are seemingly unlimited, it takes a shockingly low number of capping machines to cover the vast number of various caps. However, rare and unique container tops may call for custom capping machinery but for other caps, the following machines for capping will work surprisingly okay.

Spindle cappers

These capping machines are some of the commonly used in the packaging industry. They use sets of matched disc to be able to spin caps to the bottle or any other container on a conveyer system as they pass the capping area. In most cases, 3 to 4 sets of discs are used to tighten the caps. Vibratory bowls or elevators move these caps to individual bottles making the task funnier. These machines handle a range of screw types including:

1. Flat caps

2. Sports caps

3. Trigger sprayers

Chuck cappers

Just like spindle cappers, these machines work with screw caps. They consist of a metal chuck and a rubber that is inserted to match the cap size. Once the bottle is below a capping head the chuck comes down to apply torque to each cap and bottle combination. Automatic ones may include multiple chucks to increase the capping speed. These machines are ideal for flat caps but some modification of the inserts and chucks can give room for other screw caps.

Snap cappers and lid pressures

These machines are used for non-screw cap types. Instead of being torqued onto a bottle, snap type tops are applied with the use of pressure and help in place by a lid which is usually on the container. Pressure is applied with the use of a decline belt or even a simple plunger depending on the need. Paint cans works best on lid pressure while plastic containers for food and beverages would do well on a press on a belt so as not to damage the containers. It is possible to combine spindle and snap cappers on a single capping machine to handle a wider range of cap types.

ROPP Cappers

Roll on Pilfer Capper (ROPP capper) is a special capper. This is because they use specially designed knives to seal and thread tops onto the containers. The most common product that uses this capper is a wine bottle. Various bottle types may call for various sets of knives when these machines are being used, and they may not be able to handle variety of seals that are run by chuck and spindle cappers. However, some of the ROPP cappers can be manufactured to have chuck capping head and this way the number of the caps run with these machines is expanded.

Each of the above capping machines are available in various levels of automation, allowing these machines to handle not only a variety of bottles and caps but also a wide range of production levels!
