Capping machines screw or press caps onto containers. Four-wheel and single-head types are available. The machine is selected to the cap and container.
Closing a container usually takes three steps: getting caps to the machine, putting the cap on, and, where needed, sealing the mouth under the cap. Which options a bottle line uses depends on the cap, the container, and the line speed.
Caps are loaded into a hopper and lifted on a belt. Caps lying the wrong way drop back, and correctly oriented caps slide down a chute to the capper, so nobody has to load caps by hand at the capping machine. Each elevator is built for one cap size and customised to a cap sample. Compressed air is supplied by the customer.
A four-wheel automatic capping machine closes the cap with spinning wheels as the bottle passes. It handles plastic or metal round caps, pump caps, spray heads, and duck-bill caps, and its capping speed and tightness can be adjusted. A single-head automatic capping machine uses a servo-driven head and screws on one cap at a time to the set torque; it is intended for screw caps, with other caps on request. If your caps include pump heads or spray heads, start with the four-wheel type. For plain screw caps either may suit, and the choice is confirmed against your samples.
Where a leak-proof or tamper-evident seal is needed, an induction sealer is placed after the capper. The cap must carry an induction foil liner that suits the bottle material. The sealing head heats the foil without touching the bottle, and the foil bonds to the mouth. MARVISCO offers a water-cooled induction foil sealer that works in cycles, and a water-cooled inline induction sealing machine that seals bottles as they move on the conveyor, before labeling.
Speed, torque, and sealing settings are confirmed on the quotation.
