Aluminum Machines

Aluminum capper is a general category that includes all types of metal closure cappers. The uses of metal caps, or metal closures, have been reduced due to the advent of more sophisticated plastic closures, which can handle the increased pressure associated with carbonation in soft drinks. These new types of plastic closures are usually injection molded. (See Plastic / Injection Molding.) Aluminum cappers are designed to apply aluminum roll-on closures or to apply crown metal closures to a container. The metal caps are applied in a similar method as a plastic closure. Chucks designed into the aluminum capper grip the magnetic closure and screw the cap onto the top of the bottle. Metal closures are often used to close wine or distilled spirits bottle.
