Capping machinery can take many different forms, often depending on the type of capping used and the level of automation required. When production demands reach a certain level, automatic capping machines become almost a necessity, but even for low to medium production facilities, these packers have benefits. 1. Speed Automatic capping machines can also increase the number of bottles or containers that are sealed on a production day. Manual capping, even with semi-automatic caps, takes time because each requires the operator to manually place the cap on the container before tightening it. Automatic machines include a cap delivery system that allows the operator to dump bulk caps into the hopper from time to time. 2. Versatility Most automatic capping machines can handle a wide range of cap types and sizes as long as the tightening principle is the same.
