Control systems for tightness Control systems for the tightness of cups and buckets check if the closed containers are correctly sealed and thus care for “full enjoyment” of the consumer. Only a satisfied customer is a regular customer. We offer a variety of different control systems for the tightness in order to guarantee “full enjoyment” of the consumer. Available functional principles: - thermic control system for the tightness - control system for the tightness with squeezer - control system for the tightness with vacuum Our control systems for the tightness are assembled as upgrades on existing machines. It is, however, possible to assemble the system as “stand-alone-machine” to the transportation process of the filling machine. The identified leaky containers are discharged after the filling process.
