This Tube Filling Line is designed with a precision recirculating nest transported by a cam-driven walking beam mechanism and a lower return conveyor. Nests are easily replaceable for easy conversion to other sizes. Various loading and unloading mechanisms are available to suit the application. One operator can easily run multiple lines at the same time. Bulk melting, storage, and transport are also compliments to this line. Temperatures can be monitored, recorded, and/or sent to your network system.
