HIL-46/48 NG: Compact System for internal coating of aluminum Tubes

The HIL-46 NG internal coating machine for collapsible tubes impresses with its cost-, space- and energy-optimized coating concept. The internal coating machine, which is based on standard assemblies, is enhanced by energy-­optimized system components, such as annealing furnaces and internal coating driers. Optionally, the machine can also be designed with an electrically heated evaporation zone as „HIL-48 NG“ to achieve the best coating results through intermediate drying between the individual coating processes.
