Shape matters At their headquarters in Eislingen/Fils, HINTERKOPF, the long-established packaging specialist develops and builds machines that are in worldwide use for the fully-automated production of cans, tubes and sleeves made from aluminum and plastics. Besides printing, coating and washing machines the HINTERKOPF product range also comprises capping and trimming machines and last but not least necking machines for aluminum cans and sleeves. In the necking process a can is given its final shape. In numerous steps the shoulder is formed, the edge is flanged, a thread can be cut if so required,...

N50.3 – Ready for DWI The necking machine N50.3 from HINTERKOPF with its 50 working stations opens up entirely new possibilities for the shaping of bottles and cans made of aluminum. In addition to very complex product forms also thin-walled products, e.g. made by the DWI-process, can be shaped in only one necking machine. Moveable and adjustable (in height and angle) infeed and exit conveyors for good access The proven hardware and control concept of the N40-series necking machines has been adopted and extended, ensuring also for the N50.3 highest precision and quality, flexibility, and the...

50 Processing stations, for DWI and complex shapes The manufacturers of consumer goods are increasingly using thinwalled aluminum for cans and bottles in order to save the valuable raw aluminum and also to reduce cost. Adding up to the 30% savings in material, recycled aluminum can alternatively be used with the DWI process. Consumers today ask for premium design with a recognition value, i.e. with individual shaping of the product packaging. For HINTERKOPF´s customers , the makers of aluminum cans or bottles, both facts mean that significantly more necking steps are required to shape the thin-walled...

Variable stroke with optimum speed HINTERKOPF is using the proven variable stroke mechanism from the N40 machine as well in the N50.3: Using this mechanism, both aerosol cans with shaping along the whole body and „simple“ products can be manufactured in the most efficient way, i.e. each with their respective maximum speed (see the table below). With a variable working stroke of 87 to 184 mm, a production speed of up to 200 parts/min. and a large range of diameters from 35 to 74 mm the N50.3 is a highly efficient, flexible machine for the shaping of demanding cans and bottles made of aluminum,...

Technology and overall concept Besides rotation-symmetric necking, also asymmetric embossing processes of the cylinder wall of cans or bottles can be accomplished with special tools. The new compact rotary tools with direct drives, used for milling, edge flanging or shoulder rolling can be installed at almost any working position of the tool plate of the N50.3. Up to 8 of these rotary tools can be used. As the exhaust suctions are arranged within the inner area of the tool plate, easy access for maintenance or tool exchanges is ensured. Besides an extremely precise, fast and reliable mechanical...
