The shape makes the difference 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 bottles. 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...

N40.2 – highest flexibility The advanced N40.2 necking machine sets new standards in terms of precision, flexibility, quality and ease of operation and maintenance. Moveable and adjustable (in height and angle) infeed and exit conveyors for good access In the N40-series machines N40.2 and N40.3 a variable stroke and a new concept enables highest production speed. With the necking machine N40.2, even complex shapes can be produced with high quality and with a production speed up to 220 cans/min. The bearing arrangement of the machine consisting of linear ball slides makes the machine more precise...

40 processing stations for individual shaping Higher demands in respect to value and differentiation of consumer products lead to increased requirements on the overall design and appearance of the product´s packaging. For HINTERKOPF‘s customers, manufacturers of aluminum cans and bottles, this results in higher requirements on the decoration and in particular the product shape. New market requirements not only demand the forming of can or bottle necks, but the respective body has to be necked as well, for example by the formation of a characteristic “waist”. To do so, the body of the completely...

Variable stroke with optimum speed In order to create a can with a waist on the lower body, a large working stroke of the necking machine is needed. However, since all sorts of aerosol cans and bottles need to be shaped on this one necking machine, it does not always require the maximum stroke. Can bottom forming on one working station with a bottom forming punch HINTERKOPF therefore developed a variable stroke for the N40 machines, allowing the use of one single machine for shaping cylinders over their complete wall length or just for making the usual type of aerosol cans, each with its optimum...

Technology and overall concept Besides rotation-symmetric necking processes, also asymmetric embossing processes of the cylinder wall of cans or bottles can be accomplished. An automatic quality check of the finished can by a camera system is of course an option, a tightness check of the product in one of the work stations is under consideration. Besides an extremely precise, fast and reliable mechanical machine base, an advanced necking machine like the N40.2 requires much more: synchronized product handling including infeed and exit conveyors, the necking tools, the clamping chucks and also...
