Abstract: A Method for manufacturing metal sealing caps comprising a sequence of steps is provided herein.

Abstract: The invention relates to a manufacturing process of aluminum alloy beverage cans by «Drawing-Ironing», characterized in that a friction higher between the bodymaker punch and the aluminum sheet than between the ironing die and said aluminum sheet is produced by at least one of the following specificities: An aluminum sheet with an internal surface significantly higher in roughness than the external one Ironing dies with rounded intersections between infeed as well as exit surface and the land, with a smooth surface in the working area and a short width of the land A bodymaker punch with an extra roughness and an isotropic texture. It also relates to a beverage can manufactured by such a process, and characterized in that its reflectance measured at 60° is higher than 73% just after the last ironing step.

Abstract: A method for manufacturing a beverage can, a bottle or a spray can made of aluminium alloy, by means of deep drawing-ironing followed by necking and/or bending, from a non-circular blank.

Abstract: The invention relates to a method for ultrasonic inspection of an object wherein a multi-element ultrasonic probe comprising a plurality of basic transducers is applied to the object. The method comprises: consecutive activation of the basic transducers such that when activated each transducer emits an ultrasonic wave incident on said object, following each activation of a basic transducer, acquisition, by a plurality of basic transducers, of a detection signal representative of a wave reflected by the object during propagation of said ultrasonic wave in the latter. The object is divided into points referred to as mesh points. Each acquired detection signal is subsequently used to calculate, at each mesh point, a parameter representative of the object that is to reflect an incident ultrasonic wave. The method comprises, during this calculation, a selection of a group of transducers from among the basic transducers of the probe.
