Abstract (en)
[origin: WO2006136708A1] The invention concerns a method for measuring the base (120) of impact-extruded cylindrical containers, based on the measurement of the temperature of the extruding equipment comprising a mobile part (10; 20) with a punch (10) actuated by a mechanical system (20) articulated from a reference point (23), said extruding equipment further comprising a passive part (30; 33, 34; 35) typically with a matrix (30) and support equipment (34; 35). The invention is characterized in that said temperature measurement is performed in a point of said passive part of the equipment, and in that, for a specific geometry of the container and a specific alloy, the thus measured temperature T is associated with the imposed production rate C and position X of said reference point (23) to estimate the thickness e obtained using a relationship R(e,T,X,C) = 0. Once established, said relationship enables the thickness base of the containers being manufactured to be controlled.
