Abstract: A process for shaping a high strength container, particularly an aerosol container and a container obtained through such process. Generally, aerosol containers made of aluminum or tin are obtained by conventional embedding processes from sheet disks and have cylindrical bodies with upper tapering finishing at a curl for fixing a valve cover and are closed by convex and profiled cross section bottoms, for forming a support region for upstanding the container. The bottom of such containers is obtained before tapering by means of a blow or front shock once the cylindrical body having planar circular base is shaped, this impact causing undesirable stresses on the body side wall and material accumulation at the annular region joining with this wall since the bottom thickness is not uniform. The invention proposes a process for shaping this kind of containers by extrusion thus saving material as a consequence of imparting the container with thin walls due to a substantial change in the production concept, giving concave shape to the base for avoiding undesirable stresses on side wall during further production steps and saving material at the joints with the side wall. The invention also relates to a particular shape container, having no material accumulation at the concave bottom, which may be used in different positions, horizontal or vertical aided by plastic or metal accessories.

Abstract: In a die cushion apparatus, a pressurizing force acting on a die cushion pad is applied to a first piston of a hydraulic cylinder unit by the operation of a slide, the first piston slides inside a first cylinder and pressure oil in a first hydraulic chamber is pressurized. The first hydraulic chamber is linked to a second hydraulic chamber of a booster cylinder unit via a second check valve, so that the pressure oil of the first hydraulic chamber is pushed out into the second hydraulic chamber. When the pressure of the first hydraulic chamber is applied to a second piston, the second piston slides inside the second cylinder and gas of a gas pressure chamber is compressed, whereby a surge pressure is reduced.

Abstract: A drive for use in the manufacture of cans comprises a hydraulically powered guide pod to which a hold down assembly is attached. The guide pod slides along a guide rod which is fixed in the bodymaker. Forward and rear hydraulic chambers are defined between the pod and the guide rod by means of bushings and a seal. Passage of fluid through ports to and from the chambers causes the pod and hold down assembly to move forwards and backwards. The length of the stroke can be set by the distance between the ports. A rotary valve is used to control the timing of the drive and control flow of hydraulic fluid, which is typically obtained from the bodymaker coolant supply.
