A press for producing fine cut parts includes a tool holder, a cross-beam and a tool having a plurality of tool parts, wherein the tool includes a tool block. The tool holder includes a set of transmission devices. The cross-beam is drivingly connected, via the set of transmission devices, to at least some of the tool parts required to produce a fine cut part and arranged in the tool block. The cross-beam is actuated by at least two cross-beam drives.

A method of manufacturing a drainage base tray for a shower, the method including the steps of: a) providing a foldable sheet of metallic material; b) cutting a one-piece blank from the foldable sheet of metallic material; c) folding the blank along at least one folding line in order to define at least one corresponding slope within the blank, the slope having an upper portion and a bottom portion defining a sloping gradient; and d) providing the blank with a draining hole adjacent to the at least one folding line and in proximity of the bottom portion of the slope, for allowing waste liquid to drain via the draining hole of the drainage base tray. Also described is a resulting shower drainage base tray, and a one-piece blank made of metallic foldable material and having portions for manufacturing the shower drainage base tray. The present system also concerns a shower drainage kit including a grill component positioned, shaped and sized for placement over the shower drainage tray.

A method is for manufacturing a laminated steel sheet comprising laminated a predetermined number of thin steel sheets formed by punching a belt-shaped thin steel sheet into a predetermined shape. This method includes the following steps 1 to 3: step 1: a step of sequentially punching the thin steel sheet into a predetermined shape with a metallic die; step 2: a step of applying a curable composition to a predetermined portion of the thin steel sheet; and step 3: a step of irradiating the curable composition with energy rays. The curable composition is a delayed curable composition which is cured after a lapse of a predetermined time after being irradiated with energy rays.

There is provided an apparatus for manufacturing a thin uneven member. The apparatus includes a lower die fixed to a press bed, an upper die fixed to a ram and disposed opposed to the lower die, and a pressure-drive unit which presses the ram using a servo motor as a power source, the servo motor being fixed to a first support member. The pressure-drive unit includes a motion converting mechanism which converts a rotation of the servo motor to a linear motion of a lifting member, and a cylinder block connected and fixed to the first support member and including first and second pistons arranged in series vertically, wherein the first piston is connected to the lifting member through a second support member, and the second piston, larger in diameter than the first piston, presses the ram.
