- It is a cold process which consist of shaping sheet metal by pressing it between two moulds.
- Dies.
- A press. It could be a hydraulic or a mechanical press but first is more common.
- The hood and the doors of a car.
- It consist of a technique for manufacturing hollow or concave objects. It`s a cold forming process that consists of applying pressure to sheet metal with a mould called drawing punch and the pressure forces the sheet to stretch and adapt until it takes the shape of the mould.
- It is called drawing punch. To prevent the sheet metal from cracking or creasing.
- A hydraulic or a mechanical press.
- Hollow or concaves objects.
- Steel and aluminium.
- Plates, saucepans, cans, cups, and sinks.
- It’s a technique to draw several times in a row using different punches. It’s used when we have to create very deep objects with complicated shapes that cannot be made with one single draw.
- It consists in the cut of pieces from a thin sheet of material, normally metal, plastic, cardboard, or leather. This cut is made with a sudden movement: the material to be cut is pressed, with great force, between two tools, the punch and die.
- To change the shape of the punch and die. It’s not easy.
- Washers, boxes of cardboard, cards of cardboard
- It’s a machine that can cut any shape by simply changing the computer program that controls them. The difference is that they do not cut the material with one sudden movement. Rather, they make small repeated movements until the desired piece is cut.
- They are more flexible (they can cut a lot of shapes by simply changing the program).
- It consists in the bending of the sheet of metal to create objects.
- Bending machine or press. Between the punch and the die.
- Rain gutters, tool boxes, computer cases, and elevator doors.

5. It’s a bending machine with a robot that inserts and removes the sheets to be bent.
- It’s the process in which cast metal is pressed into a mold.
- Aluminium radiators , camera bodies, car wheels, and in general any type of piece that has a complicated shape can be made.
- They have a complicated shape.
- Metals with a low melting point , especially aluminium and its alloys.
- It’s a process in which molten metal is forced through an exit nozzle called a die. Due to the pressure the ram places on the molten metal, this metal must go through the die, which gives it its shape.
- Aluminum profiles used in doors and windows, seamless tubes, handrail.
- Aluminium and its alloys. Copper, lead and alloys of these metals because they have a low melting point.
- The die.
- That way the material can easily pass through the die when it is compressed.
- Billet. To a temperature that is similar to the temperature used to melt the metal.
