- - - - A metal sheet is subjected to force to make a curved shape with a specific curve radius.
      - Uses
        
        Curved pieces
        
        Pieces with angles
    - - The heated metal is pushed through a hole by a piston, using compression
      - Uses
        
        Bars
        
        Tubes
    - - The metal is shaped using harmmers, tongs and anvils. Manual forging has been replaced by industrial or mechanical forging. The piece is usually hot.
      - Uses
        
        Railings
        
        Keys
        
        Rivets
    - - Uses

      - The heat metal is placed between two dies (fixed-mobile). The dies have the shape. They are pressed together and the piece take the shape.
    - - Metal is passed through rollers. They reduce its thickness and increase its lenght. The metal is usually hot.
      - Uses
        
        Sheets
        
        Plates
        
        Bars
    - - It is a cold forging process. The metal is hit with a punch to make the shape in a mould
      - Uses
        
        Hollow pieces
    - - A wire is pulled through a hole. A rotating drum is used to pull it through the hole. It increases its length and reduces its diameter.
      - Uses
        
        Metal strings
        
        Wires
