Cold forging production process is done at room temperature. The work piece is squeezed between two dies until it takes their shape. To provide a finished, ready to fit component, the procedure includes rolling, pressing, drawing, extruding, heading and spinning.
Cold Forging Advantages
Sometimes producer may choose cold forging process as compared to hot forgings because cold forged parts need very less or no finish work, that means cost saving to customer. Another benefit with cold forging is saving in material achieved through exactness of the shape. The monetary advantages combined with high production rates and long die life are enough to convince many manufacturers to make components by cold forging process over hot forging wherever possible.
Cold Forging Disadvantages
Only simple high-volume parts can be produced cost effectively by cold forging method. Another major disadvantage is that cold forged metals are less ductile, which makes them unsuitable for certain configurations. Also, residual stress may occur because of the grain structure that gives the material its strength.
