The process where the metal is allowed to flow in some pre-determined shape according to the design of die, by a compressive force or impact, is known as: Correct Answer Cold forging

Explanation:

Cold forging is a metal shaping & manufacturing process in which bar stock is inserted into a die and squeezed into a second closed die.

  • The process, completed, is at room temperature or below the metal’s recrystallization temperature to form a metal into a desired shape or configuration.
  • Cold forging is an efficient and economical metal deforming process for the production of high volumes of parts at low cost.
  • There are three methods of cold forging that differ according to temperature, which can be cold, warm, or hot and involve the use of hammers, dies, or presses to shape, squeeze, deform, and roll metals.
  • Cold forging should not be confused with machining or casting since the end result is a stronger and higher quality product.
  • Unlike warm or hot forging, cold forging shapes and deforms bar stock at room temperature using localized, compressive force.
  • Depending on the requirements of the parts design, the workpiece may pass through multiple dies or be struck several times in succession to achieve the proper shape.


Thus, option (4) is the correct answer.
