What type of material can be used as a die in the blanking process?

In the blanking process, which is a forming method used to cut sheet metal into specific shapes, the material selected for the die must possess certain properties. Metal is the preferred choice because it offers the required strength, durability, and resistance to wear and deformation during the high pressures associated with blanking.

Metal dies can withstand repeated impacts and the forces exerted during the cutting process without losing their shape or structural integrity. This is crucial for maintaining precision in the cut parts and ensuring a longer lifespan of the die itself. Common metals used for dies include tool steels, which are specially formulated to enhance hardness and toughness, making them suitable for such demanding applications.

Wood, plastic, or composite materials generally lack the necessary mechanical properties and durability required for use in blanking dies. They may deform or wear down quickly under the high stresses of the blanking process, resulting in poor-quality parts and reduced efficiency. Hence, metal is the most suitable and effective material for this application.
