An extrusion die is a tool used to produce a desired shape by applying pressure to a metal workpiece, causing it to undergo plastic deformation. Its basic structure comprises core components such as the die base, the female die (cavity), and the pressure ring; based on the process involved, these dies are classified into forward, backward, and lateral extrusion dies.
Extrusion dies are tools that use applied force to press a metal blank into a die cavity, causing the material to undergo plastic deformation and form the finished product. They are categorized into three types based on the forming method:
Forward extrusion die: The direction of material flow aligns with the direction of the punch's movement.
Backward extrusion die: The direction of material flow is opposite to the direction of the punch's movement.
Lateral extrusion die: Features a forming channel perpendicular to the direction of the primary applied pressure.
