combining a \"punch\" that applies force directly to the material to apply plastic deformation and a \"die\" that receives the material to which the force is applied.<br>There are various punches and dies depending on the shape of the material and the shape of the final purpose, and by combining them, forging and forging processes are performed as shown below.<\/p>\n\n\n\n<p><strong>Upset processing<\/strong><br>This is a forging and press-forming method that makes the material short and thick by tapping the material fixed with a die in the axial direction with a punch.<br>Used to machine the head of forged and pressed parts such as rivets and bolts.<\/p>\n\n\n\n<p><strong>Forward extrusion<br><\/strong>By tapping the material with a punch on a small diameter die relative to the original material diameter, the diameter of the material is narrowed down and the amount of extra material squeezed and the length of the material is increased.<\/p>\n\n\n\n<p><strong>Backward extrusion<\/strong><br>When the material is placed in a die and a force is applied with a small punch against the die material diameter, the material escapes into the gap between the die and the punch, resulting in a cup-shaped shape.<br>Used for forged parts machining and press-forged parts machining, such as caulked parts of rivets.<\/p>\n\n\n\n<div class=\"wp-block-columns sec-w-1350 mt-60
