It is a die type which reduces the heat transfer from hot sheet to dies, cutting/piercing tools, and blank holder in necessary zones in the way process conditions require and can increase it in die hardening by heat treatment effect, contrary to the approach used for stamping of hot workpieces between cold dies. This die type has the capability of forming the sheet and making forming process by heat transfer in necessary zones simultaneously according to the properties of workpiece. |
