Our flashless forgings allow our customers to chuck on the OD of the part without having to worry about a parting/trim line.Since the part is produced entirely in the bottom die there is a precise top to bottom die match on the OD.Most forgers avoid this type of forging because they cannot maintain the process controls necessary.What Is The Difference Between Forging And Rolling 3.Since there is no flash in the flashless die forging and closed upsetting forging,the material utilization rate is high.It is possible to complete the finishing of complex forgings with one process or several processes.Because there is no flash,the force-bearing area of the forging is reduced,and the required load is also reduced.What Is The Difference Between Forging And Rolling 3.Since there is no flash in the flashless die forging and closed upsetting forging,the material utilization rate is high.It is possible to complete the finishing of complex forgings with one process or several processes.Because there is no flash,the force-bearing area of the forging is reduced,and the required load is also reduced.

What is Flashless forging? - AskingLot

Explanation In closed die forging process no flash is formed.In closed die forging process,metal is kept in between pair of dies and a gutter is provided in the lower die.Explanation Cogging which is also called as drawing out is basically an open die forging operation.
