The Forging Process

Different forging methods have different processes, among which the process of hot die forging is the longest. The general order is: blanking of forging blank; heating the forging blank; roll forging blank preparation; die forging forming; trimming; punching holes; correction; intermediate inspection, inspection of forging size and surface defects; heat treatment of forgings to eliminate forging stress and improve metal cutting performance; cleaning, mainly to remove surface scale; correction; inspection: general forgings shall be inspected for appearance and hardness, while important forgings shall be inspected for chemical composition analysis, mechanical properties, residual stress and nondestructive testing.
