Die Casting Factory Parts Ring Machining Open Die Forging Press Steel
Open die forging is the process, which involves the shaping of any hot metal parts. This is done with a top die that is attached to a ram and the bottom die gets attached to a hammer or bolster. Metal parts need to have appropriate temperatures, somewhere in the range of 500°F to 2400°F. These can then be shaped into the desired configuration with the help of skilful hammering or even by applying pressure to the workpiece. Sometimes, open die forging is also referred to as free forging or impression die forging. The metal is constantly hammered and stamped to finally achieve a certain set of dimensions within the open die forging process.

Process procedure:
Forging process flow quality control: Raw material steel ingot into warehouse(test the chemical content) → Cutting→ Heating(Furnace temperture test) → Heat treatment after forging(Furnace temperture test) Discharge the furnace(blank inspection)→ Machining→ Inspection(UT,MT,Visal diamention, hardness)→ QT→ Inspection(UT, mechanical properties, hardness, grain size)→ Finish machining→ Inspection (dimension)→ Packing and Marking(steel stamp, mark)→ Storage Shipment
